I was encountering the very same problem in an identical environment (nfs4 and LDAP based nameservice) but on DEBIAN (!). Since I was not able to find any relevant bug reports within the Debian bug tracking system, I was very delighted to find someone having the same problem and reporting it here.
Following this and another bug report I found at RedHat (https://bugzilla.redhat.com/show_bug.cgi?id=876705), I placed the following kernel parameters configuration: in /etc/sysctl.d/nfsv4_idmap_maxkeys: # NFSv4 idmap entries are counted against a very low quota # https://bugzilla.redhat.com/show_bug.cgi?id=876705 kernel.keys.root_maxkeys = 1000 kernel.keys.maxkeys = 1000 After activating that with sysctl the problem was gone with my installation. ** Bug watch added: Red Hat Bugzilla #876705 https://bugzilla.redhat.com/show_bug.cgi?id=876705 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1124250 Title: Partially incorrect uid mapping with nfs4/idmapd/ldap-auth To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1124250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
