Newbie here, loaded zentyal community (latest addition) about a week ago and have been struggling to join it to my sbs2011 install as a backup domain controller. Suddenly, tonight as I'm messing with it, again, ready to give up, an update pops up, I figure what the heck, worth a try. Bam! It's working! as soon as the update finished my users and groups populated. logs were all related to login issues. I don't know if I want to kill or kiss someone. I hope this isn't typical of the zentyal experience, I don't think my heart could take it.
