Check whether the target object is a member of multiple groups

The scripts can be used in business rules, custom commands and scheduled tasks to check group memberships of an AD object the script is executed on. The script must be executed in the If PowerShell script returns true condition.

The 1st script returns True if the object is a member of all the specified groups
The 2nd script returns True if the object is a member of any of the specified groups

To use them in your rule, command or task, add the If PowerShell script returns true condition that runs one of the scripts.

Return true if the target object is a member of all the groups

Parameter:

$groupDNs - Specifies a list of distinguished names (DNs) of the groups to check.
