Quest Authentication Services: seperate sudo configs in directory /etc/sudoers.d

Quest Authentication Services -> sudo config

Has anyone figured out how to support Seperate sudo configurations in directory /etc/sudoers.d.  Using sudoers.d is consodered to be best practice.

We recently identified a set of UNIX hosts where an invalid set of rules in a single GPO caused none of the AD sudo rules to be applied to the host, preventing all users from logging via ASU (our company's sudo login tool).  Using a single combined suders file is rather a brittle configuration and not considered Best Practice.

Any thoughts, advice or guidance would be appreciated.
