When dnssec role is removed from the local node, the uninstaller
creates a new replica key and marks the older replica keys as disabled
(both in the local HSM and in LDAP).
If ipa-ods-exporter runs in the middle of this operation, the old replica
key may be disabled in the local HSM but not yet in LDAP and
ipa-ods-exporter believes that it is a new replica key that needs to be
imported from LDAP to local hsm. The op fails as there is already the key
in the local HSM.
The error can be ignored, ipa-ods-exporter simply needs to log a warning.

When a master key is missing from the local HSM, ipa-ods-exporter crashes.
This can happen when the DNSSEC master role is moved from one node to
another with the following scenario:
- install server1 with dns + dnssec
- install server2 without dns
- disable dnssec from server1
- install dns + dnssec on server2
With the above scenario, server2 never had the opportunity to get
the master key (this happens only when the replica is already
configured as DNS server and has put its public replica key in LDAP +
the current DNSSEC master wraps its master key with the replica key).
ipa-ods-exporter can only log an error instead of crashing.

ipasam already implemented retrieval of groups for MS-SAMR calls.
However, it did not have implementation of a group retrieval for the
path of lookup_name() function in Samba. The lookup_name() is used in
many places in smbd and winbindd.
With this change it will be possible to resolve IPA groups in Windows UI
(Security tab) and console (net localgroup ...). When Global Catalog
service is enabled, it will be possible to search for those groups as
well.
In Active Directory, security groups can be domain, domain local, local
and so on. In IPA, only domain groups exposed through ipasam because
SID generation plugin only supports adding SIDs to POSIX groups and
users. Thus, non-POSIX groups are not going to have SIDs associated and
will not be visible in both UNIX and Windows environments.
Group retrieval in Samba is implemented as a mapping between NT and
POSIX groups. IPA doesn't have explicit mapping tables. Instead, any
POSIX group in IPA that has a SID associated with it is considered a
domain group for Samba.
Finally, additional ACI is required to ensure attributes looked up by
ipasam are always readable by the trust agents.

This fixes the case where an account is locked on one or more servers
and the password is reset by an administrator. The account would
remain locked on those servers for the duration of the lockout.
This is done by setting krbLastAdminUnlock to the current date and
time. The lockout plugin will see this and unlock the account. Since
the value should be replicated along with the password any server
that has the new password will also be unlocked.
This does incur an additional attribute that must be replicated,
whether it is needed or not, but since lockout is computed
per-server this is the only guaranteed way to be sure that the
account will be unlocked everywhere.
My original thought was to grab password replication events and detect
whether the user was locked out and unlock them. On any given server
you can only know if the user is locked out on that server by
computing it. Doing this would require generalizing the lockout code
so it could be computed on password change. krbLastFailedAuth could
be wiped which would unlock the account on that master (the attribute
is not replicated by default).
So it is complexity vs additional replication. Assuming that admin
reset is relatively rare let's start with that. This doesn't lock
us into this solution for the future.
We could set this attribute on user-driven password changes as
well but the original ask and my thinking are that if you forgot
your password and got locked out, how can you change it yourself?
Upon reflection I guess a user could fat-finger it a bunch of times
against one IPA server then have a revelation and log in against a
different server. So they would still be locked out for the duration
on the first one. I'm not sure the extra replication is worth it for
user-generated password changes or that users would be saavy enough
to try another server for the change.

[MS-ADTS] 6.1.6.9.3.2 requires msDS-TrustForestTrustInfo attribute of

One side-effect of those rules is that list of UPN suffixes reported
through the netr_DsRGetForestTrustInformation function is dynamically
filtered to deduplicate subordinate suffixes.
It means that if list of UPN suffixes contains the following top level
names (TLNs):
fabrikam.com
sub.fabrikam.com
then netr_DsRGetForestTrustInformation would only return 'fabrikam.com'
as the TLN, fully filtering 'sub.fabrikam.com'.
IPA KDB driver used exact comparison of the UPN suffixes so any
subordinate had to be specified exactly.
Modify logic so that if exact check does not succeed, we validate a
realm to test being a subordinate of the known UPN suffixes. The
subordinate check is done by making sure UPN suffix is at the end of the
test realm and is immediately preceded with a dot.
Because the function to check suffixes potentially called for every
Kerberos principal, precalculate and cache length for each UPN suffix at
the time we retrieve the list of them.

two cannot be used in build environment.
nss_files.so.2 always tries to open /etc/passwd and /etc/group. In past, we
overloaded 'fopen()' to change the path to opened file but this stops working
after glibc consolidate file opening in nss_files with the code starting at
https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=299210c1fa67e2dfb564475986fce11cd33db9ad,
this method is not usable anymore and builds against glibc 2.31.9000+ fail in
cmocka unit test execution in Rawhide.
Apply an alternative approach that uses a new user namespace to unshare the
test from its parent and chroot to the test data where expected /etc/passwd and
/etc/group are provided. This method works only on Linux, thus only run the
unit test on Linux.
In case unshare() or chroot() fail, we have to skip tests that use
nss_files.so.2.

"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()).
