/* this structure is just a wrapper for a string, the only reason we
   bother with this is that it allows us to check the length provided
   on the wire in testsuite test code to ensure that we are
   terminating names in the same way that win2003 is. The *ONLY* time
   you should ever look at the 'private_length' field in this
   structure is inside compliance test code, in all other cases just
   use the null terminated char* as the definitive definition of the
   string

   also note that this structure is only used in packets where there
   is an explicit length provided on the wire (hence the name). That
   length is placed in 'private_length'. For packets where the length
   is always determined by NULL or packet termination a normal char*
   is used in the structure definition.

   use the same structure for dom_sid2 as dom_sid. A dom_sid2 is really
   just a dom sid, but with the sub_auths represented as a conformant
   array. As with all in-structure conformant arrays, the array length
   is placed before the start of the structure. That's what gives rise
   to the extra num_auths elemenent. We don't want the Samba code to
   have to bother with such esoteric NDR details, so its easier to just
   define it as a dom_sid and use pidl magic to make it all work. It
   just means you need to mark a sid as a "dom_sid2" in the IDL when you
   know it is of the conformant array variety
