Table 3-12 Authentication bind methods (continued)
Bind method Description Can be used by
Simple The selected LDAP server requires user credentials but does not
support NTLM or SPNEGO.
The password, if any, is sent non-encrypted across the network.
The process requires a username and password.
Windows
Novell
LDAP
Simple over Secure
Channel (SSL)
The selected LDAP server requires user credentials but does not
support NTLM or SPNEGO.
All data, including the username and password, is encrypted by
using the Secure Sockets Layer (SSL).
The LDAP server must be set up to support SSL.
Windows
LDAP
Windows Negotiated
(SPNEGO)
The selected LDAP server requires user credentials and supports
SPNEGO and SSL.
Use this selection negotiate the strongest authentication protocol
that both the LDAP Server and the DSS server support.
Kerberos 5 is supported for Active Directory authentication.
NTLM is supported for Exchange 5.5 server authentication.
Windows
Search root
The search root is the distinguished name (DN) of the entry in the LDAP directory where the search is
to begin. A DN is made up of 'attribute=value' pairs separated by commas.
In Windows Active Directory Services, the search root normally takes the form:
CN=Users,DC=domain_name,DC=domain_suffix. To limit the address search even more, for
example, to a single organizational unit (OU), add components to the search root. For example, to
search for users in the "accounting" OU, add "OU=accounting" to the search root
(OU=accounting,CN=Users,DC=domain_name,DC=domain_suffix). By using these methods
to configure the search root that is used in authentication, access to Digital Sending features can be
limited to a subset of users in an organization. Several methods can be used to determine the search
root.
NOTE: On some LDAP servers, the search root can remain blank. In this case, the root node is
assumed to be the starting place.
How to
Use the Configuration Utility Authentication tab to control how users are authenticated when using
the Digital Sending features.
Authentication consists of two interdependent parts. First, the device verifies the user's credentials by
using the selected authentication method. Then, the device attempts to find the user's e-mail address
in the database of an LDAP server by using settings that are specific to the LDAP server. If either
step fails, the user is denied access to the Digital Sending features. These two steps utilize two
distinct technologies (an authentication server and an LDAP server), except in the case of the LDAP
server method, where both steps are accomplished by using the LDAP server. To enable
