Certificate based authencation logs

We do have have certificate based authentication enabled using SCEP Profile which gets authenticated with one of our Win2K8 Certificate Server using root certificate. Do we have any option to check somewhere in the ISE logs to see if our users are using certificates to authenticate in the network.
In our current logs, we do not see anywhere which concludes that certificates is being used.

Since I'm using workgroup servers and certificates, I tested the commands manually to observe the output, modifying the steps that require certificatethumbprint as a mandatory parameter. I did not get success on this first attempt, but I will keep
trying over the next few days as I have time.
Thank you for the exemplary script. It does indeed reveal at least one missed step, such as completing failover, which was necessary to prevent the set-vmreplication from being blocked by the VM's current state.
In my manual execution, setting the primary as replica had to be performed on the primary after coming back online, at which point both the primary and the replica degenerated to a mutual replica state. I didn't spend much time trying to correct this
condition in powershell, but in Hyper-V management I was able to re-establish replication, although it keeps pausing on the new existing primary (now replica) and the replica (now primary) doesn't indicate replication as being paused.
I will most likely need to remove replication from the VM and start over.
It appears that native Windows authentication (matching usernames and passwords) and certificates will be required to successfully reverse replication. Ultimately, since I will use a service account to enact the role reversal, I tested with a local
admin that did not exist on both systems. Setting the AsReplica in Set-VMReplication appears to use RPC as the command failed with a permission denied error.
I will append my findings. You've given me a great starting point.

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 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.

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:

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.

OCSP Validation in Certificate-Based Authentication

Hi,
Has anybody done OCSP Validation in Certificate-Based Authentication ? If yes - then please describe how can we configure an OCSP responder for Certificate Validation?
Regards,
YK

Hi,
Thanx for all of ur replies :)
I am now able to do lot of stuff using Identity Server :)
My main target is to use Identity Server for certificate-based authentication by enabling OCSP validation.
First I configured Web server to enable SSL and client authentication. Then I configured Identity Server and enabled the Certificate based authentication. I edited the certificate authentication properties and enabled the OCSP validation check. I provided the OCSP responder address and corresponding CA name in AMConfig.properties.
Now I am testing this setup up as follows.
1- I try to access the default index page by following URL
https://identity-1.identity.com:58090/
2- It asks for client certificate to choose from available certificates
3- I select a certificate (issuer of this cert is configured for OCSP validation) and proceed
4- Identity Server make an OCSP request and send it to my OCSP responder
5- OCSP responder response with revocation status 'good'
6- Now I get the server certificate on browser
7- I press OK and I see the index page of Identity Server
I think it is working fine now :)
now if in step 3, I select a wrong certificate i.e. issuer of this certificate is not configured for OCSP validation then It shows the DNS Error Page. Why dont it show the proper authentication failed page of Identity Server? If I see the error log for the web server I see the following error:
[03/Jun/2003:11:18:10] failure ( 1692): Error receiving connection (unable to map error number -8062)
What does it mean ? Any ideas ?

DPS attempting certificate based authentication with Directory Servers

I'm running DPS 6.3 and DS 6.3.
I have DPS configured to always connect to the directory servers over SSL. This is working, however, all of the Direectory server error logs are showing certificate based bind attempts originating from the DPS. This results in err=32, since the certificate isn't stored in the ldap server. Anyone else seeing this type of behavior?
I checked the DPS Security config, and under the "Certificate to use with Data Sources" I have it set to 'None'.
Thanks.

Hello,
Certificate-based authentication cannot be proxied (it was designed to prevent man-in-the-middle attacks).
When the proxy receives a certificate-based bind (SASL EXTERNAL authentication method), it first validates the client certificate (signature, validity,trust etc), and map the certificate identity (subject) onto a LDAP identity. This is done by doing some LDAP lookups against the directory server. Then, that LDAP identity is used for subsequent LDAP requests to the directory servers. As the password is not available, the proxy must be configured to contact the directory server using proxied authorization method or using fixed credentials (used in conjunction with acis set on the proxy)
DPS 6.3 never uses the SASL/EXTERNAL (certificate-based) authentication method when it contacts directory servers.
When SSL is used between the proxy and the server, the proxy may present its own certificate to the directory server (controlled by the DPS security property you mentioned). It is possible to check if DPS stashes its own certificate when it establish a SSL channel to the directory server by using the ssltap tool [http://www.mozilla.org/projects/security/pki/nss/tools/ssltap.html] . If a certificate is passed, the No-Such-Object error you see might be generated during certificate validation by the directory server.
Hope this helps

Make certificate-based wireless unavailable at login?

