Once you create the domain-based query, you need to associate it with a public or private 
listener.

Submit and commit your changes.

A chain query is a series of LDAP queries that the appliance attempts to run in succession. The appliance 
attempts to run each query in the “chain” until the LDAP server returns a positive response (or the final 
query in the “chain” returns a negative response or fails). Chain queries can be useful if entries in your 
LDAP directory use different attributes to store similar (or the same) values. For example, you might 
have used the attributes 

maillocaladdress

 and 

mail 

to store user email addresses. To ensure that your 

queries run against both these attributes, you can use chain queries. 

Create server profiles for each of the queries you want to use in the chain queries. For each of the server 
profiles, configure the queries you want to use for a chain query. For more information, see 

.

Create the chain query. For more information, see 

Enable the chain query on the public or private listener. For more information about configuring 
listeners, see the “Configuring the Gateway to Receive Mail” chapter.

You can also enable domain-based queries for LDAP end-user access or spam notifications for the Spam 
Quarantine. For more information, see the Spam Quarantine chapter.

You create a chain query from the System Administration > LDAP > LDAP Server Profiles page. 

From the LDAP Server Profiles page, click Advanced.

Click Add Chain Query.

Add a name for the chain query.

Select the query type. 

When you create chain queries, you cannot select different types of queries. Once you select a query 
type, the appliance populates the query field with queries of that type from available server profiles.

Select a query to add to the chain query.
