When configuring LDAP authentication for a TeamForge instance, there may be a business need for using multiple LDAP servers. Follow the guidelines below for configuring.
The additional LDAP servers can be added to the java.naming.provider.url option in login-config.xml:
login-config.xml:
<module-option name="java.naming.provider.url">
ldap://primary/ ldap://secondary/</module-option>
Once the primary and secondary servers have been defined, they will be consulted in order of definition for every authentication request. First the primary, and if the primary fails, then the secondary. This prevents specifying multiple servers for round-robin handling of authentication, but it can still be used for redundancy needs.
