[Pgbuildfarm-members] ldap config option

There is a new configuration option that you should consider for your
buildfarm member(s). The option is to enable the service config to be
found via LDAP, and is simply --with-ldap. Adding the code below near
the bottom of your config file should be sufficient to activate it if
your libraries etc. are in standard locations.

if ($branch eq 'HEAD' || $branch ge 'REL8_2')
{
push(@{$conf{config_opts}},"--with-ldap");
}

cheers
