'groups' tells you the groups associated with the current process, which is not necessarily the same as you would get by starting a new session for that user. 'groups ak' tells you the groups that are associated with the user name 'ak' as determined by an /etc/group lookup (or similar action), which is what you would get when starting a new session. Most likely, what happened is that in your testing, you have NOT YET logged out and back in to start a new session. Thus, the current process is STILL associated with testgroup, even though new sessions (and though 'group ak') will no longer be associated with testgroup. Therefore, I'm marking this as not a bug, although you should feel free to provide more details if I have missed something in guessing from your brief description. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
