Confirmed on ubuntu 14.04 kernel 3.13.0-27-generic with NFSv4 mounts to an Isilon filesystem - even with very high values for the various kernel.keys parameters, we still get sporadic failures for UID/username mappings resulting in user or group IDs on new files showing up as 4294967294 rather than the correct value.
Our LDAP has < 250 users, and I've set these sysctl values on the NFS clients: kernel.keys.gc_delay = 300 kernel.keys.maxbytes = 20000 kernel.keys.maxkeys = 10000 kernel.keys.persistent_keyring_expiry = 259200 kernel.keys.root_maxbytes = 400000 kernel.keys.root_maxkeys = 10000 -- 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
