Jeremy Allison ffab54750f chgpasswd.c: Changed back to getsmb... from getsam... 
ldap.c: Stoped dummy_function being prototyped.
loadparm.c: Fixed slprintf sizes.
nisppass.c: Fixed safe_strcpy sizes.
nmbd_processlogon.c: Changed back to getsmb... from getsam...
nttrans.c: Just a dump of new code.
passdb.c: Moved stuff around a lot - stopped any lookups by rid. This
          needs to be indirected through a function table (soon).
password.c: Changed back to getsmb... from getsam...
reply.c: Changed back to getsmb... from getsam...
slprintf.c: Fixed prototype problems.
smb.h: Fixed prototype problems.
smbpass.c: Changed to getsmbfile....
smbpasswd.c: Changed back to getsmb... from getsam...
lib/rpc/server/srv_netlog.c: Changed back to getsmb... from getsam...
lib/rpc/server/srv_samr.c: Fixed rid lookup - use uid or gid lookup.
lib/rpc/server/srv_util.c: Changed back to getsmb... from getsam...
Jeremy.
