Sharing calendars to group with zmmailbox - permission denied

[smcgrath1111]

Here's my situation:

-User A has shared his calendar, with view permission, to a distribution list called "Group"
-User B joins "Group"

-Using zmmailbox to share User A's calendar with User B:

zmmailbox -a admin -p password -m userA@domain.com createMountpoint --view appointment "/User A's Calendar" userB@domain.com /Calendar

ERROR: service.PERM_DENIED (permission denied: you do not have sufficient permissions on folder /Calendar)

Shouldn't user B have permission because he is a member of Group? I think this worked when I was on 4.5.6, but doesn't seem to work on 5.0.1. However, I may be wrong and doing something dumb as well.

So, to follow up, apparently I have a different problem that is causing this, and it has to do with a broken user account.

I won't go into it on here, but I didn't want this thread to end up a wild goose chase. Thanks to all, anyway
