As of version 26.03 of Carbonio CE, the zmfixperms utility is gone!
I can’t even count how many times this amazing little command saved my life during all sorts of support sessions for both Zimbra and Carbonio. So, for posterity’s sake, I decided to make a copy, rename it to something more convenient, and share it here with you.
It’s now called cbfixperms. Just download it, copy it to the Carbonio path, and run it as usual.
Of course, Zextras must have their reasons, and it’s possible that running a command to force-fix permissions could cause issues in the future. Use it only as a last resort.
Heads up! I take no responsibility for the performance or results of this command. Use it at your own risk.
