Hello,
I am trying to configure the x2gobroker to do key-based login to the servers
after sucessfull authentication against the broker.
Everything looks fine, except the client. It tries to login with the correct
key, but a wrong username. It uses the username from the local machine.
e.g.
- On my local machine, I am logged in as user "martin"
- start the client with --broker-url=http://192.168.0.1:8080/plain/inifile/
- successfully authenticate with the username "udo" and a password against the
broker
- select the session
-> login failed, so I do some research and the auth.log of the remote machine
shows that I try to login with the broker-generated key, but the username
"martin" instead of "udo"
the profile in x2gobroker-sessionprofiles.conf:
[TEST]
user=
host=pegbar1 (192.168.0.1)
name=TEST
command=KDE
fullscreen = true
broker-session-autologin=true
broker-use-load-checker=true
broker-authorized-keys=%h/.x2go/authorized_keys
/var/log/x2gobroker/broker.log shows the key generation for user "udo":

Am I missing some configuration or this this a (known?) bug in x2goclient?
Thank you very much and best regards,
Martin
