Exchange is heavily dependent on Active Directory. As much as I love Linux, I would NOT recommend this route unless you are willing to give up Exchange as well. Of course, there are many Exchange alternatives such as Zimbra, Kerio Mail, and Scalix. <div class="gmail_quote">On Wed, Jan 7, 2009 at 2:15 PM, Rob Owens <<a href="mailto:rowens@ptd.net">rowens@ptd.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I have an existing Windows 2003 server that's running Active Directory and Exchange. As part of my "baby steps" process, I'd like to replace the AD system with Samba/LDAP but keep the Exchange server for email (for now). Does anybody have experience doing such a thing, and can anybody offer me any advice? I fear that Exchange may complain when AD is turned off... -Rob _______________________________________________ K12OSN mailing list <a href="mailto:K12OSN@redhat.com">K12OSN@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/k12osn" target="_blank">https://www.redhat.com/mailman/listinfo/k12osn</a> For more info see <<a href="http://www.k12os.org" target="_blank">http://www.k12os.org</a>> </blockquote></div> -- Regards, Conrad Lawes
