Description seth vidal 2011-06-22 21:38:39 UTC 
Description of problem:
Hosts setup with matching domain entries in idmapd.conf.
when it hits a file that gets mapped to nobody or is owned by nobody it emits the error:
nss_getpwnam: name 'nobody' does not map into domain

to the logs on the client.

I bumped the verbosity to 9 and talked to steved on irc about it a good bit.
He asked me to file this.

when it hits the nobody files it dumps out this



rpc.idmapd[11066]: nfs4_name_to_uid: calling nsswitch->name_to_uid
rpc.idmapd[11066]: nss_getpwnam: name 'nobody' domain 'fedoraproject.org': resulting localname '(null)'
rpc.idmapd[11066]: nss_getpwnam: name 'nobody' does not map into domain 'fedoraproject.org'
rpc.idmapd[11066]: nfs4_name_to_uid: nsswitch->name_to_uid returned -22
rpc.idmapd[11066]: nfs4_name_to_uid: final return value is -22
rpc.idmapd[11066]: Client 6: (user) name "nobody" -> id "99"
rpc.idmapd[11066]: nfs4_name_to_gid: calling nsswitch->name_to_gid
rpc.idmapd[11066]: nfs4_name_to_gid: nsswitch->name_to_gid returned -22
rpc.idmapd[11066]: nfs4_name_to_gid: final return value is -22
rpc.idmapd[11066]: Client 6: (group) name "nobody" -> id "99"


Version-Release number of selected component (if applicable):
nfs-utils-1.2.3-7.el6.x86_64

How reproducible:
create dir structure - and ls in the mounted dir


 
Actual results:
emits error msg to logs:
rpc.idmapd[11066]: nss_getpwnam: name 'nobody' domain 'fedoraproject.org': resulting localname '(null)'
rpc.idmapd[11066]: nss_getpwnam: name 'nobody' does not map into domain 'fedoraproject.org'

Expected results:
not doing that.


Additional info:

at first we thought it has to do with /etc/nsswitch.conf having entry of:

passwd: db files

but reversing that didn't seem to change things.

The above statement explains the problem. DNS on the local machine was
not set up (or returning NULL) and the Domain= variable in 
/etc/idmapd.conf was  not set. 

I was able to reproduce this problem by setting the Domain=" ".

So I'm going to close this bz, please feel free to reopen it...