Error: "Unable to log in with a network account" appears because the wireless connection goes offline. WEP networks work okay, but our internal network uses wireless with EAP certificate-based authentication. Since the Macbook does not come with ethernet jack, I have no other option. How do I get it to connect to the wireless prior to login?

Certificate-Based Client authentication slowness (DSEE 6.3.1)?

I seem to be seeing very slow operations involving certain certificate-based client interactions.
I have a user with an application that connects via LDAPS (port 636), does an anonymous bind, and then binds as a specific user. This application is written using .Net (System.DirectoryServices.Protocols library) and housed on an IIS web server that has a certificate signed by Equifax.
The application performs relatively quickly (operations take an elapsed time of less than 1 second) if:
1. "Client Authentication" is set to "Allow Certificate-Based Client authentication" and there is no Equifax CA cert in the list of CA Certificates.
or 2. "Client Authentication" is set to "Do Not Allow Certificate-BAsed Client authentication".
If I have "Allow Certificate-Based Client authentication" and the Equifax CA cert installed, all operations by the application succeed but show an elapsed time of about 13-14 seconds.
The Equifax CA cert should be trusted (certutil shows flags: CT,, )
Has anyone seen anything like this? I've not been able to successfully figure out how to get additional logging RE: the certificate exchange other than grabbing the raw data from ssltap (which I'm not sure I correctly understand). I turned up the infolog levels to include connection managment and packets, but that didn't provide what I was looking for.

The only thing I can think of off the top of my head is if the server is doing a callout to an external site for something like a CRL. Even though the traffic is encrypted, you should be able to see something like that in a packet trace even so.

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:

[IMAP SSL] Certificate-Based Login problems

Hi,
I am trying to set up a Certificate-Based Login authentication for an installation of Java Messaging Server 7 Update 3 over Solaris x86 64bit platform.
The objetive is to allow a client to establish an SSL session using a certificate that has been issued by a CA that the server has established as trusted and then grant access to the user without providing his password.
In my installation, unfortunately password is allways required to login any user. These are the steps I have made:
1. Add the CA-signed server certificate.
2. Add the trusted Certificate Authority.
3. Turn on all cipher suites including the weak ones.
4. Enable SSL
./configutil -o service.imap.enablesslport -v yes
./configutil -o service.imap.enable -v 1
./configutil -o service.imap.sslport -v 993
./configutil -o service.imap.sslusessl -v yes
./configutil -o encryption.rsa.nssslpersonalityssl -v "Product-Cert" (where Product-Cert is my CA signed server certificate)
5. Check with the netstat command to verify that the service is running.
bash-3.00# ./configutil -o service.imap.sslport
993
bash-3.00# netstat -an | grep 993
*.993 *.* 0 0 49152 0 LISTEN
Once I have taken these steps, when I use a client to establish an SSL session with a PKCS#12 certificate installed (signed by the same CA trusted by MS and the email address in your users' certificates matches the email address in a users' directory entry) the connection is correct stablished using the port 993 but it is allways necessary to login with password to grant access.
The imap logs seems to show that the MS is not requesting the user's certificate from the client, because allways shows "plaintext authentication" (this correspond a try to access to the user's inbox without Login).
[10/Mar/2010:10:31:38 -0100] goody imapd[2623]: Account Notice: badlogin: [192.168.169.12:1595] plaintext llcc authentication failure

Please, Can you help me to discover if there is something wrong in my configuration?
Thanks in advance.

Thanks for your reply Shane.
Yes, I have configured the client to use port 993. I think the problem is in the Multiplexor configuration, after finished, I allways get this Log message in the ImapProxy Logs:

Where 192.168.169.108 is the IP of the server where MS is installed. The strange thing is that there are no connections established becacause this is a development environment, when I try to check the IMAP port (not ssl) I find a strange behaviour:

Any idea?
One question more. I have read that Store Administrators have proxy authentication privileges to any service (POP, IMAP, HTTP, or SMTP), which means they can authenticate to any service using the privileges of any user. The question is: Is there any way for the Store Administrator to access to the mailbox of all the users using the IMAP protocol?
Thanks a lot for your help,

Configuring Certificate-Based Login on iMS 5.2

Dear All,
I have two message stores and one messenger express running on a third server in proxy mode. I am trying to configure the third server to accept certificate-based logins. I have already installed a server certificate, CA certificate, and root CA certificate on this server.I am not planning to install any certificates on the message stores. I have modified the certmap.conf file accordingly to my requirements. The question is, how do I store a user's certificate in LDAP so that the Messenger express which is in proxy mode could use it to authenticate the user?
Currently, I am getting this error in the messager express log files.
General Information: search_from_namespace(uid=marwan,ou=people,o=domain.net.ae,o=eim): no entry
Although the DN exists in LDAP.
Thanks,
Marwan

You will want to look at the ldap server's Access log, and make sure that you've updated the correct record, that it's searching for where you've placed the cert.

