CWMS Certificate Authority issue

Hi Everyone,
I've an issue with my CWMS Certificate Authority (CA),
I can't login into my CWMS from IPad (public),
error message is "This Certificate is not from a trusted authority".
I can login and join webex meeting from laptop (local and public),
everything is fine if I use laptop,
Error message from IPad attached.
Please advise

Hi Ovindo,
Are you using SSL certificate issued by a public/official Certification Authority or self-signed certs? If you are using SSL certs by a public CA, ensure you uploaded intermediate certs to CWMS as well. Please, take a look at this article for more info: http://www.cisco.com/en/US/docs/collaboration/CWMS/1_5/Troubleshooting_Guide_chapter_01.html#reference_EA8E3F4F2B12484F8433FB7FC4EF018F
I hope this helps.

Certificate Authority Issue, Please help...

I'm writing a program using Java Security APIs and other third party APIs, such as IBM's XSS4J.
The client program do the digital signature on a XML file using a java keytool generated self signed "private DSA key".
The server side program receives the XML and then tries to verify the the digital signature.
The program works fine. However, I've got a question about the Certificate Authority, like Verisign. Because I want to get a more formal private DSA key for doing digital signature instead of using the self-signed key. Does anyone have the experience with that? I checked Verisign's website, and have no idea which of their "product" to choose. Basically, I just need Verisign to sign on my keytool generated private key.
Please tell me how. Thanks a million.

Thanks for correcting me. Actually I want ot send the certificate to Verisign and get it signed there. But how to do that? I checked the code signing, that is for digital signing your program that for other people to download. Not for the XML signing.
I used the command to generate the Digital Signature Key.
keytool -genkey -alias myTourOperatorCertificate -keyalg DSA -dname "CN=Bilal Siddiqui, OU=HotelBookings, O=myTourOperator, C=PK" -keypass myKeyPass -keystore tourOperatorCertificate -storepass myKeyStorePass

Certificate authority Server (Digitial Certificate)

Hi Everyone ,
We are planing to to buy a digital Certificate Manager, which we will be using to issue certificates to our all the cisco routers placed at ATM machines.
so that they can be authenticated and then to be connected via VPN to main branch.
I did some google and found many certificate authority issuing server , like , RSA , Digi-Cert , IBM and many more, i am just confused which one is best to implement here.
Any suggestion will be highly appriciated.

If this is internal and you only need it for devices you controll you can create your own Certificate Authority on Linux/Windows

Certificate Authority chain issue

Hello,
I have a problem with using root and sub Certificates in our PKI environment. Specifically, I have a problem with the way the Java implementation of certificates is working in our environment.
We use Entrust as our external Certificatation Authority. We are a predominantly Microsoft environment and have implemented PKI for user accounts and Smartcard logons across our domain. Our certificates are generated under Entrusts certificatation authority and we have added their DCOMROOTCA and DCOMSUBCA (Root and Subordinate) certificates to our trusted root certification Authorities store for all MS clients. Entrust have recently reissued their DCOMROOTCA and DCOMSUBCA certificates and we have included those new certificates in our trusted root certification Authorities store. The old Entrust certificates are still valid and dont expire for another 2 years. Our PKI environment and authentication continues to work as normal in an MS environment.
In a Windows environment which is using Microsofts implementation of certificates, a smart card which was issued under Entrusts old root certificate will successfully authenticate with a certificate issued under Entrustss new root certificate.
I am having a problem with VMWare View. VMWare View is a Web interface broker server which uses Javas implementation of certificate security, ie uses keytool.exe and cacerts as its trusted certificate store. I have secured the web interface with a certificate issued under Entrusts new root certificate. I am trying to authenticate with a smart card which has been issued with a certificate under Entrusts old root certificate. This has not been successful. I have imported the old DCOMROOT and DCOMSUB certificates and the new DCOMROOT and DCOMSUB certificates into the cacerts file. The client (a Wyse Terminal) also has the old and new DCOMROOT and DCOMSUB certificates in its trusted store. When I attempt to logon I get the following event in the logs on the Web interface broker server:
16:54:18,789 DEBUG <pool-1-thread-17> PooledProcessor SSL handshake exception from /10.42.2.138:2867, error was: sun.security.validator.ValidatorException: Certificate signature validation failed
If I reissue the Smartcard with a new certificate which has been generated under Entrust's new root and sub certificates I am able to successfully authenticate.
The conclusion I can draw from this is that Java certification (at least in the way I have set it up) breaks if a new issuing certificate is being used to generate a certificate to secure the Web interface and an old issuing certificate is being used on a smart card / client.
Does this sound correct? Is this a known issue or have I not imported or setup up the certificate chains correctly?
Any advice would be most welcome.
Many thanks,
Ben

