The Service Manager authenticates users who log in to application clients.
The first time you log in to an application client, you enter a user name, password, and security domain. A security domain is a collection of user accounts and groups in an Informatica domain.
The security domain that you select determines the authentication method that the Service Manager uses to authenticate your user account:
Native. When you log in to an application client as a native user, the Service Manager authenticates your user name and password against the user accounts in the domain configuration database.
Lightweight Directory Access Protocol (LDAP). When you log in to an application client as an LDAP user, the Service Manager passes your user name and password to the external LDAP directory service for authentication.
