Bug Description:  When FIPS mode is enabled on the security database, the
                  token name is changed.  This prevents the server from
                  reverse decoding the replication manager's password.  Which
                  prevents replication sessions from getting established.

Fix Description:  Instead of getting the key slot from the harded coded token
                  name, call slapd_pk11_getInternalKeySlot() which gets the
                  current slot.
