Changing your samba password from windows

[Jim McDonough]

Ok, I've got a question about the code involved in this:  in
rpc_parse/parse_samr.c, in the function samr_io_r_get_dom_pwinfo, the third
"unknown" field has been #ifdef'ed out (it's also been removed from the
structure).  If I put it back in, I can successfully change my password
from Win2k.  Why was it taken out?

Group,

The other place that this little error message pops up is when you input
and
incorrect password when trying to log into a Win2K client.  I'm sure the
two
are related, but the RPC stuff is over my head....

Regards,

Greg
