Hello Andrew, in the meantime - after some testing - I found out the problem lies around nfs. I cannot seem to change to directories (placed on nfs-volumes) whose group-member I am. Is this a known problem? Can I do something about it? The situation is: nfs-server 2.4.24 nfs-client 2.6.7 Client knows about 1000 groups and quite a lot users. Mounting some directories from the nfs-server and checking out rights we found that users belonging to a group owning a directory cannot access it. If the exact same tree is located on the clients' local fs everything is fine. Regards, Stephan
