I've implemented Account/Contact security via Entity Permissions on our Dynamics 365 Portal, and though it works, now I find that Accounts want the ability to share specific, individual records with other Accounts.
I know it's trivial to Assign/Share Records within CRM itself, but does anyone have any ideas on how to implement similar functionality for a Dynamics 365 Portal application with custom entities? I'm hoping not to resort to plugins. I have a few ideas on how to do this, but I'd really like to get other opinions.
Any ideas?
