Rowland,

The purpose of the 'domain master' parameter is as David describes, to
configure exactly this mode.  

It is not in conflict with 'server role = standalone server', the
parameters are intended to allow this, which is why the default for
'domain master' is 'auto'.

I hope this clarifies things,