Hi,

Certificate Authority - How to issue Certificates without extensions?

We are operating a Windows 2012 Server PKI with an Enterprise Subordinate Certificate Authority that is issuing Certificates through an AD Certificate Template, however there are certain certificate extensions that need
to be excluded.
We are following the procedure defined in ;
http: //blogs.technet.com/b/pki/archive/2007/01/03/how-to-exclude-the-certificate-template-name-from-certificates-to-be-issued.aspx
certutil -setreg policy\DisableExtensionList +1.3.6.1.4.1.311.20.2
certutil -setreg policy\DisableExtensionList +1.3.6.1.4.1.311.21.7
net stop certsvc
net start certsvc
This does not have any effect as issued certificates continue to have the extensions in them after the change.

Can you confirm that this command contains EDITF_DISABLEEXTENSIONLIST flag enabled:
certutil -getreg policy\editflags
if not, then you should enable it:
certutil -setreg policy\editflags +EDITF_DISABLEEXTENSIONLIST
and restart CA service.

Certificate Authority certificate issued with incorrect hash algorithm

Hi all,
We have a certificate authority which was migrated from Server 2003 to 2008R2, the issue is that after running this command:
certutil -setreg ca\csp\CNGHashAlgorithm sha256
to upgrade the CA to SHA256, we renewed the CA certificate but the certificate still renewed using SHA1. The cryptographic settings in the CA properties dialog box says SHA256 however the certificate is issued using SHA1. Here is the image:
Any pointers to how we can reissue CA certificate with SHA256 algorithm?
Thanks,
Ojas

[Puneet Singh] What i feel is that your initial key which was generated was CAPI based that might be the reason you might be facing the problem.
Try to do the things in below sequence.
certification authority’s system, you will need to run the following commands from an elevated command line window:
certutil -setreg ca\csp\CNGHashAlgorithm SHA256
net stop certsvc
net start certsvc
Make sure you are using a Key Storage Provider that supports SHA256 – for example the Microsoft Key Storage Provider -
and then renew the certification authority’s certificate.
if you have the CAPI provider or you are CAPI based key then you have to convert it to CNG key and use certutil
repair so that it does start using the CNG key.

How do I set up my own certificate authority

I tried google on the above question, and the most recent thing I found was 7 years old. replacing the phrase used generates a lot of hits with a very poor signal to noise ratio.
I have OpenSSL (in the cygwin distribution), which is quite recent, but frankly its documentation leaves just about everything to be desired. I found pyca, but it has no documentation at all (and it is a couple years old).
I tried the steps appended below, but invariably the attempt to sign the certificates fails with an obscure error message about OpenSSL not finding one thing or another.
At this stage, I just don't care whether I do this using something in the J2SDK such as keytool or OpenSSL, as long as I can get it done. Or if there is some other opensource software tool I can use, terrific. This is primarily for the purpose of securing communications within an Intranet, and secondarily for signing applets and applications distributed through WebStart. If I am not mistaken, I'll need a certificate for each of my servers. Right?
If you know of an URL where this is well explained and illustrated, great. Give that to me.
Otherwise, a simple illustration (or a correction of what I've appended below) would be appreciated. I believe I understand what ought to be happening. It ought to be rather simple to do, but there are these irritating and frustrating minor details getting in the way. For example, the steps I show below seem simple, but everything appears to get messed up by some of the contents of openssl.cnf in 'usr/ssl', in the cygwin directory, and there is no explanation of how to set things up for the first time you use OpenSSL within Cygwin (or on unix for that matter).
Any assistance would be appreciated.
Thanks,
Ted

Windows Server 2008 R2 Standard "Certificate Authority Service" / Exchange Server 2010 EMC not starting and no AD connectivity for authentication.

