LDAP
If your network includes LDAP, configure the LDAP Sign In Setup and the LDAP Users
and Groups options (Figure 5).
Figure 5: The LDAP Sign In Setup options.
Figure 6: The LDAP Users and Groups options.
These settings enable the MFPs to require a user's logon credentials for use of the MFPs. This is
related to the LDAP access options in the Digital Sending category, which enable the MFP to use
the LDAP address book.
Note:
Uploading a certificate for use with SSL can be done under the Device
Certificates Option in the Device category. This applies to any
certificates including those created by the Certificate Authority server on
your network.
