(This used to be commit 9b5c5bc3f3912776af6a8c9b13a9cb8dd2eff8f8)
workgroup, decided periodically to stop sending recognized responses to a
NetServerEnum2 request for the workgroup. Instead of returning the list of
servers (only itself; nothing else in the workgroup), it returns a status code
of 8 which is unsupported by samba3, samba4, and ethereal.
The code for this request assumed that if an unexpected status code was
received, the connection had a problem, i.e. that cli_errno() would show a
problem. That turns out not to be the case.
This patch changes the behavior so tha any time a response is received and
cli_errno() == 0, we continue processing the reply and base our response on
the returned count (zero). The pre-existing code then converts this count=0
into an ENOENT errno which can be properly handled by the application (whereas
an error return with errno=0 can't be).
This packet dump has only 2 frames. Sorry about the text version but it's
most easily attached to this log message. I also have it saved as .pcap if
anyone wants it.

least with dummy routines. We need a way to indicate that we do not support a
call, so that srv_pipe_hnd.c can return the DCE level RNG_ERROR.
This flag can be set in the backend routines for this one. I'll change pidl to
generate code to "return False" in srv_lsa.c if this flag is set.

That way we ensure winbindd only deals with fully

(This used to be commit 0523ad249335c6094854bc9cefb46e2095f4c0ba)
I have some problems resolving the last 3 ones in attrib_handlers.c. In line
251 the function ldb_dn_explode_casefold is called with mem_ctx as the first
argument. Looking at ldb_dn_explode_casefold I see that the first argument it
expects is a struct ldb_context. I could certainly add a cast to (struct
ldb_context *) to that call, but I would assume that this is the wrong fix. Is
it possible that attrib_handlers.c:251 and :254 should have ldb and not
mem_ctx as the first argument?
Can anybody from Samba4 clarify this for me and apply the correct fix?
Thanks a lot.
