Operations in FIPS mode make impossible use of NTLMSSP when
authenticating to trusted Active Directory domain controllers because
RC4 cipher is not allowed. Instead, Kerberos authentication have to be
used. We switched to enforce Kerberos authentication when communicating
with trusted domains' domain controllers everywhere.
Kerberos library uses system wide configuration which in IPA defaults to
resolving location of KDCs via DNS SRV records. Once trust is
established, SSSD will populate a list of closest DCs and provide them
through the KDC locator plugin. But at the time the trust is established
performing DNS SRV-based discovery of Kerberos KDCs might fail due to
multiple reasons. It might also succeed but point to a DC that doesn't
know about the account we have to use to establish trust.
One edge case is when DNS SRV record points to an unreachable DC,
whether due to a firewall or a network topology limitations. In such
case an administrator would pass --server <server> option to
'ipa trust-add' or 'ipa trust-fetch-domains' commands.
'ipa trust-fetch-domains' runs a helper via oddjobd. This helper was
already modified to support --server option and generated custom
krb5.conf overlay to pin to a specific AD DC. However, this
configuration was removed as soon as we finished talking to AD DCs.
With switch to always use Kebreros to authenticate in retrieval of the
topology information, we have to use the overlay everywhere as well.
Convert the code that generated the overlay file into a context that
generates the overlay and sets environment. Reuse it in other
trust-related places where this matters.
Oddjob helper runs as root and can write to /run/ipa for the krb5.conf
overlay.
Server side of 'ipa trust-add' code calls into ipaserver/dcerpc.py and
runs under ipaapi so can only write to /tmp. Since it is a part of the
Apache instance, it uses private /tmp mounted on tmpfs.

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.

With commit c6644b8566 we default to
create unique credential caches in /run/ipa/ccaches for every client
that connects to IPA with a new session. On F34, mod_auth_gssapi process
running as 'apache' cannot create the ccache in /run/ipa/ccaches because
it has no access rights.
The core of the problem is that we have two different paths to obtaining
a ccache: one where 'apache' running httpd process creates it directly
and one where an internal redirect from 'ipaapi' running httpd process
is happening.
Use SUID and SGID to 'ipaapi'/'ipaapi' and allow 'apache' group to write
to '/run/ipa/ccaches'. This fixes the problem.
Note that we cannot completely remove 'GssapiDelegCcachePerms'. If we'd
do so, mod_auth_gssapi will do redirects and fail.

FreeIPA's Python and C code used different approaches to get the FQDN of
the host. Some places assumed that gethostname() returns a FQDN. Other
code paths used glibc's resolver to resolve the current node name to a
FQDN.
Python code now uses the ipalib.constants.FQDN where a fully qualified
domain name is expected. The variable is initialized only once and avoids
potential DNS lookups.
C code uses a new helper function ipa_gethostfqdn() in util package. The
function implements similar logic as gethostfqdn() except it uses more
modern getaddrinfo(). The result is cached as well.

transparent way, FreeIPA could utilize OpenSSL version of BIND.
