Authassignment Table With 2 User Tables

Hi,

I have 2 DB tables for 2 very different set of users. I have just started to implement RBAC for these users.

Looking at the authassignment table it has the following tables:




- itemname

- userid

- bizrule

- data



When user 1 from my sellers_table gets assigned, there record will be:




- seller

- 1

- NULL

- N;



When user 1 from my buyers_table gets assigned, there record will be:




- buyer

- 1

- NULL

- N;



Could this be an issue when checking access. I.e - a seller could have access to a buyer action and visa versa purely because they have the same userid in the authassignment table??

???
