[ActiveDir] Seperate Administrator password policy

[Bahta, Nathaniel V CTR USAF NASIC/SCNA]

Just wanted to field this to see if it makes any sense to any of you guys.    We are going to implement a mandatory 15 character password policy for all of our administrator accounts.  The only way that makes sense is a subdomain with a separate password policy, since there is only one per domain.  I also know that I have to edit the minPwdLength attribute and the uASCompat attribute to make this work on the subdomain.  Can anyone think of another method of doing this?     Thanks,   Nate Bahta
