/* database the correct ACL: i.e., one whose manager type UUID is */
/* identical to the manager_type parameter we were passed: this is */
/* the manager whose ACL the runtime is trying to bind to. The */
/* point is that the ACL library is going to call all its regis- */
/* tered resolvers successively with the SAME ACL UUID, until it */
/* finds one that works. If we just return the ACL UUID without */
/* checking whether the right manager_type is being asked for, */
/* we’ll only cause an error in the ACL library when it discovers */
/* that the types don’t match up. This will prevent acl_edit from */
/* working. So do the checking here... */
