2. Configuring User Authentication
• When SSL is being used, TLSv1 or SSLv3 can function on the LDAP server.
• The LDAP server must be registered in the machine.
• When registering the LDAP server, the following setting must be specified.
• Server Name
• Search Base
• Port Number
• SSL communication
• Authentication
Select either Kerberos, DIGEST, or Cleartext authentication.
• User Name
You do not have to enter the user name if the LDAP server supports "Anonymous
Authentication".
• Password
You do not have to enter the password if the LDAP server supports "Anonymous
Authentication".
For details about registering an LDAP server, see "Programming the LDAP server", Connecting the
Machine/ System Settings.
• For the characters that can be used for login user names and passwords, see page 21 "Usable
characters for user names and passwords".
• In LDAP simple authentication mode, authentication will fail if the password is left blank. To allow
blank passwords, contact your service representative.
• The first time an unregistered user accesses the machine after LDAP authentication has been
specified, the user is registered in the machine and can use the functions available under "Available
Functions" during LDAP authentication. To limit the available functions for each user, register each
user and corresponding "Available Functions" setting in the Address Book, or specify "Available
Functions" for each registered user. The "Available Functions" setting becomes effective when the
user accesses the machine subsequently.
• Transmission between the machine and the KDC server is encrypted if Kerberos authentication is
enabled. For details about specifying encrypted transmission, see page 173 "Kerberos
Authentication Encryption Setting".
Before beginning to configure the machine, make sure that administrator authentication is properly
configured under "Administrator Authentication Management".
1. Log in as the machine administrator from the control panel.
2. Press [System Settings].
3. Press [Administrator Tools].
