About LDAP/ADSI Security Adapter Authentication

Siebel eBusiness Applications includes security adapters that are based on the LDAP and ADSI standards, allowing customers to use LDAP directory products or Microsoft Active Directory Server (ADS) for user authentication.

In an implementation using LDAP or ADSI authentication, a Siebel-provided security adapter (or another Siebel-compliant adapter) authenticates a user's credentials against the directory and retrieves login credentials from the directory. The security adapter functions as the authentication service in this architecture.

Security adapter authentication provides a user with access to the Siebel application for which the security adapter is configured. Different Siebel applications may be configured to use different security adapters.

LDAP/ADSI Authentication Benefits

LDAP/ADSI security adapter authentication can offer the following benefits:

• User authentication external to the database
• Automatic updating of the directory with new or modified user information entered through the Siebel application user interface by an internal administrator, a delegated administrator, or a self-registering user
• User self-registration
• Registration of users by delegated administrators through the Web site
