This cookbook installs SSSD and configures it for LDAP authentication. As part of the setup of SSSD it will also remove the NSCD package as NSCD is known to interfere with SSSD (https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/usingnscd-sssd.html).

Arbitrary key/value pairs may be added to the ['sssd_conf'] attribute object. These key/values will be expanded in the domain block of sssd.conf. This allows you to set any SSSD configuration value you want, not just ones provided by the attributes in this cookbook.

If you manage your own CA then the easiest way to inject the certificate for system-wide use is as follows:
cp ca.crt /etc/pki/ca-trust/source/anchors
update-ca-trust enable
update-ca-trust extract
cp ca.crt /usr/local/share/ca-certificates
update-ca-certificates
