I currently have a production environment running Release 7.2.1_GA_2790.UBUNTU10_64 UBUNTU10_64 FOSS edition, configured following this guide: UNIX and Windows Accounts in Zimbra LDAP and Zimbra Admin UI - Zimbra :: Wiki
I have seen some posts regarding the zimbra_posixaccount & zimbra_samba extensions being removed as of 7.2, but they can still be installed (some discussion here: Zimbra 7.2 and posixaccount + samba).
This works great.
However, I set up a test environment for Zimbra 8 and I couldn't use either extension in the GUI. I have to say, using Zimbra to integrate with a Samba PDC is a pretty cool set-up, and I think there are many that would like to be able to do this in the future.
Since official support for these extensions seems to have been dropped, is there anyone in the community that plans to maintain/is maintaining them? Any info would be appreciated. Thanks!
