[X2Go-Dev] Bug#693: domain users can't open sessions

[Cristian Falcas]

Package: x2goserver
Version: 4.0.1.18

Due to the sanitizer from "/usr/lib64/x2go/x2gosqlitewrapper.pl",
domain users can't login. Usually a login id is in for
"domain\username" or "username at domain". Bot "\" and "@" are stripped
and the sub check_user fails.

Either allow at least "@" as a valid char to username, or make it
configurable and allow extra chars from a varible in the configuration
file.

Best regards,
Cristian Falcas