Hello,
I am a new IT Manager at this company and need assistance big time. Their environment looks as follows:
Server 1. Domain Controller Server (Windows Server 2008 R2 Standard) running active directory.
Server 2. Email Server (Windows Server 2008 R2 Standard) running Exchange Server 2010 .
* Note. No back ups to work with aside from whats mentioned below.
DC had a virus infection causing a lot of issues on the shared network drives 2 days ago locking up all the files with a crypto ransom virus. Running Avast suppressed the infection. Had to recover the file shares which luckily had a back up.
The issue is that the Exchange Server 2 post this lost connectivity with the AD Server 1. Exchange Server 2 when launching EMC could not launch the console stating the following:
"No Exchange servers are available in any Active Directory sites. You can’t connect to remote
Powershell on a computer that only has the Management Tools role installed."
Shortly after I found that it is possible the EMC launcher was corrupt and needed to be reinstalled following another blog post. I deleted the exchange management console.msc per instructions only to discover I couldnt relaunch it because there was
no way how. So I copied another msc file that happened to be on the DC Server 1 back to Exchange Server 2 and got it to launch again.
Another post said that it might be an issue with the Domain Account for the Computer, so to delete it in the AD Server 1 only to find that rejoining it from Exchange Server 2 using Computer>Properties> Chage Settings > Change is greyed out because
it is using the Certificate Authority Service.
I tried manually re-adding the computer in AD and modeling permissions after another server in group settings but no go. After this I was unable to login to the Exchange Server 2 with domain accounts but only local admin, receiving the following Alert:
"The Trust Relationship between this workstation and primary domain failed."
I tried running the Power Shell tools on Exchange Server 2 to rejoing and to reset passwords for domain accounts as noted in some other blogs but no luck as the Server 2 could not make the connection with Server1 or other errors it kept spitting out.
I also during the investigation found the DNS settings were all altered on both the Server 1 and Server 2 which I luckily was able to change back to original because of inventorying it in the beginning when I started.
I need help figuring out if I need to rejoin the Exchange Server 2 manually by disabling the Certificate Authority Service (or removing the CA as listed here:
https://social.technet.microsoft.com/Forums/exchange/en-US/fb23deab-0a12-410d-946c-517d5aea7fae/windows-server-2008-r2-with-certificate-authority-service-to-rejoin-domain?forum=winserversecurity
and getting exchange server to launch again. (Mind you I am relatively fresh to server managing) Please help E-Mail has been down for a whole day now!

Untrusted server cert chain & does not recognize the certificate authority

I have java code that makes an ssl connection to an HTTPS server.
The code workes fine when I connect to a server that has a
certificate that was issued by a recognizable authority.
But when I try to connect to our test HTTPS server which has a
certificate that was created by ourselves for debug, I get this
java exception: "untrusted server cert chain".
When I connect to our test HTTPS server with a browser, I get
this message from the browser in a popup window:
"www.xyz.com is a web site that uses a security certifcate to
identify itself. However netscape 6 does not recognize the
certificate authority that issued this certificate."
At this point I am able to accept the certificate in the popup
window and continue.
Question: In my java code how can I accept a certificate
that was signed by an unrecognizable authority just like the
browser can. Or during debug, how can I set an override
to accept ALL certs no matter what.
Thanks.....Paul

You will have to import your server test certificate into your client machine keystore. By default the keystore will be the 'cacerts' file in JAVA_HOME/jre/lib/security, get your server certificate in .pem format and use keytool to import it to the client.
keytool -import -alias <anything> -file <full path of .pem file> -keystore <full path of cacerts file>
The keystore password is 'changeit' by default, keytool comes with the JDK.
The reasoning behind this is to prevent the misuse of test certificates, the client has to consciously import an untrusted certificate. When you install a real certificate on your server the client will be automatically validated if bought from a trusted CA (Thawte, Verisign).
Take a look at the java.security.KeyStore class, you can use it to view your certificate chain.

