[PATCH] Unique IP address feature for client connections

[Julien Kerihuel]

Hi Lists,

The attached patch (initially proposed by Brad Hards) adds a
localaddress ncacn option to DCERPC binding string and allow clients to
specify on which interface they have to bind to communicate with remote
host.

I have reworked the patch so localaddress becomes a member of the
ncacn_options array and have its own defined flag (1<<22). The patch
also alters EPM connections to use the correct interface.

Typical usage:
ncacn_ip_tcp:192.168.102.236[print,seal,localaddress=192.168.0.142]

Given that we have a local interface with IP 192.168.0.142 and another
one using 192.168.0.140, EPM and DCERPC connections will go through
192.168.0.142.

Also attached the openchange patch (for openchange developers) to test
it prior to any trunk merge. To test the openchange patch, apply it to
trunk, edit the OpenChange profile database and add the localaddress
attribute followed by a local interface IP address, similarly to:

localaddress: 192.168.0.142

If no localaddress parameter is defined, then Samba4 DCERPC stack
fallback to the default behavior (guess the best interface).

Cheers,
Julien.
