Failed to login user

Jun 3, 2011 at 11:32 AM


I have all the installation and configurations done and I can add the profile in the LP-App. If I try now to sign in, I'm getting a Sign in failure (The remote server returned an error:Not found). Can anyone help me?

The service needs to be runned under an account with local administrative credentials to be able to read the certificate.

Have you used a server for the chat service that is a trusted server?

Do you have the right certificate?

Is the service account local admin on the machine on which ther service is running?

The chat service runs on the same server like the lync server, so he should trust himself but I also registered the server as a trusted server (so I get the GRUU)


Yes the certificate is the right one and the chat service can read the certificate (I have removed the certificate info in the post above)


Yes the service account is local admin.

I do not think it is a good idea to run on the same server as Lync FE it self.

The server needs to be a trusted app server as described.
