I'm an happy admin of a Zimbra server since this summer, now with 142 users (most of them using Outlook Connector), and I'm preparing for the big upgrade from 5.0.18 to 6.0.4. I've looked around the wiki and as far as I can tell the upgrade should be pretty easy, but I have some doubts about the posix accounts stuff.
We use Zimbra's LDAP to authenticate the users on our intranets and servers (ssh and samba), so I've installed the zimlets and changed the ldap schema according to the Wiki for 5.x. I've looked around and sometimes I see that everything should be upgraded smoothly, and some other times it looks like there are some changes to be made before the upgrade.
Can someone tell me what I should expect and do?
Thanks for your help!
