08d7209828 baseldap: allow rejecting unknown objects instead of adding to an external attr
IPA traditionally allowed to add names not found in IPA LDAP to external
attributes. This is used to allow, for example, a local system user or
group be present in a SUDO rule.

With membership validator, we can actually check validity of the names
against both IPA users/groups and users/groups from trusted domains.
If in future we decide to reject a local system's objects, then all it
would take is to switch reject_failures to True.

349322e3fb sudorule runAs: allow to add users and groups from trusted domains directly
Allow specifying AD users and groups from trusted Active Directory
forests in `ipa sudorule-add/remove-runasuser/runasgroup` family of

IPA provides 'ipasudorunasextuser' and 'ipasudorunasextusergroup' LDAP
attributes to record 'external' objects referenced in SUDO rules for
specifying the target user and group to run the commands allowed in the
SUDO rule.

Use member type validators to 'ipa sudorule-add/remove-runasuser/runasgroup'
family of commands and rely on member type validators from 'idviews'
plugin to resolve trusted objects.

Referencing fully qualified names for users and groups from trusted
Active Directory domains in IPA SUDOERs schema attributes is supported

5fae809d92 baseldap: when adding external objects, differentiate between them and failures
It was possible to add external members without any validation. Any
object that was not found in IPA LDAP was considered an external object
and a command such as sudorule could have added it to the list of values
for externalUser attribute.

With member validator support, real external members from trusted
domains can be differentiated from the objects that were not found in
IPA and in trusted domains.

Use information from the ID Views plugin to treat external objects
accordingly. Not found objects will be part of the error messaging
instead.

172e4b9770 baseldap: refactor validator support in add_external_pre_callback
baseldap.py:add_external_pre_callback() allows to redefine validators
used to validate member names. Originally this was done to allow
hostname validation and reused default validators associated with other
parameter types.

Provide extension of the validator callbacks to allow fine grained
validation strategy. This is helpful in case we want to apply an
alternative validation strategy in case default validator fails.

New validators can be added to 'member_validator' registry in a similar
way to how API objects are registered:

from .baseldap import member_validator

@member_validator(membertype='foo')
def my_new_validator(ldap, dn, keys, options, value):
    <validate value here>

Arguments passed to the validator are arguments passed to the
add_external_pre_callback() augmented with the value to validate.

can be used in order to be compatible with dnspython 1.16 and 2.0.

49e643783d dnspython: Add compatibility shim
`dnspython` 2.0.0 has many changes and several deprecations like:

```
> dns.resolver.resolve() has been added, allowing control of whether
search lists are used. dns.resolver.query() is retained for backwards
compatibility, but deprecated. The default for search list behavior can
be set at in the resolver object with the use_search_by_default
parameter. The default is False.

> dns.resolver.resolve_address() has been added, allowing easy
address-to-name lookups.
```

The new class `DNSResolver`:
- provides the compatibility layer
- defaults the previous behavior (the search list configured in the
  system's resolver configuration is used for relative names)
- defaults lifetime to 15sec (determines the number of seconds
  to spend trying to get an answer to the question)

Currently ca-del disables the target CA before deleting it.
Conceptually, this involves two separate permissions: modify and
delete.  A user with delete permission does not necessarily have
modify permission.

As we head toward enforcing IPA permissions in Dogtag, it is
necessary to decouple disablement from deletion, otherwise the
disable operation shall fail if the user does not have modify
permission.  Although it introduces an additional step for
administrators, the process is consistent, required permissions map
1:1 to the operations, and the error messages make it clear what
needs to happen (i.e. disable first).

before checking that all IP addresses in the CSR are reachable from

that it corresponds to the FQDN of a known host/service principal
(including principal aliases).  When a DNS name maps to a
"alternative" principal (i.e.  not the one given via the 'principal'
argument), this check was not being performed correctly.
Specifically, we were looking for the 'krbprincipalname' field on
the RPC response object directly, instead of its 'result' field.

To resolve the issue, dereference the RPC response to its 'result'
field before invoking the '_dns_name_matches_principal' subroutine.

