LDAP servers

Lightweight Directory Access Protocol (LDAP) is an Internet protocol used to maintain authentication data that may include departments, people, groups of people, passwords, email addresses, and printers. LDAP consists of a data-representation scheme, a set of defined operations, and a request/response network.

If you have configured LDAP support and an administrator is required to authenticate using an LDAP server, the FortiManager unit sends the administrator’s credentials to the LDAP server for authentication. If the LDAP server can authenticate the administrator, they are successfully authenticated with the FortiManager unit. If the LDAP server cannot authenticate the administrator, the FortiManager unit refuses the connection.

When configuring an LDAP connection to an Active Directory server, an administrator must provide Active Directory user credentials. To secure this connection, use LDAPS on both the Active Directory server and FortiManager. Apply the principle of least privilege. For the LDAP regular bind operation, do not use credentials that provide full administrative access to the Windows server when using credentials.

To use an LDAP server to authenticate administrators, you must configure the server before configuring the administrator accounts that will use it.

To add an LDAP server:

1. Go to System Settings > Remote Authentication Server.
2. Select Create New > LDAP Server from the toolbar. The New LDAP Server pane opens.

   

3. Configure the following settings, and then click OK to add the LDAP server.

   Name		Enter a name to identify the LDAP server.
   Server Name/IP		Enter the IP address or fully qualified domain name of the LDAP server.
   Port		Enter the port for LDAP traffic. The default port is 389.
   Common Name Identifier		The common name identifier for the LDAP server. Most LDAP servers use cn. However, some servers use other common name identifiers such as UID.
   Distinguished Name		The distinguished name is used to look up entries on the LDAP server. The distinguished name reflects the hierarchy of LDAP database object classes above the common name identifier. Clicking the query distinguished name icon will query the LDAP server for the name and open the LDAP Distinguished Name Query window to display the results.
   Bind Type		Select the type of binding for LDAP authentication: Simple, Anonymous, or Regular.
   	User DN	When the Bind Type is set to Regular, enter the user DN.
   	Password	When the Bind Type is set to Regular, enter the password.
   Secure Connection		Select to use a secure LDAP server connection for authentication.
   	Protocol	When Secure Connection is enabled, select either LDAPS or STARTTLS.
   	Certificate	When Secure Connection is enabled, select the certificate from the dropdown list.
   Administrative Domain		Choose the ADOMs that this server will be linked to for reporting: All ADOMs (default), or Specify for specific ADOMs.
   Advanced Options
   	adom-attr	Specify an attribute for the ADOM.
   	attributes	Specify the attributes such as member, uniquemember, or memberuid.
   	connect-timeout	Specify the connection timeout in millisecond.
   	filter	Specify the filter in the format (objectclass=*)
   	group	Specify the name of the LDAP group.
   	memberof-attr	Specify the value for this attribute. This value must match the attribute of the group in LDAP Server. All users part of the LDAP group with the attribute matching the memberof-attr will inherit the administrative permissions specified for this group.
   	profile-attr	Specify the attribute for this profile.
   	secondary-server	Specify a secondary server.
   	tertiary-server	Specify a tertiary server.
