1f82d281cc service delegation: allow to add and remove host principals
Service delegation rules and targets deal with Kerberos principals.
As FreeIPA has separate service objects for hosts and Kerberos services,
it is not possible to specify host principal in the service delegation
rule or a target because the code assumes it always operates on Kerberos
service objects.

Simplify the code to add and remove members from delegation rules and
targets. New code looks up a name of the principal in cn=accounts,$BASEDN
as a krbPrincipalName attribute of an object with krbPrincipalAux object
class. This search path is optimized already for Kerberos KDC driver.

To support host principals, the specified principal name is checked to
have only one component (a host name). Service principals have more than
one component, typically service name and a host name, separated by '/'
sign. If the principal name has only one component, the name is
prepended with 'host/' to be able to find a host principal.

The logic described above allows to capture also aliases of both
Kerberos service and host principals. Additional check was added to
allow specifying single-component aliases ending with '$' sign. These
are typically used for Active Directory-related services like databases
or file services.

RN: service delegation rules and targets now allow to specify hosts as
RN: a rule or a target's member principal.

cf4c2c64b0 upgrade: add ipa-ca.$DOMAIN alias to HTTP certificate
For detailed discussion on the purpose of this change and the design
decisions made, see `git log -1 $THIS_COMMIT~3`.

If the HTTP certificate does not have the ipa-ca.$DOMAIN dNSName,
resubmit the certificate request to add the name.  This action is
performed after the tracking request has already been updated.

Note: due to https://pagure.io/certmonger/issue/143, the resubmitted
request, if it does not immediately succeed (fairly likely during
ipa-server-upgrade) and if the notAfter date of the current cert is
still far off (also likely), then Certmonger will wait 7 days before
trying again (unless restarted).  There is not much we can do about
that in the middle of ipa-server-upgrade.

f7c45641fe cert-request: allow ipa-ca.$DOMAIN dNSName for IPA servers
For detailed discussion on the purpose of this change and the design
decisions made, see `git log -1 $THIS_COMMIT~1`.

ACME support requires TLS and we want ACME clients to access the
service via the ipa-ca.$DOMAIN DNS name.  So we need to add the
ipa-ca.$DOMAIN dNSName to IPA servers' HTTP certificates.  To
facilitiate this, add a special case to the cert-request command
processing.  The rule is:

- if the dnsName being validated is "ipa-ca.$DOMAIN"
- and the subject principal is an "HTTP/..." service
- and the subject principal's hostname is an IPA server

Then that name (i.e. "ipa-ca.$DOMAIN") is immediately allowed.
Otherwise continue with the usual dnsName validation.

4cf9c8689f httpinstance: add fqdn and ipa-ca alias to Certmonger request
BACKGROUND:

We are implementing ACME support in FreeIPA (umbrella ticket:
https://pagure.io/freeipa/issue/4751).  ACME is defined in RFC 8555.
HTTPS is REQUIRED (https://tools.ietf.org/html/rfc8555#section-6.1).
Therefore, every FreeIPA server that provides the ACME service
capability must be reachable by HTTPS.

RFC 8555 does not say anything about which port to use for ACME.
The default HTTPS port of 443 is implied.  Therefore, the FreeIPA
ACME service will be reached via the Apache httpd server, which will
be the TLS server endpoint.

As a usability affordance for ACME clients, and as a maintainability
consideration i.e. to allow the topology to change without having to
reconfigure ACME clients, there should be a a single DNS name used
to reach the IPA ACME service.

The question then, is which DNS name to use.

REQUIREMENTS:

Each FreeIPA server that is also an ACME server must:

1. Be reachable via a common DNS name

2. Have an HTTP service certificate with that DNS name as a SAN
   dNSName value

DESIGN CONSIDERATION - WHAT DNS NAME TO USE?:

Some unrelated FreeIPA ACME design decisions provide important
context for the DNS name decision:

- The ACME service will be automatically and unconditionally
  deployed (but not necessarily *enabled*) on all CA servers.

- Enabling or disabling the ACME service will have topology-wide
  effect, i.e. the ACME service is either enabled on all CA
  servers, or disabled on all CA servers.

