Eventually, this new mechanism might replace the ncalrpc_as_system mechanism: I think with this we're much more flexible and even more secure: We rely on the direct permissions on "np/" and don't have to pretend that the local client came from a file on /root. We are more flexible because with this mechanism we can easily fake arbitrary tokens and play with session keys. However, this would require that the source4 librpc code needs to learn about this mechanism, which I was not able to complete. The source3 rpc_server side of this will go away soon, so for now only allow NCACN_NP there. The check in source4 will stay with us for a while, so allow NCACN_NP and NCALRPC to be set remotely here. With NCACN_NP (the case for a client to connect on a named pipe), protect against accidentially connecting as system.

MAILING LIST ETIQUETTE
A few tips when submitting to this or any mailing list.
-
Make your subject short and descriptive. Avoid the words "help" or "Samba" in the subject. The readers of this list already know that a) you need help, and b) you are writing about samba (of course, you may need to distinguish between Samba PDC and other file sharing software). Avoid phrases such as "what is" and "how do i". Some good subject lines might look like "Slow response with Excel files" or "Migrating from Samba PDC to NT PDC".
-
If you include the original message in your reply, trim it so that only the relevant lines, enough to establish context, are included. Chances are (since this is a mailing list) we've already read the original message.
-
Trim irrelevant headers from the original message in your reply. All we need to see is a) From, b) Date, and c) Subject. We don't even really need the Subject, if you haven't changed it. Better yet is to just preface the original message with "On [date] [someone] wrote:".
-
Please don't reply to or argue about spam, spam filters or viruses on any Samba lists. We do have a spam filtering system that is working quite well thank you very much but occasionally unwanted messages slip through. Deal with it.
-
Never say "Me too." It doesn't help anyone solve the problem. Instead, if you ARE having the same problem, give more information. Have you seen something that the other writer hasn't mentioned, which may be helpful?
-
If you ask about a problem, then come up with the solution on your own or through another source, by all means post it. Someone else may have the same problem and is waiting for an answer, but never hears of it.
-
Give as much relevant information as possible such as Samba release number, OS, kernel version, etc...
-
RTFM. Google.
