"Security Token Service is not available" issue when deploing custom c

[pablopecora]

I'm having issues after deploying our custom claims provider (ClaimsProvider.wsp) to a Sharepoint Farm.
(I also include the command line run on the Sharepoint 2010 Management Shell).

We add the solution the ISG Claims provider
Add-SPSolution -LiteralPath “C:\claimsprov\ClaimsProvider.wsp”

And then we try to install/deploy it.
Install-SPSolution -Identity ClaimsProvider.wsp –GacDeployment

Then, the SecurityTokenServiceApplication can not resolve the Active Directory users claims.

The problem appears when we deploy our package:

If we run the Sharepoint Health Analyzer after deploying our provider, we get the following message:
The Security Token Service is not available. ISGSITES2A SPSecurityTokenService (SecurityTokenService)

If we retract (unistall) our solution
Disable-SPFeature -Identity ClaimsProvider_Feature1 -Url

http://SharepointSite:1111

Uninstall-SPSolution -Identity ClaimsProvider.wsp

And re run the Sharepoint Health Analyzer, We can check that the error is gone, and the Active directory recognition gets back to work.

Any clue or help about this?...

Thanks!..
