extdom plugin handles external operation over which SSSD asks IPA server about
trusted domain users not found through normal paths but detected to belong
to the trusted domains associated with IPA realm.
SSSD expects that user or group name in the response will be unqualified
because domain name for the user or group is also included in the response.
Strip domain name from the name if getgrnam_r/getpwnam_r calls returned fully
qualified name which includes the domain name we are asked to handle.
The code already expects that fully-qualified names are following user@domain
convention so we are simply tracking whether '@' symbol is present and is followed
by the domain name.
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.
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.

Request with a SID as input parameter do not contain the domain name,
hence is must be tried to resolve the SID first before the corresponding
domain can be looked up.

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.
Tests included

Any of the following checks:
- overlap between primary RID range and secondary RID range
- overlap between secondary RID range and secondary RID range
is performed now only if both of the ranges involved are local
domain ranges.

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.

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

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.
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.
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.
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.
