su

[Patrick Dupre]

Hello,

After a fresh installation of fedora 20, I can only log 1 time as a su.
After, it is refused for authentification error!

Maybe a dumb question but, what did you do during the first time that
you were logged in as SU?

Doesn't happen here.  Though I have done yum updates since the install,
a few days ago.  But I don't recall any problems with doing "su" before
I did the updates.  No su run-around....  Sorry, I just couldn't resist.

It might help to see actual error messages.

Sounds like a SUID issue. verify if SUID is set for "su" to run 
with root privileges for common users.
