Ansible Role: sssd-ldap

An Ansible Role that installs and configure sssd, nsswitch, pam and sshd to get user accounts from LDAP

Currently tested on

• Ubuntu 18.04.2 LTS (Bionic Beaver)

Requirements

You have to define some variables required to connect to LDAP server

Of course you can define credentials used to bind to your LDAP server in a plain text - but I strongly recommend using ansible Vault.

ldap_search_base: "cn=accounts,dc=example,dc=com"
ldap_user_search_base: "cn=users,cn=accounts,dc=example,dc=com"
ldap_group_search_base: "cn=groups,cn=accounts,dc=example,dc=com"
ldap_pam_filter: "&(objectclass=posixAccount)(!(nsaccountlock=True))"
ldap_bind_dn: !vault |
  $ANSIBLE_VAULT;1.1;AES256
  ( ... )
ldap_bind_pw: !vault |
  $ANSIBLE_VAULT;1.1;AES256
  ( ... )

Other role variables

You can find available options in defaults/main.yml and templates/sssd.conf.j2

Most important are

use_sssd: true   #  why would anyone want to change it?
sssd_use_ssh_keys_from_ldap: true
ldap_user_ssh_public_key: "ipaSshPubKey"

sshd_AuthorizedKeysCommand: /usr/bin/sss_ssh_authorizedkeys
sshd_AuthorizedKeysCommandUser: root

sssd_create_homedir: true
sssd_cache_credentials: true

Dependencies

None.
