[mmrraju]

Target ticket-11486

Gluu server user creation process we are using the SCIM 2.0 User Management SCIM2 REST API approach. The user account created successfully in Gluu, but the new user did not receive any welcome emails notifications from the Gluu Server.

The Expected scenario is once the user account created in Gluu over SCIM, User must receive a welcome email with the temporary password or password reset link.
