8a715feb57 Handle multiple AJP adapters during upgrade
In this patch, we ensure we upgrade all AJP adapters with the same
secret value if any are missing. This ensures that both IPv4 and IPv6
adapters have the same secret value, so whichever httpd connects to
will be in sync. This is consistent with what Dogtag does when
provisioning them.

Notably missing from this patch is handling of multiple unrelated AJP
adapters. In an IPA scenario (and default PKI scenario) this shouldn't
be necessary. However, with external load balancing, this might happen.

This patch benefits IPA in the scenario when:

 1. pkispawn runs on an older PKI version (pre-AJP secret, so ~8.2?)
 2. pki gets upgraded to 10.10.1 before IPA can provision a secret,
    resulting in split IPv4/IPv6 adapters -- this would only happen
    on a direct migration from 8.2 -> 8.4
 3. ipa upgrade script then runs to provision an AJP secret value for
    use with both Dogtag and IPA.

Without this patch, only the first (IPv4) adapter would have a secret
value provisioned in the above scenario.

8c2c6f8253 ipa-cert-fix: improve handling of 'pki-server cert-fix' failure
'pki-server cert-fix' has a known and expected failure when the DS
certificate is expired.  'ipa-cert-fix' handles this by
optimistically ignoring the CalledProcessError and continuing when
the DS certificate was up for renewal.

This heuristic is a bit too optimistic.  If 'pki-server cert-fix'
fails due and returns nonzero due to some other, more serious error
(as has been seen in the wild[1]), 'ipa-cert-fix' continues then
fails later with a more confusing error, for example:

    [Errno 2] No such file or directory:
      '/etc/pki/pki-tomcat/certs/27-renewed.crt'

[1] https://bugzilla.redhat.com/show_bug.cgi?id=1930586

Improve the heuristic by also checking whether output files
corresponding ot all of the "extra" certificate that we asked
'ipa-cert-fix' to renew, do indeed exist and are X.509 certificates.

c0e63429b3 Don't double-report any errors from pki-spawn failures
The output from pki-spawn is already displayed to the user
as well as a short traceback so re-displaying the CalledProcess
error provides no value and only provokes confusion,
particularly because it is condensed and includes embedded
newlines.

Re-raise the exception from None so that the traceback is
removed and while there is still an immense traceback from
the admintool class it is significantly shorter than before
and removes:

"During handling of the above exception, another exception occurred"

The handling is in fact expected.

This changes the user-facing installer output from:

  [1/28]: configuring certificate server instance
Failed to configure CA instance: CalledProcessError(Command ['/usr/sbin/pkispawn', '-s', 'CA', '-f', '/tmp/tmpr5x2l0gm', '--debug'] returned non-zero exit status 1: 'INFO: Connecting to LDAP server at ldap://ipa.example.test:389\nINFO: Connecting to LDAP server at ldap://ipa.example.test:389\nDEBUG: Installing Maven dependencies: False\nERROR: KeyError: \'CA\'\n  File "/usr/lib/python3.9/site-packages/pki/server/pkispawn.py", line 575, in main\n    raise KeyError(\'CA\')\n\n')

The output is similarly reduced in the installer log. There is no
reason to acknowledge that a CalledProcessError was raised since
the output is already available and it's just an intermediary.

Hopefully this will encourage users to focus on the logs rather than
the malformed traceback.

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.

214aeb7243 ipaserver/dcerpc: store forest topology as a blob in ipasam
winbindd expects forest topology information blob to find out child
domains. We should store it in LDAP and let ipasam to retrieve it.
In fact, ipasam already supports updating and loading this information
but during 'ipa trust-fetch-domains' we didn't provide it.

Make sure the blob is preserved after it was retrieved and also updated
when we fetch forest topology information.

We want to always use SMB encryption if it is possible on LSA pipe as we

The catch is that older Samba version might not have a way to enforce
this and we need fall back to work with existing connection then.

e157ea1e14 ipaserver/dcerpc.py: use Kerberos authentication for discovery
In FIPS mode we cannot rely on NTLMSSP at all, so we have ensure
Kerberos is used by Samba Python libraries. This is achieved by
requiring credentials objects to always use Kerberos authentication.

Additionally, we have to normalize the principal used to authenticate.
In case it was passed without realm, add forest root domain as a realm.
In case it was passed with NetBIOS domain name, remove it and replace
with a realm. Since we only know about the forest root domain as a
realm, require that for other domains' users a real Kerberos principal
is specified.

cf17b7af5a ipaserver/dcerpc: use Samba-provided trust helper to establish trust
When establishing trust to Active Directory forest, RC4 is used to
encrypt trusted domain object credentials as an application-specific
material in a secure channel based on AES session key.

In FIPS mode it is not possible to use RC4 directly.

Samba 4.14 and backports to 4.13 in Fedora 33+ and RHEL 8.4+ now
provide a helper that wraps LSA RPC call CreateTrustedDomainEx2.
This helper ensures that in FIPS mode we first check that LSA session
key is AES before allowing RC4 use internally in Samba bindings. Thus,
it becomes possible to establish trust to Active Directory forest in
FIPS mode.

Adopt FreeIPA code to use the helper provided by Samba when it is
available. If neither the helper nor unprotected arcfour_encrypt utility
is available from Samba bindings, fail import of the ipaserver.dcerpc
module.

Move actual resolution of UID/GID values for 'ods' entities to the code

up without DNS feature. In particular, 'ods' user and group are created
when 'opendnssec' package is installed and if 'opendnssec' package is
not installed, uninstall fails in OpenDNSSEC Exporter instance
constructor.

We use common pattern of checking the service during uninstall:

 svc = SVCClass()
 if svc.is_configured():
    svc.uninstall()

Thus, service class constructor must not do UID/GID resolution
