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.
- Formalize the TYPE:collection_name:subsidiary_name naming scheme for
ccaches in ccache collections
- KEYRING: ccaches are weird because they have one more optional field: the
"anchor", so rather than just assume a naming convention everywhere, we
add new functions as well
- Add krb5_cc_{resolve,default}_sub() that allows one to specify a
"subsidiary" ccache name in a collection separately from the
collection name
- Add krb5_cc_{resolve,default}_for() which take a principal name,
unparse it, and use it as the subsidiary ccache name (with colons
replaced)
- Make kinit use the new interfaces
- Add missing DIR ccache iteration functionality
- Revamps test_cc
- Add krb5_cc_get_collection() and krb5_cc_get_subsidiary()
- Bump the ccops SPI version number
- Add gss_store_cred_into2()
- Make MEMORY:anonymous not linked into the global MEMORY ccache
collection, and uses this for delegated cred handles
TBD:
- Split this up into a krb5 change and gss mech_krb5 change?
- Add krb5_cc_init_and_store() utility, per Greg's suggestion?
The --connect-to option is much nicer and better than --resolve for testing,
but for testing against localhost --resolve is good enough and available in
older versions of curl.
