IdM web UI enables smart card login
The Identity Management (IdM) web UI enables users to log in using smart cards. Note that this feature is experimental and not supported.
Description of problem:
IdM Web UI in RHEL-7.2 or older only allows Kerberos or Password authentication. The Web UI capabilities should be extended to also allow Smart Card authentication for environments leveraging Smart Card authentication instead of Kerberos.
This change means changing current Web UI authentication architecture, which does a kinit internally, when a password is passed. This cannot be done with the Smart Cards as Web UI does not have access to it.
As an Administrator in Government Sector (required to use Smart Cards), I want to authenticate to the IdM Web UI with my Smart Card, so that I am not forced to enable password authentication which is forbidden in my environment.
This feature was investigated and implemented as a POC for IdM in RHEL-7.3. Given current IdM Server architecture around it's Web (Apache) service, the solution cannot unfortunately be claimed as ready for production use due to security concerns and lack of privilege separation.
Therefore, the feature will be only presented as Experimental feature for users, where they can qualify it, test in their environment and report back if it works and satisfies the expectations/requirements. The feature won't be enabled by default and will require configuration (including API/CLI and Web UI plugins).

Current configuration procedure is being developed here:
Given above, I am changing the feature to "Experimental". A new Bugzilla will be created to track "proper" implementation that is secure and better suited for production use.
The page http://www.freeipa.org/page/V4/External_Authentication/Setup describes the status of the smart card / x509 certificate authentication in FreeIPA 4.4 and in the upcoming RHEL release. It relies on WebUI plugin and Apache HTTP Server configuration, available from external yum repository.
