Hmm - I object.

posixGroup and groupOfURLs are both "structural" objectclasses so an
entry is either a "groupofURL" or a "posixGroup", never both. And in
this case the memberURL can have different meanings according to the
Objectclass it is used in.

Otherwise I'd have to create an Attribute for every expansion I want to
use - that can't be right!

You are right for expansions in auxillary OCs, of course! They shouldn't
be using the same attribute...

Will do, sometime soon.
