If [LDAP to Local] or [Local to LDAP] is selected, the operation becomes as
follows.
If a password error occurred at the first authentication destination, the
authentication process moves to the next destination.
If an authentication error occurred at the first and next authentication
destinations, a notification of the details of the error that occurred in the first
destination is sent.
3. For [Auto Login], select whether or not to enable automatic login.
The automatic login setting is applied immediately after an administrator
logout. To change the settings while the [Auto Login] is [ON], perform
administrator login from the [Maintenance Menu] window or perform the login
via the Admin Tool.
If Central Admin is enabled in a scanner for which automatic login is enabled,
when the scanner is started or resumed from standby mode, preference is
given to checking for available scanner settings, add-in installs and system
settings in the Central Admin Server, over automatic login.
When scanner settings, Add-ins or system settings are available, they are
installed in the scanner. If the number of scanners connecting to the Central
Admin Server exceeds the maximum number possible, the installation is
skipped, and automatic login is performed.
Updates will be applied to the scanner when a logout is performed from the
[Administrator Login] window, when the scanner starts next time, or when the
scanner resumes from standby mode.
4. When [Auto Login] is set to [On], enter a [User Name] and [Password].
The scanner follows the Active Directory user name format when authenticating the
user login.
