LDAP Authentication
Specify this authentication method when using the LDAP server to authenticate users who have their accounts
on the LDAP server. Users cannot be authenticated if they do not have their accounts on the LDAP server.
The Address Book stored in the LDAP server can be registered to the machine, enabling user authentication
without first using the machine to register individual settings in the Address Book. When using LDAP
authentication, to prevent the password information being sent over the network unencrypted, it is
recommended that communication between the machine and LDAP server be encrypted using SSL. You
can specify on the LDAP server whether or not to enable SSL. To do this, you must create a server certificate
for the LDAP server.
Using Web Image Monitor, you can specify whether or not to check the reliability of the connecting SSL
server. For details about specifying LDAP authentication using Web Image Monitor, see Web Image
Monitor Help.
• During LDAP authentication, the data registered in the LDAP server, such as the user's e-mail address,
is automatically registered in the machine. If user information on the server is changed, information
registered in the machine may be overwritten when authentication is performed.
• Under LDAP authentication, you cannot specify access limits for groups registered in the LDAP server.
• Enter the user's login user name using up to 32 characters and login password using up to 128
characters.
• Do not use double-byte Japanese, Traditional Chinese, Simplified Chinese, or Hangul characters
when entering the login user name or password. If you use double-byte characters, you cannot
authenticate using Web Image Monitor.
• If using ActiveDirectory in LDAP authentication when Kerberos authentication and SSL are set at the
same time, e-mail addresses cannot be obtained.
Operational Requirements for LDAP Authentication
To specify LDAP authentication, the following requirements must be met:
• The network configuration must allow the machine to detect the presence of the LDAP server.
• When SSL is being used, TLSv1, SSLv2, 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.
