Native User Authentication
If the Informatica domain uses native authentication, the Service Manager stores all user account information and performs all user authentication within the Informatica domain. When a user logs in, the Service Manager uses the native security domain to authenticate the user name and password.
If you do not configure the Informatica domain to use Kerberos network authentication, the Informatica domain contains a native security domain by default. The native security domain is created at installation and cannot be deleted. An Informatica domain can have only one native security domain. You create and maintain user accounts in the native security domain in the Administrator tool. The Service Manager stores details about the user accounts, including the user credentials and privileges, in the domain configuration repository.
