Hello!

We have central ldap for users, idmapd.conf configured on every machine and users’ home folders on nfs, mounted by automount on several machines.

After the last OS upgrade we notice that permissions on some files (not for all users) are corrupted:

For example:
-rw-r–r– 1 4294967294 4294967294 45 Nov 11 21:20 hostlist drwx—— 2 4294967294 4294967294 4096 Jun 27 2012 .ssh
-rw-r–r– 1 4294967294 4294967294 0 Aug 28 2013 test
-rw-r–r– 1 4294967294 4294967294 53 Jan 6 12:44 test.sh

instead of:
-rw-r–r– 1 ops001 ops 45 Nov 11 21:20 hostlist drwx—— 2 ops001 ops 4096 Jun 27 2012 .ssh
-rw-r–r– 1 ops001 ops 0 Aug 28 2013 test
-rw-r–r– 1 ops001 ops 53 Jan 6 12:44 test.sh

Kernel used: 2.6.32-431.11.2.el6.x86_64
Nfs version: nfs-utils-1.2.3-39.el6.x86_64

User/group mapping works fine. Same behaviour appears when I mount the home folder manually.

Any ideas?
Thanks, Barbara
