Password Manager - What happens when a certificate expires?

Well the answer is lots of errors, some event log entries and a pretty un-usable Password manager solution.
I have just seen this in a customer site where an Internal Certifcate Authority server had been used to create the web certificates for the web interface and password manager servers. The certificates expired after a year and Password Manager stopped functioning.

In order to resolve the issue a new certificate was issued from the CA server and assigned to the relevent servers.
We then needed to resign the data following the guidelines in the following admin guide. Pages 316/317

In simple terms:
1. Create a new certificate.
Run CtxCreateSigningCert.exe from %ProgramFiles%\Citrix\MetaFrame Password Manager\Server folder. Enter the public key file name, the private key file name, and the time, in months, before the signing certificate expires. The new certificate is created.
Example:
ctxcreatesigningcert “C:\PublicKeyCert.cert” “C:\PrivateKeyCert.cert” “36”

2. Resign data at central store using the ctxsigndata command.
Example.
ctxsigndata -r mpmserver.mycompany.com/MPMService "C:\PrivateKeyCert.cert" mycompany.com AD

3. Verify data signatures at central store using the ctxsigndata command.
Example.
ctxsigndata -v mpmserver.mycompany.com/MPMService “https://mpmserver.mycompany.com/MPMService” mycompany.com AD

Done!

If you install HFRP06 onto the Windows 2003 x86 XenApp servers in VMware then when you launch a published desktop you may receive the error.

VMwareUser.exe. The Application failed to initialize properly (0x06d007e).

If you get this then you need to install an additional hotfix available here:

Delivery Services Console Discovery fails.

I have recently updated an existing XenApp 5 farm to FP2 then FP3. As a result of the install the Delivery Services Console fails to discover the XenApp farm.
I tried several remedial actions such as repairing the installation, etc but no fix.
The article from Citrix details the issue and recommends repairing the .Net Framework 2 installation. If this doesn’t work then a process of re-registration of the codebase was required. This is not a very pretty solution.


I found that the cause of the problem was actually a .Net Framework Hotfix.

In order to resolve my issues I simply did the following:
Uninstall KB976576
Reboot
Repair the “Citrix – XenApp Administration”


I hope this helps others who see this issue.
