You're getting this due to the error code being returned in errno
not being one that Samba expects. Here's the underlying code:

       ret = quotactl(path, cmd, id, qblk);
        if (ret == -1) {
                /* ENOTSUP means quota support is not compiled in. EINVAL
                 * means that quotas are not configured (commonly).
                 */
                if (errno != ENOTSUP && errno != EINVAL) {
                        DEBUG(0, ("failed to %s quota for %s ID %u on %s: %s\n",
                                    (cmd & QCMD(Q_GETQUOTA, 0)) ? "get" : "set",
                                    (cmd & QCMD(0, GRPQUOTA)) ? "group" : "user",
                                    (unsigned)id, path, strerror(errno)));
                }


Looks like your system is returning ENOENT here in errno, not ENOTSUP or EINVAL.
