Authentication realms manage users and determine user identity within authorization realms for the server.
Users can be created manually or imported from external systems, such as LDAP. Authentication is determined following the hierarchy of realms that is displayed on the Authentication tab. In the following figure, authentication is first determined in the Internal Security realm followed by the LDAP realm. A user who is listed in the LDAP realm can have different authorizations from those in the other realms.
If you have a number of authentication realms, you can reorder them by using the operation tools. Each realm can be moved up to a higher priority, moved down, or deleted by using the operation tools.
For information about authorization realms, see Authorization realms.
- Creating authentication realms
To create an authentication realm on the server, specify where to store information about the users, such as internal storage on the server, a single sign-on service, or on an LDAP server.
- Creating users manually
You can manually create users on the server for internal security and SSO type authentication realms.
- Editing user information manually
You can manually edit the stored name, email address, and password for user accounts on the server for internal security realms. For an SSO authentication realm, name and email address are passed in via HTTP headers (for example, from an HTTP proxy that is translating Kerberos tokens into HTTP headers).
- Importing LDAP users
On the server, LDAP authentication realm users are imported from external LDAP systems.
- Updating LDAP users and groups
LDAP users' name, addresses, and groups can be updated.
