option in the NetDefendOS LDAP server setup which has special consideration with Active
Directory and that is the Name Attribute. This should be set to SAMAccountName.
Defining an LDAP Server
One or more named LDAP server objects can be defined in NetDefendOS. These objects tell
NetDefendOS which LDAP servers are available and how to access them.
Defining an LDAP server to NetDefendOS is sometimes not straightforward because some LDAP
server software may not follow the LDAP specifications exactly. It is also possible that an LDAP
administrator has modified the server LDAP schema so that an LDAP attribute has been renamed.
LDAP Attributes
To fully understand LDAP setup, it is important to note some setup values are attributes. These are:
• The Name attribute.
• The Membership attribute.
• The Password attribute.
An LDAP attribute is a tuple (a pair of data values) consisting of an attribute name (in this manual
we will call this the attribute ID to avoid confusion) and an attribute value. An example might be be
a tuple for a username attribute that has an ID of username and a value of Smith.
These attributes can be used in different ways and their meaning to the LDAP server is usually
defined by the server's database schema. The database schema can usually be changed by the server
administrator to alter the attributes.
General Settings
The following general parameters are used for configuration of each server:
• Name
The name given to the server object for reference purposes in NetDefendOS. For example,
NetDefendOS authentication rules may be defined which reference this name.
This value has nothing to do with the Name Attribute described below. It is only for use by
NetDefendOS and not the LDAP server.
• IP Address
The IP address of the LDAP server.
• Port
The port number on the LDAP server which will receive the client request which is sent using
TCP/IP.
This port is by default 389.
• Timeout
This is the timeout length for LDAP server user authentication attempts in seconds. If no
response to a request is received from the server after this time then the server will be considered
to be unreachable.
The default timeout setting is 5 seconds.
