[vlendec at samba.org]

Author: vlendec

New Revision: 17977

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=17977

Log:
To be honest, I have NO idea whatsoever what this does, but it fixes what I
have been able to reproduce with smbtorture4 for bug number 4059. It's too
late here now to check with W2k native, I'll do that tomorrow or over the
weekend. I'll then also check in a samba4 torture test to walk this from now
on.

Abartlet, can you do me a favor and look over this? It is a 1:1 copy of the
corresponding Samba4 code.

Thanks,

Volker
