Hi Felipe,

Unfortunately it is not possible using JCIFS. You would have to
construct and write the directory security descriptor. And there are
funky rules about setting permissions on directories that require
walking through all sub-objects and modifying their descriptors.
Suffice it to say this sort of thing is non-trivial. JCIFS can read
and decode security descriptors but it cannot write them. One reason
the code for writing security descriptors was never implemented was
because it is dangerous. You could probably really screw up
permissions on things if you're not careful. Put the mouse down and
step away from the keyboard. Just walk away from this one.

Note that you should never use credentials in the URL. Use the
NtlmPasswordAuthentication class to create credentials and then pass
that to the SmbFile* constructors separately.

Mike
