Implementing LDAP/LDAPS Remote Authentication
Lightweight Directory Access Protocol (LDAP/LDAPS) is a networking
protocol for querying and modifying directory services running over
TCP/IP. A client starts an LDAP session by connecting to an
LDAP/LDAPS server (the default TCP port is 389). The client then sends
operation requests to the server, and the server sends responses in turn.
Reminder: Microsoft Active Directory functions natively as an
LDAP/LDAPS authentication server.
To use the LDAP authentication protocol, enter the following
information:
1.
Click User Management > Authentication Settings to open the
Authentication Settings page.
2. Select the LDAP radio button to enable the LDAP section of the
page.
3. Click the
icon to expand the LDAP section of the page.
4. In the Primary LDAP Server field, type the IP address or DNS name
of your LDAP/LDAPS remote authentication server (up to 37
characters). When the Enable Secure LDAP option is selected, the
DNS name must be used.
5. In the Secondary LDAP Server field, type the IP address or DNS
name of your backup LDAP/LDAPS server (up to 37 characters).
When the Enable Secure LDAP option is selected, the DNS name
must be used. Note that the remaining fields share the same settings
with the Primary LDAP Server field. Optional
6. In the Secret Phrase field and again in the Confirm Secret Phrase
field, type the server secret (password) required to authenticate
against your remote authentication server (up to 45 characters).
Enter the password in use on the LDAP/LDAPS server.
7. In the Dialback Query String field, type the dialback query string. If
you are using Microsoft Active Directory, you must enter the
following string: msRADIUSCallbackNumber
Note: This string is case sensitive.
8. Select the Enable Secure LDAP checkbox if you would like to use
SSL. This will enable the Secure LDAP Port field. Secure Sockets
Layer (SSL) is a cryptographic protocol that allows Dominion KX II to
communicate securely with the LDAP/LDAPS server.
9. The default Port is 389. Either use the standard LDAP TCP port or
specify another port.
