Change user's default group on login

[daljitsingh]

When I login to a Solaris 2.8 machine my default group is taken as my primary group from /etc/passwd. Can I automatically override this in any way, e.g. have an entry in my login shell or .cshrc profile ?
I have tried placing "newgrp staff" in my .cshrc file but I get "newgrp: Sorry" when I login and this loops continuosuly.

I know I can manually use the newgrp command but I would like this to be part of the login process.

Thanks in advance

Why don't you just change your group in /etc/passwd and /etc/group?

 

[daljitsingh]

Not permitted to do so - its the way my profile is set by our admin folk and we cannot change the primary group assigned !!

Is the group staff in the list of groups you belong to?

 

[daljitsingh]

Yes, I am a member of group staff.
