RHEL7: sudoers and value "sss"

[anders-larsson]

Hello,

Pull request #37 introduced a bug with its default settings causing an error message every time a user runs the sudo command. This only occurs if the package sssd is not installed. The missing library seems to be present in sssd-common.

Since sssd is not always installed on RHEL7 systems I would propose to remove 'sss' for the default sudoers nsswitch configuration or make a test which only applies if the package sssd is present on the system.

sudo: Unable to dlopen /usr/lib64/libsss_sudo.so: (null)
sudo: Unable to initialize SSS source. Is SSSD installed on your machine?

Or instead of removing sss as standard add the package sssd-common as requirement. But one of them ^^
