I am one of the thin client user in my office.
I often do ssh from other machine to access my /home/vinoth account, when I open thunderbird it gives me the following error.

X11 connection rejected because of wrong authentication.

(thunderbird-bin:22237): Gtk-WARNING **: cannot open display: localhost:12.0

Have you tried running the "ssh" command with the "-X" flag? You should really consult your systems administrator, if you have any problems with your at-work network.

Yes I am executing ssh command with '-X' option.

Have you been able to do this from other workstations? It may be something with the particular version of OpenSSH (if the server you are trying to connect to is using OpenSSH), as noted here.

Alternately, there is a setting in the /etc/sshd/config file that only lets X11 forwarding happen within a specific time limit from the initial connection, which would require the systems administrator(s) to change.
