User Password vs. Certificate based authentication

We have used the iPhone since day one and grown from 20 to 400 users over the years. Now managability is an issue and certificate based authentication is about to be replaced with user password only. Critics deny cutting some slack because of possible man in the middle attack scenarios. Is it true that user password can be exposed between the device and exchange server? Is it possible to read User/Password using a man in the middle attack?

Another Question about Certificate-based Authentication

Hello,
I was successful in PDC-based authentication, but have the
requirement to further improve this.
For this, I have to use the "Match Certificate in LDAP"-feature.
I have modified a user to include a "userCertificate"-attribute,
and pointed the parameters to access to the directory server.
Until now, I had no success.
In the Logfile "amAuth"-Logfile I can see this message:
<------------------>8-------------------->8------------------------>
com.sun.identity.authentication.spi.AuthLoginException: Error in locating registered certificate
<------------------>8-------------------->8------------------------>
In the Directory Server log, I can only see a successful bind-request,
but, interestingly, no search:
<------------------>8-------------------->8------------------------>
[28/Sep/2004:10:47:17 +0200] conn=3352 op=-1 msgId=-1 - fd=109 slot=109 LDAP connection from 127.0.0.1 to 127.0.0.1

Hi there
I got a couple of doubts about the Certificate Authentication module, maybe you can help!
First, have you made any documentation on how you made this work ? Is it at all possible to get the source code of the module you have made? I think I'll need to create a costum module aswell because of very specific client requisits.
My problem ( and I'll be posting a new thread with this, but just in case you have this on your watch list ) is that I need to have both user/password and Cert Based authentication enabled. I'll create a chain with both modules as sufficient. My problem is : the documentation tells me that I need to have the containers (I suspect both the server and the agents ) with SSL enable and (and this is the tricky part) with Client Authentication Enabled . Now my problem is : when on the http listener, I configure it with security and enable that listener with Client Authentication, when I try to access the container on the secure listener I get an error (in firefox) or the browser asks me to select a certificate ( on IE ). When I dont provide a certifica it gives me the same error as firefox.
Basically, what I believe is happening is that with Client Authentication, the container will always request a certificate from the browser. Which isn't exactly what I want. I need to AM protected resources on this specific realm to allow authentication of a user based on a user/password OR a Certificate.
Basically what I want to know is : do I need to have Client Authentication Enabled on the http listener ? Did I miss read the documentation? Is there a really good how-to on how to do this ? Can you give me a hand?
Thanks loads for your help

Certificate based authentication for Exchange ActiveSync in Windows 8.* Mail app

I have a Surface Pro and want to setup access to my company's Exchange server that accepts only Exchange ActiveSync certificate-based authentication.
I've installed server certificates to trusted pool and my certificate as personal.
Then I can connect thru Internet Explorer, but this is not comfortable to use.
I don't have a password because of security politics of our company. When I'm setting up this account on my Android phone I'm using any digit for password and it works perfectly.
Can someone help to setup Windows 8 metro-style Mail application? Does it supports this type of auth? When I'm trying to add account with type Outlook, entering server name, domain name, username, 1 as a password then I've got a message like "Can't
connect. Check your settings."
Is there any plans to implement this feature?

For what it's worth we have CBA working with Windows 8.1 Pro. In our case we have a MobileIron Sentry server acting as an ActiveSync reverse-proxy, so it verifies the client cert then uses Kerberos Constrained Delegation back to the Exchange CAS, however
it should work exactly the same to the Exchange server directly. I just used the CA to issue a User Certificate, exported the cert, private key and root CA cert, copied to the WinPro8.1 device and into the Personal Store. Configured the Mail app
to point at the ActiveSync gateway, Mail asked if I would like to allow it access the certificate (it chose it automatically) and mail synced down immediately...
So it definitely works with Windows Pro 8.1.

Certificate based authentication with sender SOAP adapter. Please help!

