The port number is optional. | | | | Note: It is usually a good idea to use an IP address because it reduces | | risks of failure in the event name service problems. | | | | LDAP server Uniform Resource Identifier: | | | | ldap://dlp.srv.world/_________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ (2) specify suffix +---------------------| Configuring ldap-auth-config |----------------------+ | Please enter the distinguished name of the LDAP search base.
