Hey Guys,

I am trying to convince my co-workers to move from Exchange 2003 to a unix implementation of sendmai/dovecot.  They have a couple of concerns that I am sure can be resolved.  First, is there a way for dovecot running on a linux server to authenticate a user to a windows 2003 domain controller?  If so, then where can I get information on how to implement and test this feature?  Also, do you guys know of any calender software that can be used with this implementation as well?  Where users can maybe share their meetings?  Any comments or suggestions would be grately appreciated.

Thanks in advance,
-Jagga