Hi Experts,
I have a scenario where first a .Net application makes a webservice call to XI via SOAP Adapter. Then the input from the .Net application is sent to the R/3 system via RFC adapter.
.Net --->SOAP -
>XI -
>RFC -
R/3 System
Now as per client requirement I have to implement certificate based authentication in the sender side for the webservice call. In this case the .Net application is the "client" and XI is the "server". In other words the client has to be authenticated by XI server. In order to accomplish this I have setup the security level in the SOAP sender channel as "HTTPS with client authentication". Additionally I have assigned a .Net userid in the sender agreement under "Assigned users" tab.
I have also installed the SSL certificate in the client side. Then generated the public key and loaded it into the XI server's keystore.
When I test the webservice via SOAPUI tool I am always getting the "401 Unauthorized" error. However if I give the userid/password for XI login in the properties option in the SOAPUI tool then it works fine. But my understanding is that in certificate based authentication, the authentication should happen based on the certificate and hence there is no need for the user to enter userid/password. Is my understanding correct? How to exactly test certificate based authentication?
Am I missing any steps for certificate based authentication?
Please help
Thanks
Gopal

Hi!
Although soapUI is a very goot SOAP testing tool, you can't test certificate based authentication with it. There is no way (since I know) how to import certificat into soapUI.
So, try to find other tool, which can use certificates or tey it directly with the sender system.

Certificate based authentication

I have a client application that requires certificate based authentication.
I could not find any instructions on how to set this up in the 11g manuals. So I reverted to the 5.2 manual (http://docs.oracle.com/cd/E19850-01/816-6698-10/ssl.html#18500), and followed some instructions found online.
I have completed the setup, and the client is able to authenticate using his certificate, and I have verified this in the logs.
[22/Mar/2012:13:13:33 -0500] conn=34347 op=-1 msgId=-1 - SSL 128-bit RC4; client CN=userid,OU=company,L=city,ST=state,C=US; issuer CN=issuing,DC=corp,DC=company,DC=lan
[22/Mar/2012:13:13:33 -0500] conn=34347 op=-1 msgId=-1 - SSL client bound as uid=userid,ou=employees,o=company
[22/Mar/2012:13:13:33 -0500] conn=34347 op=0 msgId=1 - BIND dn="" method=sasl version=3 mech=EXTERNAL
When adding the usercertificate attribute to the ID I used the following LDIF:
version: 1
dn: uid=userid,ou=employees,o=company
changetype: modify
replace: userCertificate
usercertificate: < file:///home/user/Certs/usercert.bin
the file was a binary encoded certificate file.
Here is the part that I don't understand when I do a search (or LDIF export) of the user object with the certificate it just returns a short base64 encoded string. when I decode this string, it is just the literal string of "< file:///home/user/Certs/usercert.bin".
So it appears that the certificate has not been stored on the user object in binary, and yet the certificate authentication still works. The file mentioned, does not exist on the LDAP server (the cert was loaded from another server), so there is no way that it is reading the cert from the file.
Anyone have any idea what is going on here? And why certificate auth works, when there appears to be not cert stored in LDAP?
If by chance this is how it is all suppose to work, then how do I go about backing up the usercertificate attribute when I do my LDAP data backups?
Thanks
Brian

