Updating Mobile Briefcase Domain
From unroole CMS wiki
For more information, see Mobile Briefcase Domain.
Both the name and description of a mobile domain can be updated. When updated each user who belongs to that domain is also updated to reflect the change in domain name so the relationship is not lost.
It's worth noting however than when a domain name is changed all of the users currently logged into the mobile briefcase application with the old domain will need to re-login to update their data.
