Automatic configuration sychronization within a Serv-U cluster

kwanpr

Serv-U allows customers to deploy a HA architecture.  However, the more Serv-U a customer has in the cluster, the more support overhead will be there because configuration will not be synchronized against the Serv-U cluster .  Customer need to replicate the configurations on each Serv-U which increase the support work load and increase the chance of mistake.

In my set up, I leverage LDAP to do the authentication.  I need to create the OU and user group on each Serv-U.  After the set up, I need to cross check each Serv-U instance to make sure I didn't miss the set up on any instances.
