Hello,

I have problems su-ing to root while I'm running a user account,
I however CAN su to the user while I run root

the user is part of the following groups
wheel,users,portage,cdrom,floppy,cdrw,games,audio,video

when I log in as root:

wilco / # su wilco
wilco@wilco / $ su
Password:
su: Authentication failure
Sorry.
wilco@wilco / $ exit
exit
wilco / #

pam version: 0.77-r1
pam-login version: 3.14
shadow version: 4.0.4.1-r3
sudo version: 1.6.7_p5

I'm running the kernel 2.6.8-rc2-nitro3 under gentoo

I have read about every message on the gentoo forum, but cannot find a solution I also spent a lot of time finding answers on google...

I"m lost, please help me (

Sorry for the silly question, but are you sure the root account has a valid password set up? You haven't posted root's /etc/passwd entry - that would be handy. You would be able to su from root to root without a password setup as su won't check in that situation.

Sudo shouldn't have any relevance (though "sudo su" should work).

hehe, don't laugh please, I feel kinda silly, don't tell anyone but... I kinda errr
mounted the root filesystem with nosuid hihihi.. hehe.. d0h
