Add High Availability for LDAP¶

Warning

This guide helps you to configure client-side load balancing. While we don't recommend client-side load balancing, we strongly recommend setting up high availability on the LDAP server side through server-side load balancing.

When connecting the WSO2 Identity Server to an LDAP user store, it may be necessary to have high availability for the LDAP as it includes user information that must be available at all times. To attain high availability for your LDAP, you would replicate the LDAP server to effectively handle failover.

This topic provides instructions on how to configure WSO2 Identity Server when you add high availability to your LDAP.

Open the <IS_HOME>/repository/conf/deployment.toml file and find the userstore manager config relevant to your LDAP.
```
[user_store]
type = "read_write_ldap_unique_id"
...
```
Failover for LDAP is configured by defining LDAP connection URLs. Add connection_url to the deployment.toml file. Following is an example of how this can be configured.
```
[user_store]
type = "read_write_ldap_unique_id"
connection_url = "ldap://localhost:10500 ldap://localhost:10511"
...
```
Note

This can be done for either a primary or secondary LDAP userstore with failover configuration. In this example, if you cannot connect to ldap://localhost:10500, you automatically connect to ldap://localhost:10511.
