Major changes in 1.19 (2021-02-01)
----------------------------------
Administrator experience:
* When a client keytab is present, the GSSAPI krb5 mech will refresh
credentials even if the current credentials were acquired manually.
* It is now harder to accidentally delete the K/M entry from a KDB.
Developer experience:
* gss_acquire_cred_from() now supports the "password" and "verify"
options, allowing credentials to be acquired via password and
verified using a keytab key.
* When an application accepts a GSS security context, the new
GSS_C_CHANNEL_BOUND_FLAG will be set if the initiator and acceptor
both provided matching channel bindings.
* Added the GSS_KRB5_NT_X509_CERT name type, allowing S4U2Self
requests to identify the desired client principal by certificate.
* PKINIT certauth modules can now cause the hw-authent flag to be set
in issued tickets.
* The krb5_init_creds_step() API will now issue the same password
expiration warnings as krb5_get_init_creds_password().
Protocol evolution:
* Added client and KDC support for Microsoft's Resource-Based
Constrained Delegation, which allows cross-realm S4U2Proxy requests.
A third-party database module is required for KDC support.
* kadmin/admin is now the preferred server principal name for kadmin
connections, and the host-based form is no longer created by
default. The client will still try the host-based form as a
fallback.
* Added client and server support for Microsoft's KERB_AP_OPTIONS_CBT
extension, which causes channel bindings to be required for the
initiator if the acceptor provided them. The client will send this
option if the client_aware_gss_bindings profile option is set.
User experience:
* kinit will now issue a warning if the des3-cbc-sha1 encryption type
is used in the reply. This encryption type will be deprecated and
removed in future releases.
* Added kvno flags --out-cache, --no-store, and --cached-only
(inspired by Heimdal's kgetcred).
