sssd_ldap Cookbook

Build Status Cookbook Version

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).

Attributes

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.

Recipes

CA Certificates

If you manage your own CA then the easiest way to inject the certificate for system-wide use is as follows:

RHEL

cp ca.crt /etc/pki/ca-trust/source/anchors
update-ca-trust enable
update-ca-trust extract

Debian

cp ca.crt /usr/local/share/ca-certificates
update-ca-certificates
