Organisational unit authority/authorizer?

Also known as an "authorizer" or "access authority", an organisational unit authority is a staff member associated with an organisational unit (usually the line manager) who can authorise or sponsor a third party’s access to UCT facilities. Organisational unit authorities use the Third Party System to review and, either approve or deny, requests from staff members in their org unit who request access for new and/or existing third parties.
