File permissions on a single NFSv4 client share are mapped to nobody:nobody while the correct user and group exists locally:

       11      20 drwxrwsr-x  2 nobody  nobody      16384 Nov 15  2012 lost+found
148996097   91248 drwxrwsr-x  5 nobody  nobody   93335552 Jul 11 18:40 Statements

In /var/log/messages the following error is displayed:

Jul 15 02:27:54 linux nfsidmap[14274]: nss_getpwnam: name '<$USERNAME>' not found in domain 'localdomain'

The access permissions on other hosts mounting the share show the regular username and group.


Please check the settings in /etc/idmapd.conf on all involved systems to ensure all settings are the same. If this is the case, please run

nfsidmap -c

to clear the cache of the nfsidmap daemon running with the NFS client.


Possible reasons for this behavior are a configuration mismatch or problems with the cached nfsidmap data on the NFS client.
