Ticket 49454 - SSL Client Authentication breaks in FIPS mode
    
    Bug Description:  Replication using SSL Client Auth breaks when FIPS
                      is enabled.  This is because FIPS mode changes the
                      internal certificate token name.
    
    Fix Description:  If FIPS is enabled grab the token name from the internal
                      slot instead of using the default hardcoded internal
                      token name.
