r20455: Apply some of the patches from Martin Kuehl <kuehl@univention.de> to
better handle the Samba3 backend. I've refactored the password format patch to use the routines in lib/samba3/smbpasswd.c, which has required me to move this into a seperate subsystem, due to recursive dependencies. Andrew Bartlett (This used to be commit 14e2c877a82d1fcf060455f9b46de5767b71438d)
