Bug 1409874

I can't reproduce this. Are you sure you didn't click on the "Standard" button (there are two choices: "Standard|Administrator") in the Users control panel applet? It will have that effect.

A few other things strike me as odd:

1. Are you prompted for elevated privileges _immediately_?  That should only happen when you press "unlock".
2. Do you have other admin accounts (members of the wheel group) on this system? AFAIK the app won't let you remove _all_ users.
3. If you remove the current user from the wheel group in this way, there is a popup telling you that you need to restart for it to take effect. Presumably, you didn't see anything like this.

I do get the popup telling me I need to restart, it is there as soon as Users is opened.

That is... curious. That shouldn't happen (and it doesn't, on the two systems I tested it on).

Yes, I am prompted for elevated privileges immediately, even though the button is shown as "unlock" and I have to unlock it before I could make any changes myself.

I am the only wheel user - 

before:

$ grep wheel /etc/group
wheel:x:10:alan-sysop

after:

$ grep wheel /etc/group
wheel:x:10:

Subsequent elevation prompts ask for the password of user "Administrator".  Possibly this is a reference to the root user.

$ grep -i dmin /etc/passwd
alan-sysop:x:1000:1000:Alan Jenkins (System admin):/home/alan-sysop:/bin/bash

The root user is not enabled - there is no password hash for the root user in /etc/shadow, only a "!".

Ok, I started running `rpm -v --all`, and _then_ I noticed hardware errors.

So most likely it's due to bad data from this one drive.

Thanks for looking at my report.

No problem. That's a very weird symptom for hardware errors, but I've seen weirder. :)
