Logout after welcome

[mimi89999]

Hello, When I try to connect to my Windows 7 pro VM, I see the standard welcome loading, but after several seconds the message changes to logging out without me initiating a logout that makes it impossible to login to the remote host.

The warning Protocol(warning): process_pdu_logon(), Unhandled login infotype 1 appears at the same time when the message changes.

Version: 1.9.0-1+b1 from Debian repo

We may be seeing the same with a Windows 10 VM:

$ rdesktop -r sound -r clipboard -r scard -i -o sc-csp-name="Microsoft Base Smart Card Crypto Provider" -u USER HOST -f -p -

With 1.9.0 as well. Remote system reports some errors as well:

I'll note that successful connections result in the 'Protocol(warning): process_pdu_logon(), Unhandled login infotype 1' message, so I don't think that is related.

It seems odd that rdesktop would cause something if you've gotten that far. Does this happen with FreeRDP or Microsoft's RDP client?

[mimi89999]

Actually, I never had this issue in Vinagre

[CendioOssman]

Vinagre uses FreeRDP, so that would indicate that rdesktop is provoking this somehow. Thanks.

In case this information ever helps anyone, I don't experience this issue with rdesktop, but I see similar behavior with OpenSSH when Windows attempts to authenticate my AD account over a proxy network that isn't yet connected. The local system will authenticate me but then the AD will fail to authorize the login because I have no intranet access. I had a different issue (with better log messages) trying to use rdesktop with an AD account before creating a local user by the same name.