Cyril,
Thanks for the reply.
I believe I am doing both types of certificate authentication, you are describing. My issue is that when I perform the steps to store the PEM formatted cert into the directory server, rather than storing a binary value of the cert, it appears to be storing the path to the file I attempted to import. The odd part is that I can still authenticate even after this is done.
I tried to post as much info as I could before without posting any sensitive data, I'll try and expand on that below.
Here is my documentation of the steps taken to configure the server and setup a user, for what I believe to be certificate based authentication, where the user is authenticated solely on the certificate that they provide (no password is sent).
1. Server must be running SSL, all connections for Certificate Auth are done over SSL (just a note)
2. From the DSCC
----a. Directory Servers Tab -> Servers Tab -> Click Server Name
----b. Security Tab -> General Tab
----c. In "Client Authentication" section, select:
--------i. LDAP Settings: "Allow Certificate-Based Client Authentication"
--------ii. This should be the default setting.
3. On the directory server setup the /ldap/dsInst/alias/certmap.conf file:
----a. certmap default default
----default:DNComps
----default:FilterComps uid,cn
4. restart the directory server
5. Do the following to setup the user who will be connecting. On their unix account (or similar)
----a. Create a directory to hold the certDB
--------i. mkdir certdb
----b. Create a CertDB
--------i. /ldap/dsee7/bin/certutil -N -d certdb
------------1) Enter a password when prompted
----c. Import the CA cert
--------i. /ldap/dsee7/bin/certutil -A -n "OurRootCA" -t "C,," -a -I ~/OurRootCA.cer -d certdb
----d. Create a cert request
--------i. /ldap/dsee7/bin/certutil -R -s "cn=userid,ou=company,l=city,st=state,c=US" -a -g 2048 -d certdb
----e. Send the cert request to the PKI Team to generate a user cert
----f. Take the text of the generated cert & save it to a file
----g. Import the new cert into your certdb
--------i. /ldap/dsee7/bin/certutil -A -n "certname" -t "u,," -a -i certfile.cer -d certdb
----h. Create a binary version of cert
--------i. /ldap/dsee7/bin/certutil -L -n "certname" -d certdb -r > userid.bin
----i. Add the binary cert to the user's LDAP entry (version: 1 must be included - I read this in a doc somewhere, but it doesn't seem to matter)
--------i. ldapmodify
------------1) ldapmodify -h host -D "cn=directory manager" -w password -ac
------------2)
------------version: 1
------------dn: uid=userid,ou=employees,o=company
------------sn: Service Account
------------givenName: userid
------------uid: userid
------------description: Service Account for LDAP
------------objectClass: top
------------objectClass: person
------------objectClass: organizationalPerson
------------objectClass: inetorgperson
------------cn: Service Account
------------userpassword: password
------------usercertificate: < file:///home/userid/Certs/userid.bin
------------nsLookThroughLimit: -1
------------nsSizeLimit: -1
------------nsTimeLimit: 180
After doing this setup I am able to perform a search using the certificate:
ldapsearch -h host -p 1636 -b "o=company" -N "certname" -Z -W CERTDBPASSWORD -P certdb/cert8.db "(uid=anotherID)"
This search is successful, and I can see it logged, as having been a certificate based authentication:
[23/Mar/2012:13:25:20 -0500] conn=44605 op=-1 msgId=-1 - fd=136 slot=136 LDAPS connection from x.x.x.x:53574 to x.x.x.x
[23/Mar/2012:13:25:20 -0500] conn=44605 op=-1 msgId=-1 - SSL 128-bit RC4; client CN=userid,OU=company,L=city,ST=state,C=US; issuer CN=issuer,DC=corp,DC=company,DC=lan
[23/Mar/2012:13:25:20 -0500] conn=44605 op=-1 msgId=-1 - SSL client bound as uid=userid,ou=employees,o=company
[23/Mar/2012:13:25:20 -0500] conn=44605 op=0 msgId=1 - BIND dn="" method=sasl version=3 mech=EXTERNAL
If I understand correctly that would be using the part 2 of your explanation as using the binary encoded PEM to authenticate the user. If I am not understanding that corretly please let me know.
Now the part that I am really not getting is that the usercertificate that is stored on the ID is as below:
dn: uid=userid,ou=employees,o=company
usercertificate;binary:: PCBmaWxlOi8vL2hvbWUvdXNlcmlkL0NlcnRzL3VzZXJpZC5iaW4
which decodes as: < file:///home/userid/Certs/userid.bin
So I'm still unclear as to what is going on here, or what I've done wrong. Have I set this up incorrectly such that Part 2 as you described it is not what I have setup above? Or am I missunderstanding part 2 entirely?
Thanks
Brian

Certificate Based Authentication - Questions and Authentication Modules

Hi Everyone
I'm trying to achieve a specific configuration using AM . I've installed the AM Server 7.1 on a AS9.1EE container and have another AS91EE container on another machine that has the agent configured.
The AM server is using a DS rep for configurations and dynamic profiles and using a AD rep for authentication.
What I now need to achieve is authentication base on one of these two way :
- user and password authentication (which is working)
- Certificate based authentication ( working on it )
To configure the Cert. Auth I've started reconfiguring the containers and agent to work in SSL, as said in the manuals. The manuals also say that the containers must have "Client Authentication Enabled", they don't say which ( either the server or agent container or both ) . Also I assume that "Client Authentication Enabled" is refering to the Http Listener configuration of that container.
When I enable it ( the Client Authentication ) on the http listener for either containers the https connection to that container stops working. In Firefox it simply prompts an error saying that the connection was "interrupted while the page was loading." . On IE, it prompts for a Certificate to be sent to the container and when I provide none, then it gives me the same error as Firefox. In both cases no page was presented.
Basically what I need is for both authentication methods described before to work! So, asking the certificate ( specially if it wasn't the AM asking for it ) without giving the user a chance to use a user/password combination isn't what is wanted.
From what I gathered the "Client Authentication" makes this http listener need a certificate to be presented always .
So, my first question is : is the documentation correct? Does this "Client Authentication" thingy need to be enabled at the listener level?
2- I'll probably need to code a costum module for this scenario I'm working in because of client requisits, but if possible I would like to use the provided module. Still, in case I need to make on, has anyone made a cert. auth module that they can provide me with so I have a working base to start with?
3- Is there a tested how-to anywhere on how to configure Cert. Based Authentication?
All for now,
Thank you all for your help

