The Active Directory Add User(s) To Group action allows you to add one or more existing users to an Active Directory Group.
Users
Users can be specified as LDAP Distinguished Names, or any valid username format - including simple usernames, Domain\UserName syntax, or User@Domain syntax. The LDAP://domainName/ prefix can be used as well.
Click the Add User(s) button to display a dialog allowing you to search for one or more users to add to the list.
Tip: To add all of the users from one group into another, use the %VarName% syntax.
Group
Specify the name of the group to add users to. Groups can be specified as a simple group name or an LDAP Distinguished Name.
Fail if any users are already members of the group
Check this box to fail the action if any users are already members of the group. If the action fails for this reason, some other users may have already been added to the group.
Credentials (Optional)
You can choose to specify a username and password to use when connecting to the Active Directory. If no username is specified, the current Windows credentials will be used.
