Hello,
We have the following setup:
- an opensuse 12.2 server machine running nis and nfsserver
- a lot of opensuse 11.4 client machines also running nfsserver
- a few opensuse 12.2 client machines (with nfsserver)
All machines can mount each other using autofs. The problem occurs
when an 11.4 machine is nfs-mounting a directory from a 12.2 machine.
What happens is the common nobody problem where a users name
and group becomes "nobody nobody".
It works well the other way around, namely if a 12.2 machine nfs-mounting a
directory of a 11.4 machine. 11.4 -> 11.4 and 12.2 -> 12.2 works naturally.
All machines have identical /etc/idmapd.conf files! One can see the problem
occurring in the idmapd log files:
Here I'm (auto) mounting a 12.2 directory from a 11.4 machine
st02:~ # ls -l /home/bob
total 24
drwx------ 2 nobody nobody 16384 Jan 16 16:03 lost+found
drwxr-xr-x 161 nobody nobody 8192 Jan 24 17:13 mattias
Some log info:
Jan 24 21:49:24 st02 rpc.idmapd[17968]: nfs4_name_to_uid: calling nsswitch->name_to_uid
Jan 24 21:49:24 st02 rpc.idmapd[17968]: nss_getpwnam: name '1014' domain 'localdomain': resulting localname '(null)'
Jan 24 21:49:24 st02 rpc.idmapd[17968]: nss_getpwnam: name '1014' does not map into domain 'localdomain'
Jan 24 21:49:24 st02 rpc.idmapd[17968]: nfs4_name_to_uid: nsswitch->name_to_uid returned -22
Jan 24 21:49:24 st02 rpc.idmapd[17968]: nfs4_name_to_uid: final return value is -22
Jan 24 21:49:24 st02 rpc.idmapd[17968]: Client 4c58: (user) name "1014" -> id "65534"
The '1014' is the userid of the user. Can it perhaps be a nis problem?
Now (auto) mounting a 11.4 directory from the same 11.4 client machine
st02:~ # ls -l /home/beckett
total 28
drwx------ 2 root root 16384 Feb 19 2007 lost+found
drwxr-x--- 10 ster users 4096 Sep 18 18:17 ster
Jan 24 21:53:51 st02 rpc.idmapd[17968]: nfs4_name_to_uid: calling nsswitch->name_to_uid
Jan 24 21:53:51 st02 rpc.idmapd[17968]: nss_getpwnam: name 'ster@localdomain' domain 'localdomain': resulting localname 'ster'
Jan 24 21:53:51 st02 rpc.idmapd[17968]: nfs4_name_to_uid: nsswitch->name_to_uid returned 0
Jan 24 21:53:51 st02 rpc.idmapd[17968]: nfs4_name_to_uid: final return value is 0
Jan 24 21:53:51 st02 rpc.idmapd[17968]: Client 4c5c: (user) name "ster@localdomain" -> id "2007"
Here it works as it should!
To see if it was a problem with different versions of "relevant" packages I have upgraded
nfs-kernel-server, nfsidmap, autofs and ypbind on the 11.4 machine to match the versions
on the 12.2 machines, but the problem remains.
Any suggestions?