Hi Rp,
We are using AM 7.1 with Certificate Authentication and LDAP Authentication. To answer your question, yes it is possible to use both method at the same time i.e. Use certificate first and then fallback to LDAP.
First you need to configure AM's webcontainer to accept the certificate. From your message it is clear that you have done that. The only mistake that you did is "made the Client Authentication required". I have done this in Sun WebServer 7.0 and Sun Application Server 7.0 (yeah that is old!!). You need to make the Client Authentication as optional. It means that Certificate will be transferred only when it is available otherwise Web Container will not ask for the Certificate. You will have to search Glassfish website or ASEE 9.1 manual to learn how to make the Client-Authentication Optional. You definitely need this authentication optional as Web Agent will be connecting to this AM and as far as I know they do not have any mechanism to do the Client Authentication.
Secondly, In AM 7.1, you will have to Set up the Authentication chaining. Where you can make Certificate Module as Sufficient and LDAP module as REQUIRED.
Thirdly, if you are using an non ocsp based certificate then change the ocsp checking in AMConfig.properties to false.
Fourth, You may have to write a small custom code to get the profile from your external sources. (if you need to then I can tell you how).
HTH,

ActiveSync with Certificate-Based Authentication

We are trying to setup ActiveSync with certificate-based authentication against Exchange 2010 SP2, but with no luck.
What has been done so far:
OWA over https works fine. A public, trusted certificate is in place.
Setup ActiveSync against this Exchange server: works fine, using user name/password.
Issued a user cert, signed with an internal CA, CA-cert successfully imported into al client devices.
Created a new OWA-site with cert-based authentication (just to make sure it works), imported user certificate into a mac, visit this OWA site - cert-based authentication works fine.
Now, with the configuration utility, created configuration profile with that user cert and an ActiveSync account, left password blank and chose the imported cert (p12) as authentication means.
After installing that last profile the device keeps asking for a password and refuses to synchronize. Logs on the server show error 401.2, so I assume iPhone is ignoring the cert and is trying to use password-authentication instead.
The devices tested were iPhone 3G with IOS 4 and iPad 2 with IOS 5.
Any help will be greatly appreciated.
Roman.

No-one with this experience?
We've done some network analysis (as much as was possible to decrypt) and could see, that the server sends an SSL-Alert (rejection?) to the client after the client presents the certificate.
That explains why the client falls back to password-authentication, but it does not tell us why the server rejects the cert (that is accepted perfectly when accessed from a browser) in first place.

Client certificate based authentication

We have a JAVA web start application that needs to connect to an apache server and use client certificate based authentication. When javaws initiates a connection with apache server, it tries to retrieve the certificate/key from the PKCS12 keystore to present it to the apache server. We have made this work, however, javaws is prompting user to enter the password for accessing the keystore password. We do not want our users to enter this password and are looking into ways to either supply the password as one of the javaws deployment property or create an unprotected keystore. Both of our attempts have been unsuccessfull. We have tried the following
1. we passed the 3 discussed properties (javax.net.ssl.keyStore,
javax.net.ssl.keyStorePassword, javax.net.ssl.keyStoreType) in Java
Control Panel, according to the following procedure: open Control Panel,
select Java tab, click View under Java Applet Runtime Settings, set
values in Java Runtime Parameters table column. This operation added the
properties to the user's deployment file (in a new attribute named
deployment.javapi.jre.1.5.0_09.args, which held all 3 properties as a
value), but there was no effect (password window still popped up).
2. We setup the deployment.property file manually with the 3 attributes
[javax.net.ssl.keyStore, javax.net.ssl.keyStorePassword,
javax.net.ssl.keyStoreType], it didn't have any affect either.
3. When launching java applications you can set system properties as
part of the command line using the follwing format
"-D<property_name>=<property_value>", we failed to find the analogous in
javaws.
Has anyone got any ideas on how to workaround this problem? Really appreciate any help here.

