I'm running zarafa 6.20.7 and I'm planning to manually migrate a small (2 user) system from the db user plugin to LDAP. It looks like I just need to set the externid fields in the users table in the database to the user's uidNumber from LDAP and then swap over the USER plugin configuration in server.cfg. Can someone confirm that this is correct please?

Do I also need to create a zarafaAccount attribute in LDAP, as suggested by the wiki ()?

Do I also need to create the zarafa-users group in LDAP, or can I use my existing group as the search base?

Needless to say, I will of course backup the database before attempting this. Indeed, I have a backup server with which to experiment before breaking my production server.
