That sounds like a problem related to the PAM modules used by
PowerBroker Identity Services.

Please try ftp://ftp.sudo.ws/pub/sudo/beta/sudo-1.8.4rc1.tar.gz and
see if it has the same problem (I expect it will).  If so, add the
following line to /etc/sudo.conf (creating it if it doesn't already

Debug sudo /var/log/sudo_debug auth at trace

The tail end of /var/log/sudo_debug should give me an idea of where
sudo is dying.
