  I know these systems work with AD, the problem is the migration, I  
don't think is easy to migrate 5000 accounts from current systems to  
new systems. I will need to learn the sintaxes of all these new  
systems and this would take huge time because I know nothing of  
samba4, or AD, or dovecot, or kerberos and the boss whants the emails  
for students for next month. We don't plan to change cyrus/postfix and  
horde, whats the problem with them? I already tried kopano and the  
users hated it. And like I said there are a lot of internal  
administrative systems that were programmed (not by me) to work with  
ldap only, including some that are not opensource. A while ago I did  
research on how to migrate my current domain to samba4 and from what I  
understand it would be almost impossible or too difficult for my
