Description José Eduardo Martins 2013-08-31 20:53:06 CEST

Description of problem:

One Partition mounted via nfs4 wish have over 200 users shows wrong userid/groupid.

If I try this workaround:

echo 400000 > /proc/sys/kernel/keys/root_maxbytes
echo 10000 > /proc/sys/kernel/keys/root_maxkeys

The problem is fixed.

Version-Release number of selected component (if applicable):


How reproducible:

Mount via nfs4 one partition (/home) wish have a number of users over 200.

$ ls -l /home
