[SSSD] [PATCH] Add a new option ad_access_filter

[Jakub Hrozek]

Hi,

the attached patches implement the new option ad_access_control as
designed in
https://fedorahosted.org/sssd/wiki/DesignDocs/ActiveDirectoryAccessControl

The only part not implemented exactly as per the design page is changing
the default. I will write an e-mail about the issue into the thread with
the design decision so that also people who filter out patches can
participate.
