title: IBM Domino - Which document is unique for Groups
body: <p>Is there a unique document value for each groups inside a <code>names.nsf</code>?</p>
  <p>I would like to add and remove members inside a group over TDI Notes Connector.
  I realize when I choose the <code>ListName</code> as link criteria, there are sometimes multiple lookup results.</p>
  <p>Please note that we do have multiple domino servers. The <code>names.nsf</code> and the groups are replicating, so I'm looking for a document (unique ID) for a group which is not changing on different domino servers.</p>
  <p>Thank you.</p>
