RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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...
