Within this tab you can change the following global address list properties:
Search Base — the basedn from which the LDAP searches are performed.
Use Alternate User account — if this checkbox is enabled, the global address list uses an alternate user account than the account specified under the Sun Java Enterprise System tab. Enter the User Name and User Password for the alternate account in the appropriate fields.
Anonymous bind — if this checkbox is enabled, LDAP does not authenticate before performing a search. This option is useful for environments that do not have strong access controls. Do not enable this checkbox if your LDAP server requires authentication.
When you are finished making changes, click OK.