Hi, client cert auth is not realy the best way to protect your resources. It needs to install client cert on every workstation to access application. I think it conflict with javaws concept!
I have the same situation (protect resources and avoid password promt on start) and my solution is:
Using tomcat as web server:
Direct structure as follow:
/ApplicationRoot
       /WEB-INF
             /resources
                    - private.jar
                    - private.jnlp
        /resources
             - icon.png
             - public.jarAs you can see there is no direct access to protected resources. All protected resources availiable only thrue ResourceProvider servlet, configured as follow (web.xml):
<servlet-mapping>
        <servlet-name>ResourceProvider</servlet-name>
        <url-pattern>/resources/secret/*</url-pattern>
</servlet-mapping>
<security-constraint>
        <web-resource-collection>
            <web-resource-name>protected resources awailiable from browser</web-resource-name>
            <url-pattern>/resources/secret/browser/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>somerole</role-name>
        </auth-constraint>
        <user-data-constraint>
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>
        </user-data-constraint>
</security-constraint>
<security-role>
        <role-name>somerole</role-name>
</security-role>
<login-config>
        <auth-method>BASIC</auth-method>
        <realm-name></realm-name>
</login-config>Code your ResourceProvider servlet to grant access only if:
- Connection is secure (ssl).
- URL pattern is "/resources/secret/browser/*" and client has pass realm.
- URL pattern is "/resources/secret/javaws/secretkey/*" (where secretkey is a pin kept both by client and server)
To Install app from browser (access private.jnpl) use "/resources/secret/browser/*" url pattern and basic auth.
To download app resources configure jnlp file as follow:
<jnlp spec="1.0+" codebase="https://host:port/AppRoot/resources/" href="secret/javaws/secretkey/private.jnlp
    <information>
         <icon href="icon.png"/>
    </information>
    <resources>
        <j2se version="1.6+"/>
        <jar href="secret/javaws/secretkey/private.jar" />
        <jar href="public.jar" />
    </resources>
</jnlp>
{code}
And last you need to do is configure ssl connector on tomcat server as follow:
{code}
<Connector port="port"
         scheme="https"
         secure="true"
         SSLEnabled="true"
         clientAuth="false"
         sslProtocol="TLS"
/>
{code}
Pay attention to "clientAuth" param. Set it to "false" to avoid javaws splash cert choose dialog on every app update.
Hope it help!

OWA and ActiveSync certificate based authentication

I have Exchange 2013 CU3 installed and want to activate the certificate based authentication for ActiveSync and OWA. But I want to have the login without certificate as well for users without a certificate.
I already found some information how to do that on Exchange 2010 and I already did all steps to activate it.
But at one point I cant find anything to configure in Exchange 2013. So I have activated the AD certificate based authentication in ISS and configured the OWA folder in IIS to accept client certificates. This seems to work as I get asked to use the certificate
when I open the OWA page. But then I am landing on the OWA login page where I have to enter username and password.
So it seems that I am missing something. In the tutorials for Exchange 2010 they activate the certificate based authentication in the Management console. But I cant find anything in ECP to activate.
Can anyone help me?

Hi,
We can create an additional Web Site in IIS to configure additional OWA and ECP virtual directory for external access. And configuring the Default Web Site for internal access.
Then we can configure internal one with Integrated Windows authentication and Basic authentication while the external one configured for forms-based authentication of Domain\user name format. For more information about
Configuring Multiple OWA/ECP Virtual Directories, we can refer to:
https://blogs.technet.com/b/exchange/archive/2011/01/17/configuring-multiple-owa-ecp-virtual-directories-on-exchange-2010-client-access-server.aspx

Certificate based authentication using amclientsdk

Hi there,
We have written custom authentication framework around the amclientsdk. we are able to use the basic authentication (user/password) service configured in access manager for authentication. But we also like to do certificate based authentication where the user choose the the logon using certificate link and certificate from browser will be preseneted to our custom framework and from there i am using the AM API to invoke Cert auth service.It didn't work and reports User certificate not found error. I don't how to present the retrived user certificate to access manager as there is no call backs for Cert auth service.
Our custom application and access manager are running under different sun web server instance. And both configured for SSL (client authentication not required mode).
I tried changing the access manager instance to SSL client authentication required mode that time it sent 403 error code. but i need the previous scenario to work.

