Since November 2020, Active Directory KDC generates a new type of
signature as part of the PAC. It is called "ticket signature", and is
generated based on the encrypted part of the ticket. The presence of
this signature is not mandatory in order for the PAC to be accepted for
S4U requests.
However, the behavior is different for MIT krb5. Support was added as
part of the 1.20 release, and this signature is required in order to
process S4U requests. Contrary to the PAC extended KDC signature, the
code generating this signature cannot be isolated and backported to
older krb5 versions because this version of the KDB API does not allow
passing the content of the ticket's encrypted part to IPA.
This is an issue in gradual upgrade scenarios where some IPA servers
rely on 1.19 and older versions of MIT krb5, while others use version
1.20 or newer. A service ticket that was provided by 1.19- IPA KDC will
be rejected when used by a service against a 1.20+ IPA KDC for S4U
requests.
On Fedora, CentOS 9 Stream, and RHEL 9, when the krb5 version is 1.20 or
newer, it will include a downstream-only update adding the
"optional_pac_tkt_chksum" KDB string attribute allowing to tolerate the
absence of PAC ticket signatures, if necessary.
This commit adds an extra step during the installation and update
processes where it adds a "pacTktSignSupported" ipaConfigString
attribute in "cn=KDC,cn=[server],cn=masters,cn=ipa,cn=etc,[basedn]" if
the MIT krb5 version IPA what built with was 1.20 or newer.
This commit also set "optional_pac_tkt_chksum" as a virtual KDB entry
attribute. This means the value of the attribute is not actually stored
in the database (to avoid race conditions), but its value is determined
at the KDC starting time by search the "pacTktSignSupported"
ipaConfigString in the server list. If this value is missing for at
least of them is missing, enforcement of the PAC ticket signature is
disabled by setting "optional_pac_tkt_chksum" to true for the local
realm TGS KDB entry.
For foreign realm TGS KDB entries, the "optional_pac_tkt_chksum" virtual
string attribute is set to true systematically, because, at least for
now, trusted AD domains can still have PAC ticket signature support
disabled.
Given the fact the "pacTktSignSupported" ipaConfigString for a single
server is added when this server is updated, and that the value of
"optional_pac_tkt_chksum" is determined at KDC starting time based on
the ipaConfigString attributes of all the KDCs in the domain, this
requires to restart all the KDCs in the domain after all IPA servers
were updated in order for PAC ticket signature enforcement to actually
take effect.

In November 2022, Microsoft introduced a new PAC signature type called
"extended KDC signature" (or "full PAC checksum"). This new PAC
signature will be required by default by Active Directory in July 2023
for S4U requests, and opt-out will no longer be possible after October
2023.
Support for this new signature type was added to MIT krb5, but it relies
on the new KDB API introduced in krb5 1.20. For older MIT krb5 versions,
the code generating extended KDC signatures cannot be backported as it
is without backporting the full new KDB API code too. This would have
too much impact to be done.
As a consequence, krb5 packages for Fedora 37, CentOS 8 Stream, and RHEL
8 will include a downstream-only update adding the
krb5_pac_full_sign_compat() function, which can be used in combination
with the prior to 1.20 KDB API to generate PAC extended KDC signatures.

If a cert-find fails on the CA side we get a Message tag
containing a string describing the failure plus the java stack
trace. Pull out the first part of the message as defined by the
first colon and include that in the error message returned to
the user.
The new message will appear as:
$ ipa cert-find
ipa: ERROR: Certificate operation cannot be completed: Unable to search for certificates (500)
vs the old generic message:
ipa: ERROR: Certificate operation cannot be completed: Unable to communicate with CMS (500)
This can be reproduced by setting nssizelimit to 100 on the
pkidbuser. The internal PKI search returns err=4 but the CA
tries to convert all values into certificates and it fails. The
value needs to be high enough that the CA can start but low
enough that you don't have to create hundreds of certificates

cert-find is a rather complex beast because it not only
looks for certificates in the optional CA but within the
IPA LDAP database as well. It has a process to deduplicate
the certificates since any PKI issued certificates will
also be associated with an IPA record.
In order to obtain the data to deduplicate the certificates
the cert from LDAP must be parser for issuer and serial number.
ipaldap has automation to determine the datatype of an
attribute and will use the python-cryptography engine to
decode a certificate automatically if you access
entry['usercertificate'].
The downside is that this is comparatively slow. Here is the
parse time in microseconds:
OpenSSL.crypto 175
pyasn1 1010
python-cryptography 3136
The python-cryptography time is fine if you're parsing one
certificate but if the LDAP search returns a lot of certificates,
say in the thousands, then those microseconds add up quickly.
In testing it took ~17 seconds to parse 5k certificates.
It's hard to overstate just how much better the cryptography
Python interface is. In the case of OpenSSL really the only
certificate fields easily available are serial number, subject
and issuer. And the subject/issuer are in the OpenSSL reverse
format which doesn't compare nicely to the cryptography format.
The DN module can correct this.
Fortunately for cert-find we only need serial number and issuer,
so the OpenSSL module fine. It takes ~2 seconds.
pyasn1 is also relatively faster but switch to it would require
subtantially more effort for less payback.
cert-find when there are a lot of certificates has been
historically slow. It isn't related to the CA which returns
large sets (well, 5k anyway) in a second or two. It was the
LDAP comparision adding tens of seconds to the runtime.
CLI times from before and after:
original:
-------------------------------
Number of entries returned 5011
-------------------------------
real 0m21.155s
user 0m0.835s
sys 0m0.159s
using OpenSSL:
real 0m5.747s
user 0m0.864s
sys 0m0.148s
OpenSSL is forcibly lazy-loaded so it doesn't conflict with
python-requests. See ipaserver/wsgi.py for the gory details.
