How to use Posix, group name

I am using Zimbra and have the samba and posix extensions enabled. I would like to pre-populate the roster. I understand the only way is to use posix. I am trying to configure the server now, and I am step 3 “Group Mapping” . My question is what do I put where so Openfire can read the groups within Zimbra correctly.

Thanks in advance.
