I'm trying to replicate as far as I can a copy of the old windows NT domain and exchange server environment for a lot cheaper in Linux
I know I can use LDAP for a centrally managed address book. What can I use for a central managed but user editable calender for the enterprise?
In NT if a user changed his password it would change for all servers (the domain logon) and other things like his mailbox password. What can I use in Linux to replicate this functionality?
Pros and Cons for each system please? Any Ideas?
