Some bits we used to help us deploy OpenLDAP.

• 002-syncrepl.rb [MIT] - The Syncrepl resource we made for updating syncrepl information using Chef.
• 003-helpers.rb [MIT] - Helpers used in communicating with LDAP.
• 004-ldapmodify.rb [MIT] - Another resource used for making quick changes to LDAP. Works like an exec block.

Important

To use this, you'll need to make sure the net-ldap chef gem is installed.

Sample use of the Chef resource

chef_gem 'net-ldap' do
  compile_time true
  version '0.15.0'
end

# ldap_pws should point to a databag with LDAP passwords
# ldaphosts should be an array of your LDAP hosts in role:ldap
syncreplrid = Hash[search(:node, 'role:ldap', :filter_result => { :name => ['name'], 'id' => ['openldap', 'serverid'] }).map { |k| [k['name'], k['id']] }]

ldaphosts.each do |e|
  syncrepl "sr-#{e['name']}" do
    server "#{node.name}.#{node.environment}.contoso.local"
    targetdb 'olcDatabase={1}mdb,cn=config'
    bindpw ldap_pws['configpw']
    rid syncreplrid[e['name']].to_s
    syncprovider "ldap://#{e['name']}.#{node.environment}.contoso.local"
    tls_cert '/etc/ldap/tls/replication.pem'
    tls_key '/etc/ldap/tls/replication-key.pem'
    tls_cacert '/etc/ssl/certs/tsldap.pem'
    searchbase base_dn
    not_if { node.name == e['name'] }
  end
end

if ldaphosts.count > 1
  ruby_block 'clean out old syncrepls' do
    block do
      hosts = remove_old_syncrepls(ldaphosts)
      hosts.each do |e|
        syncrepl "sr-#{e}" do
          action :remove
          server "#{node.name}.#{node.environment}.contoso.local"
          targetdb 'olcDatabase={1}mdb,cn=config'
          bindpw ldap_pws['configpw']
          syncprovider "ldap://#{e}.#{node.environment}.contoso.local"
          tls_cert '/etc/ldap/tls/replication.pem'
          tls_key '/etc/ldap/tls/replication-key.pem'
          tls_cacert '/etc/ssl/certs/tsldap.pem'
          searchbase base_dn
        end
      end
    end
  end
  ldapmodify 'enable mirrormode' do
    server "#{node.name}.#{node.environment}.contoso.local"
    basedn 'cn=config'
    targetdn 'olcDatabase={1}mdb,cn=config'
    binddn 'cn=admin,cn=config'
    bindpw ldap_pws['configpw']
    changes [[:add, :olcMirrorMode, 'TRUE']]
    notifies :create, 'ruby_block[openldap-setmirrormode-done]', :immediately
    not_if { node.attribute?('openldap-setmirrormode-done') }
  end

  ruby_block 'openldap-setmirrormode-done' do
    block do
      node.normal['openldap-setmirrormode-done'] = true
      node.save
    end
    action :nothing
  end
end
