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.

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.

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.

"Kerberos principal expiration" is set in UTC and when server is in
different timezone, the time difference between timezone is respected by
the IPA server/client for Kerberos authentication.
The problem is due to mktime() assuming default time zone but since we
parse the time using Zulu (UTC+0) timezone, mktime() forces current time
zone offset added.
The method is using mktime() and comparing to the current time obtained
with time(NULL). According to its man page, mktime is considering the
time as local time:
The mktime() function converts a broken-down time structure, expressed
as local time, to calendar time representation.
Instead mktime() we should use timegm(). The problem is that it is
non-standard GNU extension and it is recommended (in the man page for
timegm(3)) to avoid its use. An alternative is to set TZ=UTC, call
mktime(), unset TZ, but since we are running in a multi-threaded
environment this is problematic.
On the other hand, we already rely on GNU extensions and enable them
with -D_DEFAULT_SOURCE=1, so use of timegm() is enabled already.
The fix, therefore, is to use timegm() instead of mktime() in
daemons/ipa-slapi-plugins/ipa-pwd-extop/prepost.c in two places where we
first do 'strptime()' with Zulu time zone (in ipapwd_pre_bind() and
ipapwd_write_krb_keys()).

An enterprise principal is typically "name@SOMEREALM@REALM", but any

re-parse it again with default realm values, to get our realm

Previously, FreeIPA only allowed to issue PAC record in a ticket
for the following principal types:
- for IPA users
- for a host principal of one of IPA masters
- for a cifs/ or HTTP/ service on one of IPA masters
To allow S4U2Self operations over trust to AD, an impersonating service
must have PAC record in its TGT to be able to ask AD DCs for a S4U2Self
ticket. It means any IPA service performing S4U2Self would need to have
PAC record and the constraints above prevent it from doing so.
However, depending on whether the service or host principal belongs to
one of IPA masters, we need to set proper primary RID to 516 (domain
controllers) or 515 (domain computers).

S4U extensions. We have to verify/sign PAC and take the realm into

The use of extended functions require krb5 1.17+.
For PAC verification, we have to filter existing PAC CLIENT-INFO
structure in cross-realm S4U case because otherwise old CLIENT-INFO
would change the PAC principal due to adding or ommiting the realm in
transition. Since a new PAC CLIENT-INFO will be provided by
k5_insert_client_info() anyway, we can filter it in all cases.
Generate PAC only for the first S4U2Self request to the client realm
(client != NULL). Otherwise, use the PAC from the cross-realm ticket.
The latter PAC belongs to the impersonated user.
Foreign (inner) principal look up in non-AS request returns
KRB5_KDB_NOENTRY.
Finally, in PAC signing we have to take the realm into account as well
for S4U2Self cross-realm operation. This does not work when compiling
against krb5 1.17 at the moment because sign_authdata() callback does
not know whether we are dealing with an issuing referral or not. In 1.18

Helper utility to investigate PAC content of users in trusted

transition.
1. Direct ticket acquisition
In direct ticket acquisition mode the utility first does one of the
following actions:
- obtain a TGT ticket for a user principal using supplied password
- import existing TGT from a default credentials cache
Once a user TGT is available, the utility will attempt to acquire a service
ticket to a service which key is specified in a keytab (default or
passed with --keytab option) and simulate establishing context to the
service application.
If establishing context succeeds, MS-PAC content of the service ticket
will be printed out.
2. S4U2Self protocol transition
In protocol transition case a service application obtains own TGT using
a key from the keytab and then requests a service ticket to itself in
the name of the user principal, performing S4U2Self request.
If accepting this service ticket succeeds, MS-PAC content of the service
ticket will be printed out.
If KDC does not support or rejects issuing MS-PAC record for a user, an
error message 'KDC has no support for padata type' will be printed.
