Not without a bit of work.  Add a user to your password file with
a uid >= 65536 and pwd_mkdb will whine about a bad entry.

The uid value is limited to 16 bits for compatibility with older
*nix password files and NIS.  This can be changed/fixed if backwards
compatibility is of no interest.

These code fragments are from -stable.

pwd_mkdb/pw_scan.c:94  fragment from pw_scan()

        if (id > USHRT_MAX) {
                warnx("%s > max gid value (%d)", p, USHRT_MAX);
                return (0);
        }


pwd_mkdb/pwd_mkdb.c:385  fragment from scan()

if (!pw_scan(line, pw)) {
                warnx("at line #%d", lcnt);
fmt:            errno = EFTYPE; /* XXX */
                error(pname);
        }

There may be some NIS issues that need to be addressed also.  I
didn't look at that code.
