The user ID and password need not be stored in the repository of the Siebel Analytics server. The external tables and LDAP offer the other possibilites. The userID and password for user authentication are stored in the external table. The information on different tables and the access information for each user are stored in this external table. The other way is the Lightweight Directory Access Protocol. This is similar to imposing a access limitation to all the different directories and folders thereby having the limitations to the data viewable for the different users.
