Author: tridge

New Revision: 3608

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=3608

Log:
added BASE-DENYDOS test

this test demonstrates how w2k3 handles the special semantics of
DENY_DOS when 2 opens happen on the same connection. The 2nd open
doesn't actually do a NTFS open, it happens as a secondary reference
to the same internal file handle in the CIFS layer. The evidence is
that the 2nd open shares the same POSITION_INFORMATION field as the
first open, but only for the special DENY_DOS cases that would
normally be refused.
