I'm trying to diagnose a problem on a CentOS machine in a corporate environment. It's a box someone else configured before leaving the company. The issue is that when we su to the user gitlab, we're actually the user gitauth. There's nothing in /etc or its subdirs that contains the string gitauth. What would cause this? Perhaps an external profile for the user in ActiveDirectory or LDAP? My core question is - what should I look for to point to where the gitauth user is coming from?
[me@blah ~]$ sudo su - gitlab [gitauth@blah ~]$ id uid=398473190(gitauth) gid=398473190(gitauth) ...
Output from authconfig, with org named changed:
