Cisco Cisco Email Security Appliance C160 Mode D'Emploi

When you configure an LDAP profile, you can configure the IronPort appliance 
to connect to a list of multiple LDAP servers. To use multiple LDAP servers, you 
must configure LDAP servers to contain the same information, use the same 
structure, and use the same authentication information. (third party products exist 
that can consolidate the records).

When you configure the IronPort appliance to connect to redundant LDAP 
servers, you can configure the LDAP configuration for failover or load balancing. 

You can use multiple LDAP servers to achieve the following results:

Failover. When you configure the LDAP profile for failover, the IronPort 
appliance fails over to the next LDAP server in the list if it cannot connect to 
the first LDAP server.

Load Balancing. When you configure the LDAP profile for load balancing, 
the IronPort appliance distributes connections across the list of LDAP servers 
when it performs LDAP queries.

You can configure redundant LDAP servers from the System Administration > 
LDAP page or from the CLI 

ldapconfig

 command.

Use the Test Server(s) button on the Add (or Edit) LDAP Server Profile page (or 
the 

test

 subcommand in the CLI) to test the connection to an LDAP server. If you 

use multiple LDAP servers, AsyncOS tests each server and displays individual 
results for each server. AsyncOS will also test the query on each LDAP server and 
display the individual results.
