/* This is a copy of the definition in the samba gen_ndr/security.h header

* string or binary representation since those are not made available by
* public samba libraries.
*
* If the definition ever changes on the samba side we have to adopt the
* change. But chances are very low that this will ever happen since e.g. this
* struct is also defined in public documentation from Microsoft. See e.g.
* section 2.4.2.3 of "[MS-DTYP]: Windows Data Types"
* http://msdn.microsoft.com/en-us/library/cc230364(v=prot.10)