In a CA-ful FreeIPA deployment there is already a DNS name that
resolves to all CA servers: ``ipa-ca.$DOMAIN``, e.g.
``ipa-ca.example.com``.  It is expected to point to all CA servers
in the deployment, and *only* to CA servers.  If internal DNS is
deployed, the DNS records for ``ipa-ca.$DOMAIN`` are created and
updated automatically.  If internal DNS is not deployed,
administrators are required to maintain these DNS records
themselves.

The ``ipa-ca.$DOMAIN`` alias is currently used for OCSP and CRL
access.  TLS is not required for these applications (and it can
actually be problematic for OCSP).  Enabling TLS for this name
presents some risk of confusion for operators.  For example, if they
see that TLS is available and alter the certificate profiles to
include an HTTPS OCSP URL in the Authority Information Access (AIA)
extension, OCSP-using clients may fail to validate such
certificates.  But it is possible for administrators to make such a
change to the profile, whether or not HTTPS is available.

One big advantage to using the ``ipa-ca.$DOMAIN`` DNS name is that
there are no new DNS records to manage, either in the FreeIPA
implementation or for administrators in external DNS systems.

The alternative approach is to define a new DNS name, e.g.
``ipa-acme.$DOMAIN``, that ACME clients would use.  For internal
DNS, this means the FreeIPA implementation must manage the DNS
records.  This is straightforward; whenever we add or remove an
``ipa-ca.$DOMAIN`` record, also add/remove the ``ipa-acme.$DOMAIN``
record.  But for CA-ful deployments using external DNS, it is
additional work for adminstrators and, unless automated, additional
room for error.

An advantage of using a different DNS name is ``ipa-ca.$DOMAIN`` can
remain inaccessible over HTTPS.  This possibly reduces the risk of
administrator confusion or creation of invalid AIA configuration in
certificate profiles.

Weighing up the advantages and disadvantages, I decided to use the
``ipa-ca.$DOMAIN`` DNS name.

DESIGN CONSIDERATION - CA SERVERS, OR ALL SERVERS?:

A separate decision from which name to use is whether to include it
on the HTTP service certificate for ACME servers (i.e. CA servers)
only, or on all IPA servers.

Combined with the assumption that the chosen DNS name points to CA
servers *only*, there does not seem to be any harm in adding it to
the certificates on all IPA servers.

The alternative is to only include the chosen DNS name on the HTTP
service certificates of CA servers.  This approach entails some
additional complexity:

- If a non-CA replica gets promoted to CA replica (i.e. via
  ``ipa-ca-install``), its HTTP certificate must be re-issued with
  the relevant name.

- ipa-server-upgrade code must consider whether the server is a CA
  replica when validating (and if necessary re-creating) Certmonger
  tracking requests

- IPA Health Check must be made aware of this factor when checking
  certificates and Certmonger tracking requests.

Weighing up the options, I decided to add the common DNS name to the
HTTP service certificate on all IPA servers.  This avoids the
implementation complexity discussed above.

CHANGES IN THIS COMMIT

When (re-)tracking the HTTP certificate, explicitly add the server
FQDN and ipa-ca.$DOMAIN DNS names to the Certmonger tracking request.

Related changes follow in subsequent commits.

2997a74abc Prevent adding IPA objects as external members of external groups
The purpose of external groups in FreeIPA is to be able to reference
objects only existing in trusted domains. These members get resolved
through SSSD interfaces but there is nothing that prevents SSSD from
resolving any IPA user or group if they have security identifiers
associated.

Enforce a check that a SID returned by SSSD does not belong to IPA
domain and raise a validation error if this is the case. This would
prevent adding IPA users or groups as external members of an external
group.

RN: Command 'ipa group-add-member' allowed to specify any user or group
RN: for '--external' option. A stricter check is added to verify that
RN: a group or user to be added as an external member does not come

9eb1be8752 Part2: Don't fully quality the FQDN in ssbrowser.html for Chrome
The web page ssbrowser.html is displayed when the browser doesn't
enable javascript. When js is enabled, the content is taken from
ipaserver/plugins/internal.py.