4911a3f055 Prevent local account takeover
It was found that if an account was created with a name corresponding to
an account local to a system, such as 'root', was created via IPA, such
account could access any enrolled machine with that account, and the local
system privileges. This also bypass the absence of explicit HBAC rules.

root principal alias
-------------------

The principal "root@REALM" is now a Kerberos principal alias for
"admin". This prevent user with "User Administrator" role or
"System: Add User" privilege to create an account with "root" principal
name.

Modified user permissions
-------------------------

Several user permissions no longer apply to admin users and filter on
posixaccount object class. This prevents user managers from modifying admin
acounts.

- System: Manage User Certificates
- System: Manage User Principals
- System: Manage User SSH Public Keys
- System: Modify Users
- System: Remove Users
- System: Unlock user

``System: Unlock User`` is restricted because the permission also allow a
user manager to lock an admin account. ``System: Modify Users`` is restricted
to prevent user managers from changing login shell or notification channels
(mail, mobile) of admin accounts.

New user permission
-------------------

- System: Change Admin User password

The new permission allows manipulation of admin user password fields. By
default only the ``PassSync Service`` privilege is allowed to modify
admin user password fields.

Modified group permissions
--------------------------

Group permissions are now restricted as well. Group admins can no longer
modify the admins group and are limited to groups with object class
``ipausergroup``.

- System: Modify Groups
- System: Remove Groups

The permission ``System: Modify Group Membership`` was already limited.

Notes
-----

Admin users are mostly unaffected by the new restrictions, except for
the fact that admins can no longer change krbPrincipalAlias of another
admin or manipulate password fields directly. Commands like ``ipa passwd
otheradmin`` still work, though. The ACI ``Admin can manage any entry``
allows admins to modify other entries and most attributes.

Managed permissions don't install ``obj.permission_filter_objectclasses``
when ``ipapermtargetfilter`` is set. Group and user objects now have a
``permission_filter_objectclasses_string`` attribute that is used
by new target filters.

Misc changes
------------

Also add new exception AlreadyContainsValueError. BaseLDAPAddAttribute
was raising a generic base class for LDAP execution errors.

bee4204039 Support adding user ID overrides as group and role members
Second part of adding support to manage IPA as a user from a trusted
Active Directory forest.

Treat user ID overrides as members of groups and roles.

For example, adding an Active Directory user ID override as a member of
'admins' group would make it equivalent to built-in FreeIPA 'admin'
user.

We already support self-service operations by Active Directory users if
their user ID override does exist. When Active Directory user
authenticates with GSSAPI against the FreeIPA LDAP server, its Kerberos
principal is automatically mapped to the user's ID override in the
Default Trust View. LDAP server's access control plugin uses membership
information of the corresponding LDAP entry to decide how access can be
allowed.

With the change, users from trusted Active Directory forests can
manage FreeIPA resources if the groups are part of appropriate roles or
their ID overrides are members of the roles themselves.

973e0c04e4 idviews: handle unqualified ID override lookups from Web UI
First part of the required changes to merge a plugin to manage IPA as
a trusted Active Directory user.

It is not possible to omit ID view in IPA API but a client might specify
empty ID view. Up right now the empty view was considered an error. This
prevented Web UI from resolving ID overrides in a group member adder
dialog.

Default to 'Default Trust View' if the ID view is None or empty string
(''). Do this only for user ID overrides, as we do not support adding
group ID overrides as group members in a plugin to manage IPA as a
trusted Active Directory user[1].

Being a group member means an object in LDAP must have an object class
that allows 'memberOf' attribute because 389-ds 'memberof' plugin will
attempt to link back to the object from the group. Allow use of
'nsMemberOf' object class in ID overrides.

ecc0a96d16 support using trust-related operations in the server console
When using `ipa -e in_server=True console` on IPA master, the whole IPA
framework is loaded in the same process ('ipa console'). The context
defined for this configuration is 'cli'. Some trust-related operations
need to load Samba bindings and guard itself to 'lite' and 'server'
contexts.

Upon reviewing these cases I came to conclusion that these guards are
unnecessary. It is enough to require that the context is in the server
code.

Allow these operations if we are operating in server mode. This allows
to debug trust-related issued directly in the IPA console on IPA trust
controllers.

LDAP attribute options aren't enforced in the schema, thus we strip them
when checking attribute conformance with the schema. This, however, can
leave us with a situation when multiple base LDAP attribute names are

Use set of attribute names to deduplicate the list.

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.
