Using the Active Directory command-line tools and the primaryGroupID.bat batch, I have scripted AllUsrSecGrp.bat to display all users security group membership, including nested groups, in a semi-colon delimited format, like:

"User Distinguished Name";"Group Distinguished Name"

The syntax for using AllUsrSecGrp.bat is:

AllUsrSecGrp

AllUsrSecGrp.bat contains:
