We are in the process of setting up customer community. We have a custom object with read/write access to customer community users. This custom object has a lookup to Account. Sharing settings for this custom object is set to Private and through sharing rules we have given R/W access to Internal users.
When the customer community user creates a new custom object record, for Account lookup, they should be able to select only their Account (for which their contact record is setup with). In the communities, we used the sharing set on Account (User:Account = Account:Id), but even then the community user cannot see any Account records on the lookup of the custom object record.
Can anyone provide directions on how do we share Account records to customer community users. ( they should be able to see only their Account)
