invalid group id redhat linux as 5

[wvsa]

Good morning all;

Have encountered a strange problem, on our redhat AS 5.1 server all of the group id's are invalid, the permissions on all the directories for root is root:0 as a matter of fact all group id's on the server are numeric even though the groups are in /etc/group. When I try to change a group id I get invalid group even though the group is in the group file.

Has anyone seen this? Any input would be greatly appreciated.

Maybe the /etc/nsswitch.conf file was modified and is not able to map the group IDs. Check if you have something like this in nsswitch.conf:

group: files ldap

Hello Ivan;

That was it, I had fat fingered nsswitch.conf

Thank you for the quick response.