Hi there
I've got to get this working aswell.
In my case I've got to have both the user/password authentication OR certificate based.
The thing is, the documentation says that I need to have the containers (don't know if both the am server and the agent containers or only one of them ) with SSL and "Client Authentication enabled"... now the problem is, when I make it Client Authentication Enabled the container gives me a similar error to the one you described, this is because the server requests the browser to send a certificate when trying to access the server .....
Can you give me any pointers to how this is supposed to be done? I would really appreciate help with this.
Thanks

Exchange 2010 SP3 OWA with certificate based authentication

Hi,
I have a bizarre problem in my customer’s environment. Maybe someone has an idea.
Exchange 2010 with SP3, latest cumulative Update installed.
The problem I’m having is that when I enable Certificate based authentication (require client certificate option in IIS) on OWA and ECP virtual directories in conjunction with forms based authentication (this is the requirement – the user
must have a client certificate and type in username and password to log in to OWA), the result is that after the user selects the certificate he wants to use, he is logged into OWA automatically, but cannot use the website, because it’s being constantly automatically
refreshed (or redirected to itself or something like that). The behavior occurs with all users, with any browser. If client certificate is on required, forms based authentication works just fine. If I switch to “Basic Authentication” and enable client certificate
requirement, then OWA act’s as it should be – so no problems. The problem only occurs when authentication type is forms based and client certificates are required.
I have tried the exact same settings (as far as I can tell) on one other production server and one test server, and encountered no such problems.
Anyone – any ideas?

Hi McWax,
According to your description and test, I understand that all accounts cannot login OWA when select require client certificate.
Is there any error message when open OWA or login? For example, return error ”HTTP error: 403 - Forbidden”. Please post relative error for further troubleshooting.
I want to confirm which authentication methods are used for OWA, Integrated Windows authentication or Digest authentication? More details about it, for your reference:
http://technet.microsoft.com/en-us/library/bb430796(v=exchg.141).aspx
If you select another authentication method, please check whether Client Certificate Mapping Authentication services is installed, and also enabled in IIS, please refer to:
http://www.iis.net/configreference/system.webserver/security/authentication/clientcertificatemappingauthentication
To prevent firewall factor, please try to sign in OWA at CAS server. Besides, I find a FAQ about certificate:
http://technet.microsoft.com/en-us/library/aa998424(v=exchg.80).aspx

How does Certificate based authentication work?

We are doing
Certificate based authentication in an enterprise with android phones and exchange 2010.
We are using activesync to talk to exchange over SSL.
It is working.
I am trying to document HOW it works (on a fairly high level).
I have some information, but would like to know what happens when exchange gets the actual client auth cert from the device in the last part of the authentication process.
Does exchange forward it in toto to AD, since AD (and its related PKI service) created the cert?
Thanks.
Mac

Hi Ainm
Exchange ActiveSync supports several types of user authentication. By default, Exchange ActiveSync is configured to use Basic authentication. This transmits the user name and password in clear text. You can configure Exchange ActiveSync to use certificate-based
authentication. This method uses a certificate on both the server and the device to validate the connection from the device to the server.
There are differences between the mobile operating systems as to what format they like their certificates in, but both Windows Mobile and iPhone are happy to use pfx files whereas Android prefers it as a p12 (which can be just a renamed pfx file if you like).
Certificate based authentication is done via kerberos and yes Exchange should perform the lookup with AD for verifying that your certificate is good and valid.

