Sync Contacts

[bizza]

Hi,
i'm working in a test environment with zimbra 7.1.0, bes express 5.0.2 and zcb 7.1.
Due to a zcb/bexs limitation i can't push shared address book to devices
(Bug 43108 – The ability to sync shared contact lists. and Bug 30986 – Add a connector for a shared/global contact list on all Blackberry's), and i need to find a workaround.

My idea is to create an user with shared address book, and sync it with user personal address book putting on each contact a tag (for example "Corporate Contact").

I've read zmmailbox documentation but i can't found anything.
Any idea?

regards
Marco
