Workflow - Add User to Group

Hi All,

I am trying to create a simple workflow that adds a user to a group in Active Directory (once managers approve). Can someone explain the what the Group Name variable should be if I want to hard code it in as a constant. For instance - do i need to put it in as an LDAP form DC=etc. or just put the name of the group in plain text (e.g. Social Media Users)?

Any help appreciated.  Thanks.
