10 * Attention: Not all BIND versions support "ms-self". The instead use
11 * of allow-update { any; }; is another, but less secure possibility.
15 * A rather long description here, as the "ms-self" option does
16 * not appear in any docs yet (it can only be found in the
19 * The short of it is that each host is allowed to update its
20 * own A and AAAA records, when the update request is properly
21 * signed by the host itself.
23 * The long description is (look at the
24 * dst_gssapi_identitymatchesrealmms() call in lib/dns/ssu.c and
25 * its definition in lib/dns/gssapictx.c for details):
27 * A GSS-TSIG update request will be signed by a given signer
28 * (e.g. machine-name$@${REALM}). The signer name is split into
29 * the machine component (e.g. "machine-name") and the realm
30 * component (e.g. "${REALM}"). The update is allowed if the
31 * following conditions are met:
33 * 1) The machine component of the signer name matches the first
34 * (host) component of the FQDN that is being updated.
36 * 2) The realm component of the signer name matches the realm
37 * in the grant statement below (${REALM}).
39 * 3) The domain component of the FQDN that is being updated
40 * matches the realm in the grant statement below.
42 * If the 3 conditions above are satisfied, the update succeeds.

63 # The most recent BIND versions (9.5.0a5 or later) support secure GSS-TSIG
64 # updates. If you are running an earlier version of BIND, or if you do not wish
65 # to use secure GSS-TSIG updates, you may remove the update-policy sections in
66 # both examples above.
