"Kerberos principal expiration" is set in UTC and when server is in
different timezone, the time difference between timezone is respected by
the IPA server/client for Kerberos authentication.
The problem is due to mktime() assuming default time zone but since we
parse the time using Zulu (UTC+0) timezone, mktime() forces current time
zone offset added.
The method is using mktime() and comparing to the current time obtained
with time(NULL). According to its man page, mktime is considering the
time as local time:
The mktime() function converts a broken-down time structure, expressed
as local time, to calendar time representation.
Instead mktime() we should use timegm(). The problem is that it is
non-standard GNU extension and it is recommended (in the man page for
timegm(3)) to avoid its use. An alternative is to set TZ=UTC, call
mktime(), unset TZ, but since we are running in a multi-threaded
environment this is problematic.
On the other hand, we already rely on GNU extensions and enable them
with -D_DEFAULT_SOURCE=1, so use of timegm() is enabled already.
The fix, therefore, is to use timegm() instead of mktime() in
daemons/ipa-slapi-plugins/ipa-pwd-extop/prepost.c in two places where we
first do 'strptime()' with Zulu time zone (in ipapwd_pre_bind() and
ipapwd_write_krb_keys()).

Unify code in client referrals part to do the same and use krb5 API to

An enterprise principal is typically "name@SOMEREALM@REALM", but any

re-parse it again with default realm values, to get our realm

Previously, FreeIPA only allowed to issue PAC record in a ticket
for the following principal types:
- for IPA users
- for a host principal of one of IPA masters
- for a cifs/ or HTTP/ service on one of IPA masters
To allow S4U2Self operations over trust to AD, an impersonating service
must have PAC record in its TGT to be able to ask AD DCs for a S4U2Self
ticket. It means any IPA service performing S4U2Self would need to have
PAC record and the constraints above prevent it from doing so.
However, depending on whether the service or host principal belongs to
one of IPA masters, we need to set proper primary RID to 516 (domain

Finally, in PAC signing we have to take the realm into account as well

following actions:
- obtain a TGT ticket for a user principal using supplied password
- import existing TGT from a default credentials cache
Once a user TGT is available, the utility will attempt to acquire a service

service application.
If establishing context succeeds, MS-PAC content of the service ticket
will be printed out.
2. S4U2Self protocol transition
In protocol transition case a service application obtains own TGT using
a key from the keytab and then requests a service ticket to itself in
the name of the user principal, performing S4U2Self request.
If accepting this service ticket succeeds, MS-PAC content of the service
ticket will be printed out.
If KDC does not support or rejects issuing MS-PAC record for a user, an

NIST SP 800-63-3B sets a recommendation to have password length upper bound limited in A.2:
https://pages.nist.gov/800-63-3/sp800-63b.html#appA
Users should be encouraged to make their passwords as lengthy as they
want, within reason. Since the size of a hashed password is independent
of its length, there is no reason not to permit the use of lengthy
passwords (or pass phrases) if the user wishes. Extremely long passwords
(perhaps megabytes in length) could conceivably require excessive
processing time to hash, so it is reasonable to have some limit.
FreeIPA already applied 256 characters limit for non-random passwords
set through ipa-getkeytab tool. The limit was not, however, enforced in
other places.
MIT Kerberos limits the length of the password to 1024 characters in its
tools. However, these tools (kpasswd and 'cpw' command of kadmin) do not
differentiate between a password larger than 1024 and a password of 1024
characters. As a result, longer passwords are silently cut off.
To prevent silent cut off for user passwords, use limit of 1000
characters.
Thus, this patch enforces common limit of 1000 characters everywhere:
- LDAP-based password changes
- LDAP password change control
- LDAP ADD and MOD operations on clear-text userPassword
- Keytab setting with ipa-getkeytab
- Kerberos password setting and changing

With commit 15ff9c8 a check was removed and as a result Kerberos keys
are unconditionally added to the user entry struct if they are
available. As a result the password related pre-authentication methods
PA-ENC-TIMESTAMP and PA-ETYPE-INFO2 are advertised in the NEEDED_PREAUTH
reply to an AS_REQ.
With respect to the KDC policies this does not matter much because if
password authentication is disabled for the given principal the policy
will reject the AS_REQ if the user tries password authentication. This
is possible because with commit 15ff9c8 kinit will ask for a password if
called without any additional options (e.g. armor ticket or PKINIT
identity). Before 15ff9c8 was committed it just failed with 'kinit:
Pre-authentication failed: Invalid argument while getting initial
credentials' because no suitable pre-authentication method was
available. This is the same behavior as if no password was set for the
given principal.
But with this change SSSD fails to detect the available authentication
types for the given principal properly. As described in
https://docs.pagure.org/SSSD.sssd/design_pages/prompting_for_multiple_authentication_types.html
SSSD uses the MIT Kerberos responder interface to determine the
available authentication methods for the principal and does not check
the ipaUserAuthType LDAP attribute. As a result if a user has 2FA (otp)
authentication configured, which implies that a password is set as the
first factor, the responder interface will always indicate that password
authentication is available even if only opt is enabled for the user.
In this case SSSD will use a prompting which indicates that the second
factor might be optional. Additionally if prompting the user directly is
not possible (e.g. ssh with ChallengeResponseAuthentication /
KbdInteractiveAuthentication disabled) the single string entered by the
user will always be assumed as a password and not as a combination of
password and otp-token value. As a consequence authentication will
always fail because password authentication is disabled for the user and
since SSSD does not do try-and-error 2FA is not tried.
This patch add back the check so that if password authentication is not
available for the principal the Kerberos will not be added to the entry
struct and the KDC will not advertise PA-ENC-TIMESTAMP or
PA-ETYPE-INFO2. If you think this is wrong and the behavior added by
15ff9c8 should be preferred SSSD handing of the available authentication
types must be extended to read ipaUserAuthType as well to restore the
user experience with respect to 2FA prompting and ssh behavior.
