If you are going to experiment with the views, then please note that
unfortunately some bugs slipped into the 7.1 release. If you encounter
problems, please either try installing latest packages for SSSD and IPA,
make sure SSSD is updated also on the server side.

Some SSSD bugs are not planned for patching until 7.2, in that case you
might need to install upstream packages such as:
    https://copr.fedoraproject.org/coprs/lslebodn/sssd-1-12/

Some of the bugs are:
