Active Directory Enabled Logon Scripting

I am looking for a way to write my logon scripts that makes use of the AD OU's. Is there a way to write these scripts for users that are members of OU's instead of members of security groups. for instance, i would like to write a script that says that if a user is in the OU = corporate.acctg then map this drive, instead of, ifmember.exe "ACCTG" (which uses NT Groups), map this drive.

Are the any tools out there that allow you to do this?
