Sometimes when the user opens the ump page, he gets a login screen on each of the portlets in the page.
1. Wasp checks the Account_, Group_ and User_ tables for the user. If they are not found, or if the password given is incorrect, it goes to the primary hub to find the user and/or re-validate the credentials (in the event of a password change).
2. The hub looks in the nimsoft.dta file to find a Real Nimbus User which matches the login name given to UMP. If none exists it looks at the CM_Contact and CM_Account tables in the NimsoftSLM database.
3. If such a user does not exist in the previous tables and if LDAP integration is enabled, the hub checks the credentials vs LDAP.
4. On a successful authentication the wasp creates a record in tables called Group_ and Account_ and User_ and stores this user's information in those tables.
This is a "Liferay Account" and is completely separate from the others.
