sssd_ad

This cookbook installs SSSD on a Ubuntu system and configures it for Active Directory authentication. It loosely follows the directions found here: https://help.ubuntu.com/lts/serverguide/sssd-ad.html.

IMPORTANT: This cookbook assumes the system's FQDN (e.g. 'server.example.contoso.com') is in /etc/hosts. Joining the domain may fail if this is not the case. See the above link for details.

Platforms

Tested on Ubuntu 14.04.

Attributes

• ['sssd_ad']['access_filter'] - optional ad_access_filter for the joined domain, e.g. "(&(sAMAccountName=jo*)(unixHomeDirectory=*))"
• ['sssd_ad']['cache_credentials'] - boolean to enable SSSD credential caching; defaults to false
• ['sssd_ad']['dc'] - the FQDN of the primary domain controller
• ['sssd_ad']['use_ntp'] - configure NTP to sync with the primary domain controller; defaults to true
• ['sssd_ad']['join_domain'] - join the system to the domain (requires credentials in a chef-vault item); defaults to false
• ['sssd_ad']['vault_name'] - name of the data bag containing domain credentials
• ['sssd_ad']['vault_item'] - name of the chef-vault item containing domain credentials

Usage

Add the sssd_ad::default recipe to the node's run list, and set the ['samba']['workgroup'], ['samba']['options']['realm'], and ['sssd_ad']['dc'] attributes. If the system should be joined to the domain automatically, set the join_domain attribute to true and create a chef-vault item containing AD credentials that have appropriate permissions.
