Management Based on Authentication and Access Control
Windows Authentication
Specify this authentication when using the Windows domain controller to au-
thenticate users who have their accounts on the directory server. Users cannot
be authenticated if they do not have their accounts in the directory server. Under
Windows authentication, you can specify the access limit for each group regis-
tered in the directory server.
❖ ❖ ❖ ❖ Operational Requirements for Windows Authentication
• To specify Windows authentication, the following requirements must be
met:
• The machine has the scanner function.
• A domain controller has been set up in a designated domain.
• This function is supported by the operating systems listed below. NTLM
authentication is used for Windows authentication. To obtain user infor-
mation when running Active Directory, use LDAP. For this to be possible,
5
the version of Windows being used must support TLSv1.
• Windows NT 4.0 Server
• Windows 2000 Server
• Windows Server 2003
Limitation
❒ Users managed outside the domain are subject to user authentication, but
they cannot obtain items such as e-mail addresses.
❒ With Active Directory, you can authenticate users and obtain user informa-
tion. Under Windows NT 4.0 domain controller, you can only authenticate
users.
❒ If you can obtain user information, the sender's address (From:) is fixed to
prevent unauthorized access when sending e-mails under the scanner func-
tion.
Note
❒ Enter the login password correctly, keeping in mind that it is case-sensitive.
❒ In a network environment with a WINS server, where other networks can be
accessed via a router, you must specify WINS.
❒ If you want to use Windows Authentication, you need to register the user
name that is registered in the Windows server.
❒ Users who are not registered in groups and whose available functions are not
limited in the machine's address book can use the available functions speci-
fied in [Default Group].
❒ Users who are registered in multiple groups can use all the functions availa-
ble to those groups.
