You have created a database user e.g. SIE_USR that is going to be used for anonymous login to perform various tasks. All the proper roles and privileges have been assigned to it but still it is not working.
Solution:Whenever you create a database user you have to create corresponding user profile to it. Every user that has to login through Object Manager needs to have its user profile created in Siebel. If user profile for that database user doesn’t exist that user will not be able to login to Siebel through object manager.You can create user profile by going to
Administration User ==> Employees View
In next post I will present a case study where we had to create database user and faced the problem mentioned above after forgetting the user profile creation of that user.
