The Gluu Server is a SCIM Server.
We offer a [SCIM client](https://github.com/GluuFederation/SCIM-Client) which can be used to interface with Gluu's SCIM Server.
The Gluu Server is a consumer of identity data. So if you have another SCIM Server, or some application that is doing user enrollment, for instance, you should use the SCIM Client to send data to the Gluu Server.
Does that help clarify?
