RDP login problem

[toddpfaff]

I've encountered an interesting problem when trying to RDP login to a Windows 10 system with pGina.fork and the SSHAuth plugin.

1) A "pGina created" user can login at this Windows 10 system's console using SSHAuth.

• ssh server logs shows "Accepted password for ..."

2) A "pGina created" user can RDP login with SSHAuth if and only if that user is already logged in to the console.

• ssh server log shows "Accepted password for ..."

3) If another user is logged in or if nobody is logged in, the RDP pGina.fork SSHAuth login fails.

• ssh server log shows "Failed password for ..."

This is puzzling. Why would an incorrect password be passed to the ssh server by SSHAuth only in case number 3?

Any ideas?
