Preparing the Server to Use for User Authentication
When using Windows authentication or LDAP authentication as the user authentication method for the first time, check that your server environment meets the requirements for user authentication, and configure the required settings.
To use Windows authentication
Prepare the server as follows:
Check the requirements of Windows authentication.
Install the Web server (IIS) and the "Active Directory Certificate Service" in the server.
Create a server certificate.
You do not need to create a server certificate to transmit user information that is not encrypted.
To use LDAP authentication
Check the requirements of LDAP authentication, and configure the settings according to the server environment as necessary.
Requirements of Server Authentication Used for User Authentication
Items | Explanation |
|---|---|
Usable OS | Windows Server 2008/2008 R2/2012/2012 R2/2016/2019
|
Authentication method | Supports the following authentication methods:
To specify Kerberos authentication, the server authenticating users must support Kerberos authentication. If the server does not support it, NTLM authentication is automatically selected. |
Requirements for authentication |
|
The server can authenticate users managed in other domains, but cannot obtain information such as an e-mail address.
When Kerberos authentication is enabled, the e-mail address cannot be obtained if SSL/TLS is specified.
Even if you edit an authenticated user's information, such as an e-mail address, in the machine's address book, it may be overwritten by the information from the server when authentication is performed.
If you created a new user in the domain controller and selected "User must change password at next logon" at password configuration, first log on the computer and change the password.
If the "Guest" account on the Windows server is enabled, users not registered in the domain controller can be authenticated. When this account is enabled, users are registered in the address book and can use the functions available under [*Default Group].

Authentication method |
When you select Cleartext authentication, LDAP simplified authentication is enabled. Simplified authentication can be performed with a user attribute (such as cn or uid) instead of the DN. |

Notes when LDAP server is configured using Active Directory
When Kerberos authentication is enabled together with SSL/TLS, the e-mail address cannot be obtained.
Anonymous authentication might be available. To improve security, set anonymous authentication to Disable.
Even if you edit an authenticated user's information, such as an e-mail address, in the machine's address book, it may be overwritten by the information from the server when authentication is performed.
Under LDAP authentication, you cannot specify access limits for groups registered in the server.
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.
Under LDAP authentication, if "Anonymous Authentication" in the LDAP server's settings is not set to Prohibit, users who do not have an LDAP server account might be able to access the server.
When using the machine for the first time, the user can use "Available Functions" specified in [User Authentication Management].
To specify "Available Functions" for each user, register the user together with "Available Functions" in the address book, or specify Available Functions in the user registered automatically in the address book.
Installing the Web Server (IIS) and the "Active Directory Certificate Service"
Install the required service in the Windows server to obtain user information registered in Active Directory automatically.

Creating a Server Certificate
To encrypt user information, create a server certificate in the Windows server. Windows Server 2016 is used as an example.
On the [Start] menu, click [All Applications], and then click [Internet Information Service (IIS) Manager] of [Administrative Tools].
In the left column, click [Server Name], and then double-click [Server Certificate].