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.

Need Help about Certificate based Authentication

Hi friends..
Currently, i'm trying to develop an applet that using Certificate Based Authentication..
i have looked at this thread : http://forums.sun.com/thread.jspa?threadID=5433603
these is what Safarmer says about steps to generate CSR :
0. Generate key pair on the card.
1. Get public key from card
2. Build CSR off card from the details you have, the CSR will not have a signature
3. Decide on the signature you want to use (the rest assumes SHA1 with RSA Encryption)
4. Generate a SHA1 hash of the CSR (without the signature section)
5. Build a DigestInfo structure (BER encoded TLV that you can get from the PKCS#1 standard) that contains the message digest generated in the previous step
6. Send DigestInfo to the card
7. On the card, the matching private key to encrypt the DigestInfo
8. Return the encrypted digest info to the host
9. Insert the response into the CSR as the signature
Sorry, i'm a little bit confused about those steps.. (Sorry i'm pretty new in X509Certificate)..
on step 4,
Generate a SHA1 hash of the CSR (without the signature section)
Does it mean we have to "build" CSR looks like :

How DigestInfo structure (BER encoded TLV that you can get from the PKCS#1 standard) looks like?
And what is the DigestInfo Contains, and what is TAG for DigestInfo?..
Please help me regarding this..
Thanks in advance..

Sorry, Encode the Public Key is handled by On Card Application or Off Card Application?..
I think its' easier to encode the public key by Off Card app..
Could you guide me how to achieve this?, i think Bouncy Castle can do this, but sorry, i don't know how to write code for it.. :( All you need to do is extract the modulus and exponent of the public key. These will be in a byte array (response from your card) that you can use to create a public key object in your host application. You can then use this key to create a CSR with bouncycastle.
I have several some questions :
1. Does Javacard provide API to deal with DER data format?JC 2.2.1 does not buy JC 2.2.2 does, however I believe this is an optional package though. You can implement this in your applet though.
2. Regarding the Certificate Based Authentication, what stuff that need to be stored in the Applet?..
- I think Applet must holds :
- its Private Key,
- its Public Key Modulus and its Public Key Exponent,
- its Certificate,
- Host Certificate
i think this requires too much EEPROM to store only the key..This depends on what you mean by Certificate Based Authentication. If you want your applet to validate certificates it is sent against a certificate authority (CA) then you need the public keys for each trust point to the root CA. To use the certificate for the card, you need the certificate and corresponding private key. You would not need to use the public key on the card so this is not needed. You definitely need the private key.
Here is a rough estimate of data storage requirements for a 2048 bit key (this is done off the top of my head so is very rough):
~800 bytes for your private key
~260 bytes per public key for PKI hierarchy (CA trust points)
~1 - 4KB for the certificate. This depends on the amount of data you put in your cert
3. What is the appropriate RSA key length that appropriate, because we have to take into account that the buffer, is only 255 bytes (assume i don't use Extended Length)..You should not base your key size on your card capabilities. You can always use APDU chaining to get more data onto the card. Your certificate is guaranteed to be larger than 256 bytes anyway. You should look at the NIST recommendations for key strengths. These are documented in NIST SP 800-57 [http://csrc.nist.gov/publications/PubsSPs.html]. You need to ensure that the key is strong enough to protect the data for a long enough period. If the key is a transport key, it needs to be stronger than the key you are transporting. As you can see there are a lot of factors to consider when deciding on key size. I would suggest you use the strongest key your card supports unless performance is not acceptable. Then you would need to analyse your key requirements to ensure your key is strong enough.

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 with SSL load balancer

I've been asked to implement certificate-based authentication (CBA)
on a weblogic cluster serving up web services. I've read through
Chapter 10 (security) and understand the "Identity Assertion" concept.
Environment:
Weblogic 8.1 cluster fronted by a load-balancer that handles SSL and
uses sticky-sessions.
Question:
If the load balancer is used to handle SSL, do I still need to turn
on SSL on the weblogic cluster in order to use CBA? Is there another
way to request the client's certificate?
If the above is yes, what is the minnimal level of SSL? Does it have
to be two-way?
If SSL has to be turned on is there any reason to use the load
balancer's SSL? Is there still a performance benefit?

I think the simplest and most secure way is to have the servers configured for
2-way ssl, since this would ensure that the certificate they receive and use for
authentication has been validated during the ssl handshake. In this case the load
balancer itself does not need to and cannot do the handshaking, and would need
to pass the entire SSL connection through to the WLS server (ie: act similar to
a router)
