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.
