Hi!
As I said in my commit message, I hate to pass down boolean flags to
inner functions to trigger something magic. Thus I had the idea to
pass down a function that decides whether to update the LDAP DB. This
way the complete logic is lexically much closer together. C syntax
does not make that nice, but we have to live with that.
What do you think about that (completely untested) patch?
Volker
P.S: If we only had a *real* programming language at hand... Anybody
about to re-write Samba in ML or so? ;-))
