To create a user entry in a digest file authentication database, which stores user and group information in an encrypted form, perform the following steps:
Access the Administration Server and choose the Users and Groups tab.
Click the New User link.
Select the digest-based directory service ID from the Select Directory Service drop-down list and click Select.
Enter the following information:
User ID (Required) : Specifies a unique user name for the user.
Realm. Specifies the realm that will authenticate this user.
Password :. Specifies the password for the user.
Password (Again) : Confirms the password entered in the Password field.
Groups: Specifies a comma-separated list of groups of which the user is a member.
Click Create User.
The same realm string must be specified when creating an ACL that uses digest authentication using the Sun Java System Web Server ACL user interface. For more information, see Setting Access Control.
