Jean,
Delphix users are stored in a database on the Delphix Engine. There is no public interface to allow TIM to manage them directly, but we can authenticate against an external LDAP/AD service, wherein you could manage users via TIM. Within Delphix it will still be necessary to configure each user in order to assign rights to sources, VDBs, and groups, or Delphix Admin rights.
Thank you,
Michael
