The user is a domain user with standard user rigths (only remote desktop capability).
If i send the cmdlet from powershell connected in RDP it works without problem, when launched in ssh it respond with Access Denied.

It works in SSH only if the user was added to Local Administrators group on the remote machine (SVRTMP).

No repository files or tests are named. Start by reproducing Get-HotFix over SSH and over RDP with the same standard domain user, then compare the session permissions and error details; done means the access-denied discrepancy is explained and covered by an appropriate repository change or test.