How to filter certificate templates in Certificate Authority snap-in with the correct values

How to filter certificate templates in Certificate Authority snap-in with the correct values
I have a 2012 R2 server running Microsoft Certificate Authority snap-in.
I want to do a filter on a specific Certificate Template which i know exists in the 'Issued Certificates' folder.
All the documentation i can find seems to suggest i copy the certificate name and use this in the View Filter.
1). I add the 'Certificate Template' option into the Field drop-down.
2). I leave the Operation as the '=' symbol
3). I paste in just the name of the template in question. for example: 'my computers'
The search results always come back blank 'There are no items to show in this view.' even when i know there are many instances of this template. I've tried on a win 2008 server and same issue.
Is there a correct value to enter for the Certificate Template name?
Can this be done easier using certutil commands?
When i run the certutil tool i can confirm i have several issued templates. Certutil -catemplates -v > c:\mytemplate_log.csv
Anybody know what i'm doing wrong?
I seem to be getting nowhere with this one.

> But its important you are using the template name, not the display name
this is incorrect. OIDs are mapped to *display name*, not common name (it is true for all templates except Machine template). That is, in order to translate template name to a corresponding OID, you need to use certificate template's display name. And, IIRC,
template name in the filter can be used only for V1 templates. For V2 and higher, OID must be used.

How to accept certificate authority in HP PPM

How can we accept the Certificate Authority (similar to VeriSign) of any organization specific instead of just accepting the individual certificate in HP PPM.This enables to be able to accept any cert from that organization specific instead of having to import the Certificate each year

How to import a Root Certificate Authority for signing

How can I import a Root Certificate Authority in order to use it with Certificate Assistant as a CA to sign other certs?
I have the CA cert imported in keychain along with it's associated private key (from a .p12), it's got the gold icon and is recognized as a Root certificate authority, yet Certificate Assistant will not list it as an available Root CA in the "Set Default CA" action dialog, the "Add..." dialog seems only interested in a ".certAuthorityConfig" plist file.
Do I have to generate a certAuthorityConfig for the CA? I can't seem to find a way to do that. No clues from certtool & security CLI utils even.
Any info/leads on how to get this to work would be much appreciated.
Regards,
-david

Hi Alex,
From ACE perspective, it doesn't make differences if you are using certificates issued by your local or a "well known" CA. Moreover, if not mistaken, you have to configure authentication group whatever you are doing client or server authentication.

How to find/replace existing certificates before decommissioning certificate authority?

We plan to decommission a multi-use server that also contains our internal certificate authority and replace it with new dedicated CA servers in a more secure design (offline root CA etc.).
Before we decommission our existing CA servers, how do we find a list of all the issued certificates that are still valid?
We would need replace all those old certificates with new certificates from our new CA so the applications that use them don't break when the old certificates are removed/revoked and before we remove the GPO setting that makes our current CA a trusted root
CA for our domain computers.

on CA server you can filter issued certificates by "Certificate Expiration Date" column. In the Certification Authority MMC snap-in, select Issued Certificates folder, then click View -> Filter. Add a filter that would filter certificates
where "Certificate Expiration Date" is greater than current date.

Secured Sybase Web Service with outside certificate authority

Hello,
I would like to use Secured Sybase Web Service with outside certificate authority, like Symantec. Could you let me know how I can create CSR for sending to Symantec? What other steps do I need to do?
Thanks,
Sudarat.

Hello Jason,
Thanks for your reply. The certificate authority require the CSR file before issue a signed certificate. If this is a signed certificate for IIS web server, I can create CSR from IIS. But I cannot use a signed certificate created from CSR of IIS with Sybase Web Service. The below steps are what I have tried.
1. I use CreateCert.exe with /r parameter to create CSR and private key.
2. I sent CSR to a certificate authority and they send back a signed certificate.
3. I have to combine a signed certificate from #2 with private key created from #1. Then use that file to specify with -xs{https …when starting the service.
Are the above steps what I have to do? If so, do I need to redistribute createcert.exe to my customers who want to use my application and how? Why I cannot use the signed certificate created from CSR of IIS?
Thanks,
Sudarat.
