Welcome the new krb5-121 (1.21) from MIT.
krb5-119 is now deprecated and scheduled for removal a year from
now.
|
|
In addition, deprecate krb5-116 to retire one year after the release
of krb5-118: Feb 12, 2021.
Major changes in 1.18 (2020-02-12)
==================================
Administrator experience:
* Remove support for single-DES encryption types.
* Change the replay cache format to be more efficient and robust.
Replay cache filenames using the new format end with ".rcache2" by
default.
* setuid programs will automatically ignore environment variables that
normally affect krb5 API functions, even if the caller does not use
krb5_init_secure_context().
* Add an "enforce_ok_as_delegate" krb5.conf relation to disable
credential forwarding during GSSAPI authentication unless the KDC
sets the ok-as-delegate bit in the service ticket.
* Use the permitted_enctypes krb5.conf setting as the default value
for default_tkt_enctypes and default_tgs_enctypes.
Developer experience:
* Implement krb5_cc_remove_cred() for all credential cache types.
* Add the krb5_pac_get_client_info() API to get the client account
name from a PAC.
Protocol evolution:
* Add KDC support for S4U2Self requests where the user is identified
by X.509 certificate. (Requires support for certificate lookup from
a third-party KDB module.)
* Remove support for an old ("draft 9") variant of PKINIT.
* Add support for Microsoft NegoEx. (Requires one or more third-party
GSS modules implementing NegoEx mechanisms.)
* Honor the transited-policy-checked ticket flag on application
servers, eliminating the requirement to configure capaths on
servers in some scenarios.
User experience:
* Add support for "dns_canonicalize_hostname=fallback""`, causing
host-based principal names to be tried first without DNS
canonicalization, and again with DNS canonicalization if the
un-canonicalized server is not found.
* Expand single-component hostnames in host-based principal names when
DNS canonicalization is not used, adding the system's first DNS
search path as a suffix. Add a "qualify_shortname" krb5.conf
relation to override this suffix or disable expansion.
Code quality:
* The libkrb5 serialization code (used to export and import krb5 GSS
security contexts) has been simplified and made type-safe.
* The libkrb5 code for creating KRB-PRIV, KRB-SAFE, and KRB-CRED
messages has been revised to conform to current coding practices.
* The test suite has been modified to work with macOS System Integrity
Protection enabled.
* The test suite incorporates soft-pkcs11 so that PKINIT PKCS11
support can always be tested.

KRB5 1.16 releases.
Major changes in 1.16 (2017-12-05)
==================================
Administrator experience:
* The KDC can match PKINIT client certificates against the
"pkinit_cert_match" string attribute on the client principal entry,
using the same syntax as the existing "pkinit_cert_match" profile
option.
* The ktutil addent command supports the "-k 0" option to ignore the
key version, and the "-s" option to use a non-default salt string.
* kpropd supports a --pid-file option to write a pid file at startup,
when it is run in standalone mode.
* The "encrypted_challenge_indicator" realm option can be used to
attach an authentication indicator to tickets obtained using FAST
encrypted challenge pre-authentication.
* Localization support can be disabled at build time with the
--disable-nls configure option.
Developer experience:
* The kdcpolicy pluggable interface allows modules control whether
tickets are issued by the KDC.
* The kadm5_auth pluggable interface allows modules to control whether
kadmind grants access to a kadmin request.
* The certauth pluggable interface allows modules to control which
PKINIT client certificates can authenticate to which client
principals.
* KDB modules can use the client and KDC interface IP addresses to
determine whether to allow an AS request.
* GSS applications can query the bit strength of a krb5 GSS context
using the GSS_C_SEC_CONTEXT_SASL_SSF OID with
gss_inquire_sec_context_by_oid().
* GSS applications can query the impersonator name of a krb5 GSS
credential using the GSS_KRB5_GET_CRED_IMPERSONATOR OID with
gss_inquire_cred_by_oid().
* kdcpreauth modules can query the KDC for the canonicalized requested
client principal name, or match a principal name against the
requested client principal name with canonicalization.
Protocol evolution:
* The client library will continue to try pre-authentication
mechanisms after most failure conditions.
* The KDC will issue trivially renewable tickets (where the renewable
lifetime is equal to or less than the ticket lifetime) if requested
by the client, to be friendlier to scripts.
* The client library will use a random nonce for TGS requests instead
of the current system time.
* For the RC4 string-to-key or PAC operations, UTF-16 is supported
(previously only UCS-2 was supported).
* When matching PKINIT client certificates, UPN SANs will be matched
correctly as UPNs, with canonicalization.
User experience:
* Dates after the year 2038 are accepted (provided that the platform
time facilities support them), through the year 2106.
* Automatic credential cache selection based on the client realm will
take into account the fallback realm and the service hostname.
* Referral and alternate cross-realm TGTs will not be cached, avoiding
some scenarios where they can be added to the credential cache
multiple times.
* A German translation has been added.
