In 2012, ldbm backend in 389-ds started checking entry modification
after running betxnpreop plugins by comparing a number of modifications
before and after. If that number didn't change, it is considered that
plugins didn't modify the list.
ipa-pwd-extop actually removed and re-added modification to ipaNTHash if
it contained 'MagicRegen' value. This did not work since commit
https://pagure.io/389-ds-base/c/6c17ec56076d34540929acbcf2f3e65534060a43
but we were lucky nothing in FreeIPA code actually relied on that except
some code paths in ipasam Samba passdb driver. However, Samba didn't
reach the point where the code was triggered -- until now.
With support to run Samba as a domain member in IPA domain, that code
path is triggered for Kerberos service principals of domain members
(cifs/client.example.test, ...) and NT hash extraction from Kerberos
keys does not work.

With system-wide crypto policy in use, arcfour-hmac encryption type
might be removed from the list of permitted encryption types in the MIT
Kerberos library. Applications aren't prevented to use the arcfour-hmac
enctype if they operate on it directly.
Since FreeIPA supported and default encryption types stored in LDAP, on
the server side we don't directly use a set of permitted encryption
types provided by the MIT Kerberos library. However, this set will be
trimmed to disallow arcfour-hmac and other weaker types by default.
While the arcfour-hmac key can be generated and retrieved, MIT Kerberos
library will still not allow its use in Kerberos protocol if it is not
on the list of permitted encryption types. We only need this workaround
to allow setting up arcfour-hmac key for SMB services where arcfour-hmac
key is used to validate communication between a domain member and its
domain controller. Without this fix it will not be possible to request
setting up a machine account credential from the domain member side. The
latter is needed for Samba running on IPA client.
Thus, extend filtering facilities in ipa-pwd-extop plugin to explicitly
allow arcfour-hmac encryption type for SMB services (Kerberos principal
name starts with cifs/).

Samba 4.10 moved away to private libraries two functions we used to
convert a binary SID structre to strings:
- sid_talloc_string()
- sid_string_dbg()
We already used libsss_idmap to convert textual representation of SIDs
to a binary one, use the reverse function too.
libsss_idmap code operates on talloc structures, so we need to adopt a
bit a place where sid_string_dbg() was used because it assumed a static
buffer was provided by sid_string_dbg().
Finally, sid_talloc_string()'s replacement moves allocated memory to the
right context so that a memory will be freed earlier. Our SSSD idmap
context is a long-living one while in all cases where we were using
sid_talloc_string() we free the context much earlier.

> For example, the init function should not attempt to perform an

This init method fills a structure containing the configuration of
allowed authentication types. As the method is called too early, the
method does not find any suffix and leaves the structure empty.
Subsequent calls find an empty structure and take the default values
(for authentication methods, the default is 1 = password).
Because of that, the code consider that the global configuration defines
password authentication method, and in this case it is allowed to delete
a user's last otp token.
The fix implements a SLAPI_PLUGIN_START_FN method that will be called

Currently there is already code to make sure that after trust is established an
AS-REQ of the local HTTP principal causes a refresh of the internal structures
holding the information about the trusted domains.
But this refreshes only the data of the current krb5kdc worker process on the
local host. Other workers and the KDCs on other hosts will update the data
eventually when a request with a principal from a trusted realm is handled.
During this phase, which might last quite long if remote principals are only
handled rarely, TGTs for local principals might or might not contain a PAC
because the decision if a PAC should be added or not is based on the
information about trusted domains. Since the PAC is needed to access services
on the AD side this access might fail intermittently depending which worker
process on which host is handling the request. This might e.g. affect SSSD
running on the IPA server with two-way trust.
To fix this this patch calls ipadb_reinit_mspac() whenever a PAC is needed but
without the 'force' flag so that the refresh will only happen if it wasn't
called recently (currently not more often than once a minute).
An alternative might be to do the refresh only when processing cross-realm TGT
requests. But this would be already too late because the local principal asking
for a cross-realm ticket would not have a PAC and hence the first attempt will
still fail due to the missing PAC. And injecting the PAC in the cross-realm TGT
while there is none in the requesting ticket does not sound right.

