Homework and Emergencies Emergency UNIX and Linux Support Accidentally Changed File Ownership to Include a "Comment" [AIX] Post 302711445 by Scott on Saturday 6th of October 2012 10:47:39 AM

Yes, I had a feeling some of the users would need to be re-instated, is why they were tentatively removed.

Just tested on Linux (using RHEL) and it handles it quite differently.

On Linux with only the "commented-out" line in /etc/passwd, ls -l shows me the UID, as I'd expected. If then I add the user back by copying the line and removing the comment, ls shows the username (regardless of whether I put the new entry before or after the commented-out one).

NAME
yppasswdd - configuration file for rpc.yppasswdd (NIS password daemon) SYNOPSIS
/etc/default/yppasswdd DESCRIPTION
The yppasswdd file contains a parameter that modifies the behavior of the rpc.yppasswdd(1M) daemon. The yppasswdd file contains a single parameter: #check_restricted_shell_name=1 By default in the current release, this line in yppasswdd is commented out. If you uncomment the line, when a user attempts to change his default shell using `passwd -r nis -e` (see passwd(1)), the rpc.yppasswdd daemon checks whether the name of the user's current shell begins with an 'r'. rpc.yppasswdd considers any shell whose name begins with an 'r' (for example, rcsh) to be a restricted shell. If a user's shell does begin with 'r', his attempt to change from the default shell will fail. If the line in the yppasswdd file is commented out (the default), the rpc.yppasswdd daemon does not perform the restricted shell check. The yppasswdd file is editable only by root or a member of the sys group. FILES
