Tech Tip: High-availability LDAP

Using Stingray Traffic Manager to load balance a pool of LDAP servers for High Availability is a fairly simple process.  Here are the steps:

  1. Start up the Manage a new service wizard.  This is located in the top right corner of the Stingray Traffic Manager web interface, under the Wizards drop down.
  2. In step 2 of the wizard set the Protocol to LDAP.  The Port will automatically be set to 389, the default LDAP port.  Give the service a Name.
  3. In step 3 add in the hostnames or IP Addresses of each of your LDAP servers.

At this point a virtual server and pool will be created.  Before it is usable a few additional changes may be made:

  1. Change the Load Balancing algorithm of the pool to Least Connections
  2. Create a new Session Persistence class of type IP-based persistence (Catalogs -> Persistence) and assign it to the Pool
  3. Create a Traffic IP Group (Services -> Traffic IP Groups) and assign it to the virtual server.  The Traffic IP Group is the IP Address LDAP clients will connect to.

The final step is to install the LDAP Health Monitor.  The LDAP Health Monitor is an External Program Monitor that binds to the LDAP server, submits an LDAP query, and checks for a response.  Instructions to install the monitor are in the linked page.