Refactor nsswitch operations in ipa-extdom-extop plugin to allow use
of timeout-enabled nsswitch calls provided by libsss_nss_idmap.
Standard POSIX nsswitch API has no way to cancel requests which may
cause ipa-extdom-extop requests to hang far too long and potentially
exhaust LDAP server workers. In addition, glibc nsswitch API iterates
through all nsswitch modules one by one and with multiple parallel
requests a lock up may happen in an unrelated nsswitch module like
nss_files.so.2.
A solution to the latter issue is to directly load nss_sss.so.2 plugin
and utilize it. This, however, does not solve a problem with lack of
cancellable API.
With SSSD 1.16.1, libsss_nss_idmap provides a timeout-enabled variant of
nsswitch API that is directly integrated with SSSD client side machinery
used by nss_sss.so.2. As result, this API can be used instead of loading
nss_sss.so.2 directly.
To support older SSSD version, both direct loading of nss_sss.so.2 and
new timeout-enabled API are supported by this changeset. An API to
abstract both is designed to be a mix between internal glibc nsswitch
API and external nsswitch API that libsss_nss_idmap mimics. API does not
expose per-call timeout. Instead, it allows to set a timeout per
nsswitch operation context to reduce requirements on information
a caller has to maintain.
A choice which API to use is made at configure time.
In order to test the API, a cmocka test is updated to explicitly load
nss_files.so.2 as a backend. Since use of nss_sss.so.2 would always
depend on availablility of SSSD, predictable testing would not be
possible without it otherwise. Also, cmocka test does not use
nss_wrapper anymore because nss_wrapper overrides higher level glibc
nsswitch API while we are loading an individual nsswitch module
directly.
As result, cmocka test overrides fopen() call used by nss_files.so.2 to
load /etc/passwd and /etc/group. An overridden version changes paths to
/etc/passwd and /etc/group to a local test_data/passwd and
test_data/group. This way we can continue testing a backend API for
ipa-extdom-extop with the same data as with nss_wrapper.

Slots in HSM are not assigned statically, we have to chose proper
slot from token label.
Softhsm i2.2.0 changed this behavior and now slots can change over
time (it is allowed by pkcs11 standard).
Changelog:
* created method get_slot() that returns slot number from
used label
* replaces usage of slot in __init__ method of P11_Helper
with label
* slot is dynamically detected from token label before
session is opened
* pkcs11-util --init-token now uses '--free' instead '--slot'
which uses first free slot (we don't care about slot numbers
anymore)

When a trusted domain entry is created, the uidNumber attribute is created
but not the gidNumber attribute. This causes samba to log
Failed to find a Unix account for DOM-AD$
because the samu structure does not contain a group_sid and is not put
in the cache.
The fix creates the gidNumber attribute in the trusted domain entry,
and initialises the group_sid field in the samu structure returned
by ldapsam_getsampwnam. This ensures that the entry is put in the cache.
Note that this is only a partial fix for 6660 as it does not prevent

Certificates can be assigned to multiple user so the extdom plugin must
use sss_nss_getlistbycert() instead of sss_nss_getnamebycert() and
return a list of fully-qualified user names.
Due to issues on the SSSD side the current version of lookups by
certificates didn't work at all and the changes here won't break
existing clients.

DAL version 6.0 removed support for a callback to free principal.
This broke KDB drivers which had complex e_data structure within
the principal structure. As result, FreeIPA KDB driver was leaking
memory with DAL version 6.0 (krb5 1.15).
DAL version 6.1 added a special callback for freeing e_data structure.
See details at krb5/krb5#596
Restructure KDB driver code to provide this callback in case
we are built against DAL version that supports it. For DAL version
prior to 6.0 use this callback in the free_principal callback to
tidy the code.
Use explicit KDB version dependency in Fedora 26+ via BuildRequires.
With new DAL version, freeipa package will fail to build and
we'll have to add a support for new DAL version explicitly.