Certificate Based Authentication and SSL

To whom it may concern,
I have installed SJES on Solaris 9 x386 (intel version). Everything is running fine, the mails are also coming and going.
Now, I need Certificate based authentication and SSL. I have downloaded versign.com trial certificate and have install it succesfully in the Messaging Server Console -- > Manage Certificates. The certificate is also visible in its tab.
Next, I followed the documentation and enable ssl by using ./configutil utility. And also restarted the server.
I am running my Messenger express (http) like this :
http://testing.xyz.com:8100
(I am using port 8100 for http access to mails). After restarting the mail server, I tried :
https://testing.xyz.com:8100 also,
http://testing.xyz.com:443 also,
https://testing.xyz.com:443 also,
but I cannot see the login page of the mail server. All the above mention url i tried and just given error "the connection was refused when attempting to contact testing.xyz.com. I CAN ONLY SEE THE LOGIN PAGE WHEN I WRITE THE OLD HTTP ADDRESS: i.e. http://testing.xyz.com:8100
And I also checked the logs and the server is having no problem in starting and there is not a single word regarding SSL enabling in the logs.
Please help me out, it's really a strange behaviour. I am using SunONE Messaging Server 6.0.
Thanking you,

Dear jay,
I am pasting a line from imap and http logs ... i don't know what this error means and how to resolve it.
[29/Dec/2004:14:42:45 +0100] testing imapd[888]: General Error: SSL initialization error: ASockSSL_Init: couldn't find cert Server-Cert (-8183)
strange thing is that my certificate name is lowercase server-cert and also i can see in the GUI console the certificate name as lowercase and I have also set this parameter encryption.rsa.nssslpersonalityssl = server-cert (all lowercase), but the error in the log tells it as "Server-Cert" !!!! though it is "server-cert"
i got this line from the http log:
[29/Dec/2004:14:42:47 +0100] testing httpd[894]: General Error: SSL initialization error: ASockSSL_Init: couldn't find cert Server-Cert (-8183)
I haven't missed the sslpassword.conf file step. I have placed the same password which i provided while generating the certificate request in the GUI.
Help me out what this errors means and how to resolve them. I have also copied the cert7.db and key3.db to /opt/SUNWms*/config directory from the /var/opt/mps/serverroot/alias
Thanking you,

C4C to CRM integration using HCI Certificate-based Authentication - 403 Forbidden

Hi Experts,
In reference from the discussion in this link (Quick Guide on using Certificates for Integrating C4C and ECC using HCI), we need suggestions on why we're getting 403-Forbidden error, what steps did we miss for our communication from C4C to CRM using HCI.
We already imported the necessary certificates in the iFlows/SSL Server/Client PSEs signed by Entrust (which is one of the supported CAs and our communication from CRM to C4C certificate-based authentication configuration is working fine) for HCI. We also mapped the HCI client certificate to the CRM user that we created (CODINTEG). Service IDOC is also registered and activated (SICF and SRTIDOC).
Below are the roles assigned to the user CODINTEG, and the mapping of HCI client certificate in SM30 and also the certificates imported in our SSL Server PSE. Just a note that we're not using SAP webdispatcher as a reverse proxy here for our C4C to CRM connection.
Thanks in advance.
Regards,
Rajiv

Hello Rajiv,
for test purpose and for eliminating error reasosns caused by user authorization rights you could assign first SAP_ALL to your communication user. If this works, you should reduce the rights again to a minimum...
Goto SU01 and edit the user CODINTEG. Goto Tab Profiles and within F4 help tab "Composite Profiles" search for SAP_ALL.
Best regards,
Berthold

NPS and Cisco ASA 5510 - AnyConnect Certificate based authentication

Hi everyone,
Hoping someone can help please.
We're trying to go for a single VPN solution at our company, as we currently have a few through, when buying other companies.
We're currently running a 2008 R2 domain, so we're looking at NPS and we have Cisco ASA 5510 devices for the VPN side.
What we would like to achieve, is certificate based authentication. So, user laptop has certificate applied via group policy based on domain membership and group settings, then user goes home. They connect via Cisco AnyConnect via the Cisco ASA 5510 and
then that talks to MS 2008 R2 NPS and authenticates for VPN access and following that, network connectivity.
Has anyone implemented this before and if so, are there any guides available please?
Many Thanks,
Dean.

Hi Dean,
Thanks for posting here.
Yes, this is possible . But we have guide about a sample that using Windows based server (RRAS) to act as VPN server and working with Windows RADIUS/NPS server and use certificate based authentication method (Extensible Authentication Protocol-Transport
Layer Security (EAP-TLS) or PEAP-TLS without smart cards) for reference :
