Makefile.in :
- added srvsvc client files
clientgen.c :
- replaced cli_error(cli, int *cls, int *err) with
cli_error(cli, uint8 cls, uint32 *err). this version detects
32 bit status messages. the DOS error "MORE_DATA", the
equivalent of the 32 bit *warning* 0x8000 0005
(STATUS_BUFFER_OVERFLOW), was being processed as an error,
terminating the cli_receive_trans() call.
cli_pipe.c :
- replaced calls that had been incorrectly modified from
32 bit warnings (0x8000 0005 - STATUS_BUFFER_OVERFLOW)
to 8 bit DOS errors (0x01 0xEA - MORE_DATA).
the use of the old version of cli_error (DOS only)
instead of the new one (DOS and 32 bit) caused the
dce/rpc client code to fail.
- replaced 2 space indentation with tab indentation in all functions.
cli_srvsvc.c :
cmd_srvsvc.c :
- added these files back in, fixing them up to use jeremy's
modified versions of the dce/rpc client functions.
parse_srv.c :
- added back in some "unused" functions required by dce/rpc
client-side code. it would be helpful if all such "unused"
functions could be added back in.
rpcclient.c :
- added "session", "file", "share", "connection" enumeration
functions back in. these are equivalent to nt's "NetXXXXXEnum"
Win32 (MSDN) functions.
- added "srvinfo" function back in. this is equivalent to
nt's NetServerGetInfo Win32 (MSDN) function.

Jeremy requested that I get my NTLMSSP patch into CVS. He didn't request
the schannel code, but I've included that anyway. :-)
This patch revives the client-side NTLMSSP support for RPC named pipes
in Samba, and cleans up the client and server schannel code. The use of the
new code is enabled by the 'sign', 'seal' and 'schannel' commands in
rpcclient.
The aim was to prove that our separate NTLMSSP client library actually
implements NTLMSSP signing and sealing as per Microsoft's NTLMv1 implementation,
in the hope that knowing this will assist us in correctly implementing
NTLMSSP signing for SMB packets. (Still not yet functional)
This patch replaces the NTLMSSP implementation in rpc_client/cli_pipe.c with
calls to libsmb/ntlmssp.c. In the process, we have gained the ability to
use the more secure NT password, and the ability to sign-only, instead of
having to seal the pipe connection. (Previously we were limited to sealing,
and could only use the LM-password derived key).
Our new client-side NTLMSSP code also needed alteration to cope with our
comparatively simple server-side implementation. A future step is to replace
it with calls to the same NTLMSSP library.
Also included in this patch is the schannel 'sign only' patch I submitted to
the team earlier. While not enabled (and not functional, at this stage) the
work in this patch makes the code paths *much* easier to follow. I have also
included similar hooks in rpccleint to allow the use of schannel on *any* pipe.
rpcclient now defaults to not using schannel (or any other extra per-pipe
authenticiation) for any connection. The 'schannel' command enables schannel
for all pipes until disabled.
This code is also much more secure than the previous code, as changes to our
cli_pipe routines ensure that the authentication footer cannot be removed
by an attacker, and more error states are correctly handled.
(The same needs to be done to our server)

work in this patch makes the code paths *much* easier to follow. I have also
included similar hooks in rpccleint to allow the use of schannel on *any* pipe.
rpcclient now defaults to not using schannel (or any other extra per-pipe
authenticiation) for any connection. The 'schannel' command enables schannel
for all pipes until disabled.
This code is also much more secure than the previous code, as changes to our
cli_pipe routines ensure that the authentication footer cannot be removed
by an attacker, and more error states are correctly handled.
(The same needs to be done to our server)
