Comment 13 for bug 1271426

admin role needs to be added to read permission to be able to update it. (In the case where your user does not have the _member_ role, only admin)

New example:

[^provider_.*$]
create = admin
read = admin,_member_
update = admin
delete = admin

# Note the trailing $ to make sure all the string is matched
[^((?!provider_).)*$]
create = _member_
read = _member_
update = _member_
delete = _member_
