The redundant-load-balance Statement

The redundant-load-balance section operates as a combination of the redundant and load-balance sections. When the section is entered, one module is chosen at random to process the request. If that module succeeds, then the server stops processing the section. If, however, the module fails, then the next module in the list is chosen (wrapping around to the top). This process continues until either one module succeeds or all of the modules have failed.

All of the modules in the list should be the same type (e.g., ldap or sql). All of the modules in the list should behave identically, otherwise different requests will be processed through different modules and will give different results.
