Before this patch users could log in using only the OTP value. This
arose because ipapwd_authentication() successfully determined that
an empty password was invalid, but 389 itself would see this as an
anonymous bind. An anonymous bind would never even get this far in
this code, so we simply deny requests with empty passwords.
This patch resolves CVE-2014-7828.

This plugin ensures that all counter/watermark operations are atomic
and never decrement. Also, deletion is not permitted.
Because this plugin also ensures internal operations behave properly,
this also gives ipa-pwd-extop the appropriate behavior for OTP
authentication.

Currently the extdom plugin is basically used to translate SIDs of AD
users and groups to names and POSIX IDs.
With this patch a new version is added which will return the full member
list for groups and the full list of group memberships for a user.
Additionally the gecos field, the home directory and the login shell of a
user are returned and an optional list of key-value pairs which
currently will contain the SID of the requested object if available.

This prevents the reuse of TOTP tokens by recording the last token
interval that was used. This will be replicated as normal. However,
this patch does not increase the number of writes to the database
in the standard authentication case. This is because it also
eliminates an unnecessary write during authentication. Hence, this
patch should be write-load neutral with the existing code.
Further performance enhancement is desired, but is outside the
scope of this patch.

A mixture of implicit and explicit tagging was being used and this caused
a bug in retrieving the enctype number due to the way ber_scanf() loosely
treat sequences and explicit tagging.
The ASN.1 notation used to describe the getkeytab operation uses implicit
tagging, so by changing the code we simply follow to the specified encoding.

This new extended operation allow to create new keys or retrieve
existing ones. The new set of keys is returned as a ASN.1 structure
similar to the one that is passed in by the 'set keytab' extended
operation.
Access to the operation is regulated through a new special ACI that
allows 'retrieval' only if the user has access to an attribute named
ipaProtectedOperation postfixed by the subtypes 'read_keys' and
'write_keys' to distinguish between creation and retrieval operation.
For example for allowing retrieval by a specific user the following ACI
is set on cn=accounts:
(targetattr="ipaProtectedOperation;read_keys") ...
... userattr=ipaAllowedToPerform;read_keys#USERDN)
This ACI matches only if the service object hosts a new attribute named
ipaAllowedToPerform that holds the DN of the user attempting the
operation.

The patch makes sure the following rules are implemented:
* No ID range pair can overlap on base ranges, with exception
of two ipa-ad-trust-posix ranges belonging to the same forest
* For any ID range pair of ranges belonging to the same domain:
* Both ID ranges must be of the same type
* For ranges of ipa-ad-trust type or ipa-local type:
* Primary RID ranges can not overlap
* For ranges of ipa-local type:
* Primary and secondary RID ranges can not overlap
* Secondary RID ranges cannot overlap
For the implementation part, the plugin was extended with a domain ID
to forest root domain ID mapping derivation capabilities.
