Add support for configuring the attributes of new principals created via
httpkadmind. This can be done via virtual host-based service
namespaces, which will provide default attributes even if disabled (but
the created principals will not be disabled, naturally), or via
krb5.conf.
Test that we can still do other things after `kadmin list` to make sure
we're not leaving -after listing- the connection in a state where other
operations can't work.
Also, no more sleeps at all in the test.
Any callback of kadm5_iter_principals() that wants to call other kadm5
functions (such as kadm5_get_principal()) needs to do so on a different
kadm5 handle than the one used for kadm5_iter_principals().
This is an attempt to make sure we test realm migration aliases by doing
kinit w/ a hard alias name in a different realm, and that we can get
service tickets for services in the same and other realms some of which
are hard aliases in one direction, and some in the other.
Implement a variation on the op for listing principals where if the
client indicates support for the new variation then we stream the list
instead of collecting it into one reply. This is the server-side
version of the associated, preceding commit:
kadm5: Add online kadm5_iter_principals()
Not sure why we ever needed the run-kadmind-for-one-operation approach
to testing. Anyways, we probably don't. Ditching that and using the
--detach mechanism of daemonization means we don't need to sleep in the
test (except when we need to restart kadmind with different options).
We introduced a notion of soft vs. hard aliases in the previous commit
(hdb: Distinguish soft and hard principal aliases).
This commit corrects existing test cases and adds new test cases.
Soft aliases allow for the configuration of referrals using HDB entries.
Hard aliases are like copies of the aliased HDB entries. These are
useful for renaming principals (and realms).
See the preceding commit.
Add a new method for issuing referrals for entire namespaces of hostnames.
An alias of the form WELLKNOWN/HOSTBASED-NAMESPACE/service/namespace-fqdn@REALM
will cause all requests for host-based principals in the given namespace to be
referred to the given realm.
PACs are included when issuing TGTs, if there is no PAC_ATTRIBUTES buffer
(legacy behavior) or if the attributes buffer indicates the AS client requested
one.
KRB5SignedPath was a Heimdal-specific authorization data element used to
protect the authenticity of evidence tickets when used in constrained
delegation (without a Windows PAC).
Remove this, to be replaced with the Windows PAC which itself now supports
signing the entire ticket in the TGS key.
This was broken with KRB5SignedPath but now that we switch to PAC
we get it fixed without KDC changes, so we can just test it.
See also PR #599 from where these tests were taken.
Add support for GSS-API pre-authentication to the KDC, using a simplified
variation of draft-perez-krb-wg-gss-preauth-02 that encodes GSS-API context
tokens directly in PADATA, and uses FX-COOKIE for state management.
More information on the protocol and implementation may be found in
lib/gssapi/preauth/README.md.
Combined with the synthetic_clients feature, this will allow hosts that
have a PKINIT-worthy client certificate with a SAN with their host
principals to create their own principals and "extract" their host
keytabs. Together with some other PKIX credential bootstrapping
protocol, this can help hosts bootstrap Kerberos host credentials.
This is useful for services that need not be clients. For example, an
untrusted service that need only accept authentication from clients,
but not initiate authentication to other services.
- Don't log "Request from wrong address (ignoring)".
- Add "wrongaddr=yes" kv to final log message.
- Add request and ticket addresses (up to 3) to final log message.
This adds support for using a Heimdal-specific PKIX extension to derive
a maximum Kerberos ticket lifetime from a client's PKINIT certificate.
KDC configuration parameters:
- pkinit_max_life_from_cert_extension
- pkinit_max_life_bound
If `pkinit_max_life_from_cert_extension` is set to true then the
certificate extension or EKU will be checked.
If `pkinit_max_life_bound` is set to a positive relative time, then that
will be the upper bound of maximum Kerberos ticket lifetime derived from
these extensions.
The KDC config `pkinit_ticket_max_life_from_cert` that was added earlier
has been renamed to `pkinit_max_life_from_cert`.
See lib/hx509 and lib/krb5/krb5.conf.5.
This adds a KDC configuration parameter that can be used to indicate
that a PKINIT client's certificate's notAfter overrides the client
principal's HDB entry's max_life. This parameter is a relative time
parameter, and it enables this only if set to a non-zero value (defaults
to zero). The value of this parameter caps the max_life inferred from
the certificate.
