Are shadow passwords enabled? Is /bin/su suid-root and able to read
the shadow file? Does the normal password file contain an 'x' and the
actual password reside in /etc/shadow? That would match the stated
behavior.

Makes me thing the suid-root bit is not set on the su command.
Because login does not use su at all.

I don't think that should be needed.
What errors are recorded in the syslog? On my machine that would be
/var/log/auth.log but on yours it is probably /var/log/messages or
some such.
Also, can you verify the following information?
su --version
type su
ls -ld $(type -p su)
If the above is /bin/su then:
rpm -qf $(type -p su)
rpm -V $(rpm -qf $(type -p su))
