I'm rather stumped about a configuration file issue with pam or ssh or sshd that is preventing me from going to root via su - from a ssh'd in client (windows via putty)

I can su - at the console file, so I know it's a config file someplace.

here is the log entry:

Aug 17 01:58:29 webby PAM-warn[25166]: function=[pam_sm_authenticate] service=[su] terminal=[ttyp1] user=[root] ruser=[Alan] rhost=[<unknown>]
Aug 17 01:58:30 webby su[25166]: pam_authenticate: Authentication failure
Aug 17 01:58:30 webby su[25166]: - ttyp1 Alan-root

I suspect it is related to the rhost=[<unknown>], but I couldn't find anything on that one.
