What could be the reasons for "su root" to not work?

I have a user that's in wheel group. Logging in as root works on the 
console, but su-ing from the user just writes 'Sorry', like the 
password's wrong. There are no clues in log files.

/etc/pam.d/su is identical to another machine where everything works ok.
