Knowing WHY is of course, difficult. As it would have to change the UID on all inodes of all files and directories on the NFS server - under the assumption that the clients have not changed - I would be worried that my server had been hacked
- someone with root access ran a specific chown command (probably together with find)
More likely is that something changed on the clients - and the client definition of user sbladmin
, e.g., if you changed to LDAP and sbladmin has a different uid in that registry than was/is in /etc/passwd.
- In short, the most likely WHY, imho, is a change in how users are identified by the system and in the new "system" uid 42286 is not defined. You can check for one or the other by examining an old backup and verifying what the UID was on old backups compared to what the numerical value is now.
Thanks, Dr. N. I've been using "UID" in my new correspondence with the UNIX team. :) The login never changed so we've got to figure out why it suddently – Al Zuun – 2016-10-21T20:44:08.887
