Fixed. cacertdir_rehash script is also downloaded if necessary.

Fixed. We agreed it is best to specify the defaults explicitly in config files,
while including a comment about a possible need for manual modification of the
script.

Subject: [PATCH] Add ipa-advise plugins for legacy clients
Old versions of SSSD do not directly support cross-realm trusts between IPA
and AD. This patch introduces plugins for the ipa-advise tool, which should
help with configuring an old version of SSSD (1.5-1.8) to gain access to
resources in trusted domain.
Since the configuration steps differ depending on whether the platform includes
the authconfig tool, two plugins are needed:
* config-redhat-sssd-before-1-9 - provides configuration for Red Hat based
systems, as these system include the autconfig utility
* config-generic-sssd-before-1-9 - provides configuration for other platforms

Add a new API command 'compat-is-enabled' which can be used to determine
whether Schema Compatibility plugin is configured to serve trusted domain
users and groups. The new command is not visible in IPA CLI.
