I know ldap is not an easy area. I have some experiences in setting up 
samba3 with an LDAP. But it is an relative difficult task to set it up 
and to debug it. You need much knowledge of ldap and samba to set it up. 
I think this could be much easier.
I am willing to put much effort in learning more about ldap and samba. I 
think ldap is the best way to manage users.

It sounds much like ldap replication trough samba. Especially the first 
one. The second says nothing to me. Should replication be done with 
samba? I thought this is part of the ldap-server. Why doing it in samba too?
I thought more about the general integration of ldap. I'm not much 
interested in replication. As I said above in my opinion support of ldap 
is way to complicated in samba3. I don't know how this is with samba4. 
But I think there is much to do to make it work out of the box for all 

My problem is that the deadline for application is on March 31th. I 
really want to put much work in it. Even before coding will start. But a 
the moment I've no idea what have to be done in the current development 
tree. I have not much time until end of next week. Otherwise I would 
have an look at the source to get the current state.
