Sorry, I perhaps mis-took the combination of "not officially supported" and "try the forums"
The quote from the salesperson (Russ) is this:
"If zmlicense shows it as enabled then you are good to go."
And indeed, zmlicense -p shows MobileSyncEnabled=true
The error in the log is FF2.0 (Linux)/4.5.6_GA_1044.RHEL5;] sync - HTTP/1.1 403 Account not enabled for ZimbraSync
This sure seems like a bug in the Zimbra Admin interface if I had to guess. I will send a copy of your suggestion to sales and see what I get.
Thanks,
Mark
