Dear all,
I got NFS4 with GSS running on CentOS 5. Everything is okay, all TGTs are okay and is working fine for the user ROOT.
When I change to an other user, I got a permission denied, when I try to access the dierctory (e.g. ls -la)
Here is the /var/log/messages part for this access (with full debugging on ndf, ndfs and rcp):