The commit e4966f9 fixed a string in ssbrowser.html but did not
fix the corresponding string in ipaserver/plugins/internal.py,
resulting in a different page depending on javascript enabled/not
enabled.
This commit makes both contents consistent.

856fdbc183 dnsrecord: Treat empty list arguments correctly
dnsrecord_del fails when one of the record arguments is an empty list:

    AttrValueNotFound("AAAA record does not contain 'None'",)

The problem is caused by the fact that LDAPEntry.__getitem__ returns None
for empty lists. The code in the plugin considers None as a single entry
and maps it to vals = [None].

The patch maps None to empty list.

ba12165eaf lint: Make Pylint-2.4 happy again
This is the first time running Pylint-2.4 over the whole IPA codebase.

The latest Pylint (via the Tox task) checks only:
```
{envsitepackagesdir}/ipaclient \
{envsitepackagesdir}/ipalib \
{envsitepackagesdir}/ipapython
```

, while the distro-Pylint runs over all project but it is not fresh.
That's why these warnings/errors weren't exposed before now.

Concerning `internal error`: a fix was accepted by upstream:
https://github.com/PyCQA/pylint/issues/3245, but wasn't released yet.
Until that is done, Pylint just warns.

edfe95b120 Removed hard-coded default profile subsystem class name
Previously in order to enable the LDAP profile subsystem
the ca_enable_ldap_profile_subsystem() would check the
current value of the profile subsystem class parameter in
CS.cfg. If the parameter was still set to the default value
(i.e. ProfileSubsystem), the code would change it to
LDAPProfileSubsystem.

There is a effort in PKI to clean up the profile subsystem
classes which may require changing the default value for
this parameter. However, this improvement is blocked since
the ca_enable_ldap_profile_subsystem() is implicitly assuming
that the default value will always be ProfileSubsystem.

This patch modifies the code such that instead of checking
for a specific value that needs to be changed, it will check
whether it has the desired value already. This mechanism
will reduce potential conflicts with future PKI improvements.

769180c2c6 Do not renew externally-signed CA as self-signed
Commit 49cf5ec64b fixed a bug that
prevented migration from externally-signed to self-signed IPA CA.
But it introduced a subtle new issue: certmonger-initiated renewal
renews an externally-signed IPA CA as a self-signed CA.

To resolve this issue, introduce the `--force-self-signed' flag for
the dogtag-ipa-ca-renew-agent script.  Add another certmonger CA
definition that calls this script with the `--force-self-signed'
flag.  Update dogtag-ipa-ca-renew-agent to only issue a self-signed
CA certificate if the existing certificate is self-signed or if
`--force-self-signed' was given.  Update `ipa-cacert-manage renew'
to supply `--force-self-signed' when appropriate.

As a result of these changes, certmonger-initiated renewal of an
externally-signed IPA CA certificate will not issue a self-signed
certificate.

e2d69380fb AD user without override receive InternalServerError with API

The fix properly handles ACIError exception received when

$ ipa ping
ipa: ERROR: cannot connect to 'https://master.ipa.com/ipa/json': Unauthorized

2ed5eca762 Reset per-indicator Kerberos policy
When 'ipa krbtpolicy-reset' is called, we need to reset all policy
settings, including per-indicator ones. Per-indicator policy uses
subtyped attributes (foo;bar), the current krbtpolicy-reset code does
not deal with those.

Add support for per-indicator policy reset. It is a bit tricky, as we
need to drop the values to defaults but avoid adding non-per-indicator
variants of the same attributes.

Add test to check that policy has been resetted by observing a new
Kerberos TGT for the user after its policy reset.

if options.force and options.allow_zone_overlap are both false and the

dnsutil.DNSZoneAlreadyExists.

Both issues have been fixed and the deployment with existing name servers

When re-running `ipa-server-install --setup-dns` on already installed
server, we do not get to the check of being already installed because
DNS zone overlap forces us to fail earlier.

Change exception returned for this case from check_zone_overlap() to
return structured information that allows to understand whether we are
finding a conflict with ourselves.

Use the returned information to only fail DNS check at this point if DNS
zone overlap is generated by a different name server than ourselves.
