LDAP Server Fields
The following table describes the unique fields for configuring LDAP servers, for use with the Adding
a Server to a Group” section on page 14-10.
Field Description
Enable LDAP over SSL
check box
When checked, SSL secures communications between the security
appliance and the LDAP server. Also called secure LDAP (LDAP-S).
Note If you do not configure SASL protocol, we strongly
recommend that you secure LDAP communications with SSL.
Server Port TCP port number 389, the port which the security appliance uses to
access the LDAP server for simple (non-secure) authentication or TCP
port 636 for secure authentication (LDAP-S).
All LDAP servers support authentication and authorization. Only
Microsoft AD and Sun LDAP servers additionally provide VPN
remote access password management capability, which requires
LDAP-S.
Server type A drop-down list for choosing one of the following LDAP server
types:
Detect Automatically/Use Generic Type
Microsoft
N ovell
OpenLDAP
Sun
Base DN The Base Distinguished Name (DN), or location in the LDAP
hierarchy where the server should begin searching when it receives an
LDAP request. For example, OU=people, dc=cisco, dc=com.
Scope The extent of the search the server should make in the LDAP hierarchy
when it receives an authorization request. The available options are:
One Level: Searches only one level beneath the Base DN. This
option is quicker.
All Levels: Searches al l levels beneath the Base DN; in other
words, search the entire subtree hierarchy. This option takes more
time.
Naming Attribute(s) The Relative Distinguished Name attribute (or attributes) that
uniquely identifies an entry on the LDAP server. Common naming
attributes are Common Name (CN), sAMAccountName,
userPrincipalName, and User ID (uid).
