Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition

Specifying a Realm

A realm defines the namespace from which the authentication identity is selected. In DIGEST-MD5 authentication, you must authenticate to a specific realm.

Directory Server uses the fully qualified host name of the machine as the default realm for DIGEST-MD5. The server uses the lowercase value of the host name that is found in the nsslapd-localhost configuration attribute.

If you do not specify a realm, the default realm offered by the server is used.
