If you have multiple LDAP servers for access to your user source (directory), you can configure your ZENworks Servers to recognize each of the LDAP servers. This provides both load balancing and fault tolerance.
For example, if you have multiple ZENworks servers, you can configure each one to access the user source through a different LDAP server. This distributes the workload more evenly among the LDAP servers.
Likewise, for each ZENworks server, you can list multiple LDAP servers through which it can connect to the user source. If one of the LDAP servers becomes unavailable, the ZENworks Server uses another LDAP server.
