I want both of samba and httpd can access it. If I change the type of this directory to "samba_share_t", httpd won't access it. At this time I have to switch the type of this directory frequently. As I know, RBAC can let more than one "Subject" to access the same "Object". So, can a folder or file(Object) can have more than one type?
