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.
https://fedorahosted.org/freeipa/ticket/3347
Default value "1" is added to replicated idnsZone objects
if idnsSOASerial attribute is missing.

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- krbLastFailedAuth and krbLoginFailedCount are no longer updated past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.

Instead of always adding a PAC to the Kerberos ticket the global default
for the authorization data and the authorization data of the service
entry is evaluated and the PAC is added accordingly.

The ipaKrbAuthzData LDAP attribute is read together with the other data
of the requestedprincipal and the read value(s) are stored in the e-data

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
domain information here, not UPN suffixes.

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.

This function retried an LDAP search when the result was OK due to
flawed logic of retry detection (ipadb_need_retry function which
returns true when we need retry and not 0).

All known memory leaks caused by unfreed allocated memory or unfreed
LDAP results (which should be also done after unsuccessful searches)

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.

SIDs in case they belong to our domain.

Wrap the password change extop in a transaction.
Fix the case where a password is reset and then immediately used. If done
fast enough then the KDC may not detect that the password is expired and
grant access using the expired password rather than prompting for a reset.

Ther3 are two global ipaConfig options to disable undesirable writes that
have performance impact.
The "KDC:Disable Last Success" will disable writing back to ldap the last
successful AS Request time (successful kinit)
The "KDC:Disable Lockout" will disable completely writing back lockout
related data. This means lockout policies will stop working.

Currently only the group SIDs from a PAC are used to find out about the
membership in local groups. This patch adds the user SID to the list.
Fixes https://fedorahosted.org/freeipa/ticket/3257
The current Linux NFS server is severely limited when it comes to handling
kerberos tickets. Bsically any ticket bigger than 2k will cause it to fail
authentication due to kernel->userspace upcall interface restrictions.
Until we have additional support in IPA to indivdually mark principals to
opt out of getting PACs attached we always prevent PACs from being attached
to TGTs or Tickets where NFS is involved.
Commands ipa idrange-add / idrange-mod no longer allows the user
to enter primary or secondary rid range such that has non-zero
intersection with primary or secondary rid range of another
existing id range, as this could cause collision.
Unit tests added to test_range_plugin.py

Currently the data about trusted domains is read once at startup. If a
new trust is added the KDC must be restarted to know about the new
trust. This patch reloads the trust data if there is a request from an
unknown domain. To make DOS attacks a bit harder the data can be updated
only once in a minute.

If match_entry == NULL all principals should be iterated.

With this change ipasam is able to ask for ipaNTHash generation and if
corresponding Kerberos key is available, will be able to retrieve generated ipaNTHash.

When developing and testing in the same environment, multiple re-installs
may be needed. This means previously issued and cached Kerberos credentials
will become invalid upon new install.
ipasam passdb module for Samba uses Kerberos authentication when talking to
IPA LDAP server. Obtained Kerberos credentials are cached during their lifetime.
However, the ccache is not removed automatically and if IPA setup is made
again, cached credentials are used, only to discover that they are invalid.
With this change invalid correctly obtained cached credentials are recognized
and, if LDAP SASL bind fails, new credentials are requested from the KDC.

This check the PAC we receive is consistent.

Ticket #2849
The function filter_pac was not filtering the pac at all, it was merely
augmenting it with additional data relevant to the IPA server.
Change the name of the function to avoid confusion.
While there I also simplified and cleaed up the code a bit with regard to
variable names and usage.
The NT Hash is the same thing as the RC4-HMAC key, so we add a function to
extract it from krb5 keys if they are available to avoid forcing a password
change when configuring trust relationships.
This moves the decoding function that reads the keys from the ber format
into a structure in the common krb5 util code right below the function
that encodes the same data structure into a ber format.
This way the 2 functions are in the same place and can be both used by
all ia components.
The DNA magic value can be arbitrarily changed by admins so we cannot use a
const value to check. And we relly do not need to check at all. If the DNA
plugin is broken and leaves magic values to reach the post-op stage we have
bigger problems. So just simply get rid of this check.
With c43505b621725c9a754f0ee98318d451b093f2ed in samba git master
the function sid_check_is_domain() was renamed to sid_check_is_our_sam().

SASL bind callback due to refactoring was referencing local variable which
didn't exist all the time. Fix that by including a copy of service principals
into ipasam long term private struct.
Rework ccache handling to avoid re-initing every time callback is called
This extop can be used by clients of the IPA domain, e.g. sssd, to
retrieve data from trusted external domains. It can be used e.g. to map
Windows SIDs to user or groups names and back.
If one or more of the external groups given in the PAC can be found in
the ipaExternalGroup objects and these objects are members of local
groups, the SIDs of the local groups are added to the PAC.
A postop plugin is added to create the SID for new created users and
groups. A directory server task allows to set the SID for existing
users and groups.
