can't use su, "Permission Denied"

I seem to be having complications on my Gentoo System. i cannot use su
as anything other than root...here's the console output...

xero@localhost ~ $ su
Password:                   #typed the correct password
su: Permission denied
Sorry.

i can login as root just fine, so i don't see any reason why this
shouldn't work ...do i need to be in a certain UID range or be in a
certain group to su?

all help appreciated

Yes, you need to be a member of the 'wheel' group.

gpasswd -a [yourusername] wheel

should do the trick - you need to be root to do this, of course

Hope this helps,
Walter

The su will switch user to any if you type user ID after su.
If there is no ID than it is the same as "su root".
For more information please refere to "man su".

That's great - but that's not the problem the original poster is having.
GNU 'su' allows any user to 'su' to root. Operating systems that follow
the Berkeley security model (*BSD and Gentoo being examples) require that
the user must be in the 'wheel' group to use 'su'. Other Linux distributions
can be configured so. If you have set a group password for wheel users,
then a normal user must have the group password to use the 'newgrp' command
to join the wheel group, and the root password to then use su.  Thus, even
if you somehow obtain the root password, it's not enough to use 'su' (though
you could just log in as root if that is permitted - leaving a paper trail
as you do so).
