Using %u in an include parameter

this needs to be considered very carefully.  it's feasible, however all
these extensions being considered are going to stress the smb.conf concept
quite a lot, and it's already a complex issue to be able to get msrpc
daemons to have the same chracteristics as the smbd process that requested
the services of an msrpc daemon. On Thu, 3 Feb 2000, Richard Sharpe wrote:

what happens to rpcclient, smbclient and nmbd etc, which do not _have_ the
concept of a %u?

what behaviour is expected?

should the standard_sub() just be ignored?

where are you going to _get_ a connection_struct from in order to be able
to call handle_include, in rpcclient, smbclient and nmbd?

in fact, in anythoing _other_ than smbd, you can't.

%u and all other associated parameters in standard_sub only actual mean
anything to smbd, and no other programs.

this implies that another "include" parameter is actually needed, on a
per-share basis:


share include = /usr/local/samba/lib/smb.conf.%u

then and only then will %u actually have significcance, as it's really
clear that it's a per-share thing.

comments anyone?  am i off-the-beaten-track, here?  anyone see any logic
flaws here?
