first server in the list, and it attempts to connect to each subsequent server in the order they are listed. 
To ensure that the Cisco appliance connects to your primary LDAP server by default, ensure that you 
enter it as the first server in your list of LDAP servers. 

If the Cisco appliance connects to a second or subsequent LDAP server, it remains connected to that 
server until it reaches a timeout period. After it reaches the timeout, it attempts to reconnect to the first 
server in the list. 

To configure the Cisco appliance for LDAP failover, complete the following steps in the GUI:

From System Administration > LDAP, select the LDAP server profile you want to edit.

From the LDAP server profile, configure the following settings:

Configure other LDAP settings and commit the changes.

To distribute LDAP connections among a group of LDAP servers, you can configure your LDAP profile 
for load balancing.

When you configure your LDAP profile for load balancing, the Cisco appliance distributes connections 
among the LDAP servers listed. If a connection fails or times out, the Cisco appliance determines which 
LDAP servers are available and reconnects to available servers. The Cisco appliance determines the 
number of simultaneous connections to establish based on the maximum number of connections you 
configure. 

If one of the listed LDAP servers does not respond, the Cisco appliance distributes the connection load 
among the remaining LDAP servers.
