Subject: [PATCH 42/44] Ticket 47379 - DNA plugin failed to fetch replication
 agreement

Bug Description:  When trying to get the next range of available values, if a shared config
                  server does not have a replication agreement that points to itself then
                  it can not obtain the bind credentials/info to successfully contact that
                  server when trying to get the next range.

Fix Description:  Extend the shared config server to allow for bind information, such as bind
                  method, and connection protocol.  For the bind DN and pw(for SIMPLE and DIGEST-MD5
                  bind methods), we store this in the plugin config entry.  As each bind pw needs to
                  use DES pw storage scheme, and this must be local to each server (not replicated
                  with the shared config server entry).

                  Fixed infinite loop in dna_fix_maxval() - we did not advance the server list if
                  there was a error.  Also improved config validation to make sure the shared config
                  entry is not within the scope & filter of the DNA config.
