The user names and passwords of registered users are stored
in a user account repository. You can use either the user account
repository of the local operating system (this is the default), the
Lightweight Directory Access Protocol (LDAP), federated repositories,
or a custom account repository.
About this task
The user account repository is the user and groups registry
that the authentication mechanism consults when performing authentication.
Choose a user account repository on the administrative console.
Note: In a network deployment environment, you can use either
LDAP or your local operating system as your user registry.
