설명

GetUsersInRole 메서드는 ASP.NET 애플리케이션의 구성 파일(Web.config)에 지정된 authorization-manager 정책 저장소에서 지정된 역할과 연결된 사용자 목록을 검색하기 위해 Roles 클래스에서 호출됩니다.

이 메서드는 GetUsersInRole 매개 변수로 지정된 roleName authorization-manager 역할에 직접 포함된 사용자 이름만 반환합니다. 메서드에서 GetUsersInRole 호출하는 기본 authorization-manager API는 그룹 확장을 지원하지 않으므로 중첩된 NT 그룹, 중첩된 authorization-manager 그룹 및 LDAP 쿼리 그룹에 포함된 사용자는 반환되지 않습니다.
