I would like to run a zmprov ma command on all user accounts.

I have already tested that this works:

zmprov ma user@mydomain.com zimbraPrefSharedAddrBookAutoCompleteEnabled TRUE

This sets the "Include addresses in shared address books" in the preferences which unfortunately is not a setting in the Class of Service in the Web Administration Panel.

I would like to run this for all users though. Can I use a "*" to run the command for all users?
zmprov ma * zimbraPrefSharedAddrBookAutoCompleteEnabled TRUE
