[CentOS] nfs question

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
