**Guest access:** The guest access permissions (if several selected) applied using OR logic. If any one allows an option then the final result = allow

**Named OPAC user (without role):** We apply Guest access permissions then extend allowed options with Named OPAC permissions and users AP. The Named OPAC permissions (if several specified) combined using AND, i.e. both should allow to enable a setting. Same applied to Users assigned AP and then in the end Named OPAC combine with AP assigned to user also using AND (everything combined using AND except Guest) Final will be union of named opac and user private using AND with adding additional options from Guest.

**Named OPAC user (with role):** Same as above except AP assigned to Named OPAC are not applied (Only guest + AP assigned to user applied)
