Identities that do not get fully enrolled for some reason or just need to be expunged to test additional enrollment patterns sometimes seem to get lost but persist in a way that prevents re-enrollment.

Ex: a gmail identity that cannot be re-enrolled
mysql> select actor_identifier,deleted,modified from cm_org_identities where actor_identifier like '%114534390320839864385@google.com%';

Searches for the CO Person or Organizational identity do not find this, however, an attempt to enroll results in an error.  See attachment
