We are currently trying to fix X2Go logons with AD accounts containing "\" in the username. The concept for email based login, I propose, is: o allow "@" in usernames / session IDs o usernames are 48 chars long at maximum For usernames with backslashes, to do things properly, we need a similar hack like Samba uses (replace the "\" by some other unique symbol. We have some places in the code that detect the username from the session name so the mapping between username and session ID (concerning the username part) should be bijective. We have some hacks for backslashed username in the code (e.g. for fixing #664 [2]), but this actually needs a cleaner implementation. Can you please check/test... (1) How long are email-based logon names? Did they exceed 32 chars? This has been fixed just now for 4.0.1.19 and has been fixed on the master branch for quite a while. (2) Is the email-based logon used as username everywhere on the system (echo $LOGON, echo $USER, echo $HOME)? (3) Does the patch provided here [1] fix your issue for backslashed usernames? (4) Is logon for backslashed users possible if you have x2goserver 4.1.0.0-preview (nightly builds) installed?
