[cifs-protocol] repsFromTo blob format (WSPP CAR)

[tridge at samba.org]

We've been unable to find a description in the WSPP docs of the format
for the repsFromToBlob blob that is used to encode the repsFrom and
repsTo attributes in DRS/LDAP.

For now we have produced our own IDL for the blobs, which you can see
here:

  http://samba.org/ftp/unpacked/samba_4_0_test/librpc/idl/drsblobs.idl

in the typedef for the structure repsFromToBlob, but it would be good
if we could confirm this with IDL (or other binary structure encoding)
in the WSPP docs.

The MS-DRSR doc shows some examples for version1 of the structure, but
nothing for version 2 (version 2 is used by W2K8).

Cheers, Tridge
