With the new ipa_server_mode SSSD is able to read user and group data
from trusted AD domains directly and makes this data available via the
NSS responder. With this mode enabled winbind is not needed anymore to
lookup users and groups of trusted domains.
This patch removed the calls to winbind from the extdom plugin and
replaces them with standard POSIX calls like getpwnam() and calls from
libsss_nss_idmap to lookup SIDs.
Fixes https://fedorahosted.org/freeipa/ticket/3637 because now the
extdom plugin does not need to handle idranges anymore, but everything
is done inside SSSD.
For a proper SASL bind with GSSAPI against an AD LDAP server a PAC is
needed. To allow SSSD in ipa_server_mode to access the LDAP or GC server
of a trusted domain with the credentials of a FreeIPA server host a
PAC must be added to the TGT for the host.
We use the well know RID of the Domain Computers group (515) for the
primary gid element of the PAC, this is the same as AD uses for host
tickets. The rid element of the PAC is set to the well know RID of the
Domain Controllers group (516). This is working for the SSSD use case
but might be improved later for more general use cases.
To determine if a host is a FreeIPA server or not it is checked if there
is an entry for the host in cn=master,cn=ipa,cn=etc,$base. Unfortunately
this requires an additional LDAP lookup. But since TGS-REQs for hosts
should be rare I think it is acceptable for the time being.

This was to resolve a -Werror=format-security error.
ipa_extdom_extop.c: In function 'ipa_extdom_extop':
ipa_extdom_extop.c:144:9: error: format not a string literal and no format
arguments [-Werror=format-security]
Windows DCs return an empty reply when a legal request cannot satisfied.
If we get EINVAL or ENOENT it means the information requested could not be
found or input parameters were bogus.
Always return an empty reply in these cases.
On any other internal error just return, the request may have been legit but we
can't really handle it right now, pretend we never saw it and hope the next
attempt will succeed.

1. Stop using getdomainname() as it is often not properly initialized
2. The code using getdomainname() was not working anyway it was trying to
look at the function call output in hostname which is always empty at that
point.
3. Always check the requested domain matches our own, we cannot reply to
anything else anyway.

This daemon listens for RADIUS packets on a well known
UNIX domain socket. When a packet is received, it queries
LDAP to see if the user is configured for RADIUS authentication.
If so, then the packet is forwarded to the 3rd party RADIUS server.
Otherwise, a bind is attempted against the LDAP server.

If OTP is enabled for a user, then:
1. Long-term keys are not provided to KDB
2. The user string 'otp' is defined to KDB
Since it is not secure to send radius configuration information
over krb5 user strings, we simply set the string to a known default
('[]') which enables the default configuration in the KDC.

PASSDB API in Samba adds support for specifying UPN suffixes. The change
in ipasam will allow to pass through list of realm domains as UPN suffixes
so that Active Directory domain controller will be able to recognize
non-primary UPN suffixes as belonging to IPA and properly find our KDC
for cross-realm TGT.
Since Samba already returns primary DNS domain separately, filter it out
from list of UPN suffixes.
Also enclose provider of UPN suffixes into #ifdef to support both
Samba with and without pdb_enum_upn_suffixes().

cmocka is a more advanced unit test framework for C-code than the
currently used check framework. This patch adds configure checks and
makefile variables so that new unit tests can use cmocka.

The plugin is configured unconditionally (i.e. does not check if
IPA was configured with DNS) as the plugin is needed on all
replicas to prevent objectclass violations due to missing SOA
serial in idnsZone objectclass. The violation could happen if just
one replica configured DNS and added a new zone.

There were several problems:
- A cut-n-paste error where the wrong value was being considered when
an account was administratively unlocked.
- An off-by-one error where LDAP got one extra bind attempt.
- krbPwdPolicyReference wasn't being retrieved as a virtual attribute so
only the global_policy was used.
- The lockout duration wasn't examined in the context of too many failed
logins so wasn't being applied properly.
- Lockout duration wasn't used properly so a user was effectively unlocked
when the failure interval expired.
- krbLastFailedAuth and krbLoginFailedCount are no longer updated past
max failures.

The way how unhashed password is stored in the entry was changed in
389-ds-base-1.3.0, it is now stored in an entry extension rather than
in a magic attribute unhashed#user#password. New API using an entry
extension was introduced. ipa-pwd-extop should take advantage of the
new API as the old one will be removed in 389-ds-base-1.3.1.

Change user-add's uid & gid parameters from autofill to optional.
Change the DNA magic value to -1.
For old clients, which will still send 999 when they want DNA
assignment, translate the 999 to -1. This is done via a new
capability, optional_uid_params.

Since we use associatedDomain attribute to store information about UPN suffixes
and our own domain, searching subtree is going to return more than one entry.
Limit search for own domain by base scope as we only need to fetch our own

Currently kdb5kdc crashes on exit if the ipadb KDB modules is loaded and trusts
are configured. The reason is the talloc autofree context which get initialised
during the ndr_push_union_blob() call. On exit the KDC module is unloaded an
later on atexit() tries to free the context, but all related symbols are
already unloaded with the module.
This patch frees the talloc autofree context during the cleanup routine of the
module. Since this is called only at exit and not during normal operations this
is safe even if other KDC plugins use the talloc autofree context, e.g. via
some Samba libraries, as well.

SIDs in incoming MS-PAC were checked and filtered with a fixed list of
well-known SIDs. Allow reading the SID blacklist from LDAP
(ipaNTSIDBlacklistIncoming and ipaNTSIDBlacklistOutgoing) and add the list
to mspac adtrust structure. Use the hardcoded SID list only if the LDAP
SID list is not configured.
LIMITATION: SID blacklist list is not used yet.

ipa-kdb did not reinitialize trusted domain configuration when it
was loaded to ipa-kdb. However, admin then would have to restart
krb5kdc if he wanted to apply the change to running krb5kdc service.
Run ipadb_reinit_mspac unconditionally every time when trusted domain
is loaded. Among the already configured 1 minute grace time, also
add a quick check if there is at least one configured trusted domain
before reinitializing the mspac structure.

When all SIDs in info3.sids structure were filtered out, we tried
to talloc_realloc to zero memory size. talloc_realloc then returned
NULL pointer and filter_login_info returned with ENOMEM.
The code now rather frees the SID array and set info3.sidcount to
correct value.
Since in Kerberos V5 are used 32-bit unix timestamps, setting
maxlife in pwpolicy to values such as 9999 days would cause
integer overflow in krbPasswordExpiration attribute.
This would result into unpredictable behaviour such as users
not being able to log in after password expiration if password
policy was changed (#3114) or new users not being able to log
in at all (#3312).
The timestamp value is truncated to Jan 1, 2038 in ipa-kdc driver.
