Specifying Windows Authentication - Ricoh SP 4510DN User Manual

• Data transmission between the printer and the KDC server is encrypted if Kerberos
authentication is enabled. For details about specifying encrypted transmission, see page 156
"Kerberos Authentication Encryption Setting".
• During Windows Authentication, data registered to the directory server, such as the login user
name, is automatically registered to the printer. If user information on the server is changed,
information registered to the printer may be overwritten when authentication is performed.
• Users in other domains are subject to user authentication, but they cannot obtain credentials such
as login user names.
• If you created a new user in the domain controller and selected "User must change password at
next logon" at password configuration, first log in to the computer and change the password.
• If the authenticating server only supports NTLM when Kerberos authentication is selected on the
printer, the authenticating method will automatically switch to NTLM.
• If the "Guest" account on the Windows server is enabled, even users not registered to the domain
controller can be authenticated. When this account is enabled, users are registered to the Address
Book and can use the functions available under "*Default Group".
• For the characters that can be used for login user names and passwords, see page 22 "Usable
characters for user names and passwords".
• When accessing the printer subsequently, you can use all the functions available to your group and
to you as an individual user.
• Users who are registered to multiple groups can use all the functions available to those groups.
• Under Windows Authentication, you can specify whether or not to use secure sockets layer (SSL)
authentication.
• To automatically register user information under Windows authentication, it is recommended that
communication between the printer and domain controller should be encrypted using SSL. To do
this, you must create a server certificate for the domain controller. For details about creating a
server certificate, see page 47 "Creating the Server Certificate".
• Under Windows Authentication, you do not need to create a server certificate unless you want to
automatically register user information using SSL.
