Hello,

for some reason, im not able to change to the root user with 'su' although im entering the correct password! I just says 'sorry'...

when i login as root at startup, it works fine...

Does anybody know what's the problem?

Well, I have absolutely no idea because you never posted a distro, a version, software you might be using that affects sercurity. I can lock out su in suse by clicking "Security" and changing it to "Paranoia"

sorry, forgot about that:

Distro: LFS
Kernel: 2.4.23-rc5
Security/login software: GNU coreutils, shadow (using the shadow version of 'su')

While typing this, got an idea: Cause I'm using the shadow su, it could be (in contrast to GNU su which doesn't require this) that I'm not in the same group as root... I'll check that out...

Although that wasn't the problem, I finally found the solution: I changed the permission flags of su from rwx---r-x to rws---r-x...
