Description

This module manages YP/NIS.

This module can configure the YP/NIS domain, manage the ypbind daemon to bind a client to a YP server and create and maintain master & slave YP servers using ypserv and associated daemons. It can also in the special case of OpenBSD manage the ypldap daemon to fetch YP maps from LDAP.

Setup

What yp affects

On OpenBSD this module will add the traditional +::... entries to the bottom of the /etc/passwd and /etc/group files.

Setup Requirements

You will need to manage the RPC portmapper by using bodgit/portmap or by other means.

On Linux you will need to adjust the /etc/nsswitch.conf file and PAM configuration yourself. Both trlinkin/nsswitch and herculesteam/augeasproviders_pam are known to work and used in the examples and tests in this module.

Beginning with yp

Bind a client to a YP domain using three YP servers:

include ::portmap

class { '::yp':
  domain => 'example.com',
}

class { '::yp::bind':
  domain  => 'example.com',
  servers => ['192.0.2.1', '192.0.2.2', '192.0.2.3'],
}

Class['::portmap'] ~> Class['::yp::bind'] <~ Class['::yp']

if $::osfamily == 'RedHat' {
  class { '::nsswitch':
    passwd    => ['files', 'nis', 'sss'],
    shadow    => ['files', 'nis', 'sss'],
    group     => ['files', 'nis', 'sss'],
    hosts     => ['files', 'nis', 'dns'],
    netgroup  => ['files', 'nis', 'sss'],
    automount => ['files', 'nis'],
    require   => Class['::yp::bind'],
  }

  pam { 'nis':
    ensure    => present,
    service   => 'system-auth-ac',
    type      => 'password',
    control   => 'sufficient',
    module    => 'pam_unix.so',
    arguments => [
      'md5',
      'shadow',
      'nis',
      'nullok',
      'try_first_pass',
      'use_authtok',
    ],
    require   => Class['::yp::bind'],
  }
}

Usage

Create a standalone YP server:

include ::portmap

class { '::yp':
  domain => 'example.com',
}

class { '::yp::serv':
  domain => 'example.com',
}

Class['::portmap'] ~> Class['::yp::serv'] <- Class['::yp']

Create a master YP server with two additional slaves:

include ::portmap

class { '::yp':
  domain => 'example.com',
}

class { '::yp::serv':
  domain => 'example.com',
  maps   => [
    'passwd.byname',
    'passwd.byuid',
    'group.bygid',
    'group.byname',
    'netid.byname',
  ],
  slaves => [
    '192.0.2.2',
    '192.0.2.3',
  ],
}

Class['::portmap'] ~> Class['::yp::serv'] <- Class['::yp']

Create a slave YP server pointing at the above master YP server:

include ::portmap

class { '::yp':
  domain => 'example.com',
}

class { '::yp::serv':
  domain => 'example.com',
  maps   => [
    'passwd.byname',
    'passwd.byuid',
    'group.bygid',
    'group.byname',
    'netid.byname',
  ],
  master => '192.0.2.1',
}

class { '::yp::bind':
  domain => 'example.com',
}

Class['::portmap'] ~> Class['::yp::serv'] <- Class['::yp']
Class['::yp::serv'] -> Class['::yp::bind'] <~ Class['::yp']

For OpenBSD only, set up ypldap to create YP maps from an LDAP server and also bind to it. This is the equivalent to PAM/LDAP on Linux:

include ::portmap

class { '::yp::ldap':
  domain      => 'example.com',
  directories => {
    'dc=example,dc=com' => {
      bind_dn => 'cn=ypldap,dc=example,dc=com',
      bind_pw => 'password',
      server  => '192.0.2.1',
    },
  },
}

class { '::yp':
  domain => 'example.com',
}

class { '::yp::bind':
  domain => 'example.com',
}

Class['::portmap'] ~> Class['::yp::ldap'] ~> Class['::yp::bind'] <~ Class['::yp']

Reference

The reference documentation is generated with puppet-strings and the latest version of the documentation is hosted at https://bodgit.github.io/puppet-yp/ and available also in the REFERENCE.md.

Limitations

This module was primarily written with deploying ypldap on OpenBSD in mind however to do that I realised I had classes for everything bar ypserv so I added that and made sure it was portable enough to work on one other OS. It works however I don't expect many people to still be using traditional YP/NIS.

This module has been built on and tested against Puppet 5 and higher.

The module has been tested on:

  • RedHat Enterprise Linux 6/7
  • OpenBSD 6.0/6.1/6.2/6.3

Development

The module relies on PDK and has both rspec-puppet and beaker-rspec tests. Run them with:

$ bundle exec rake spec
$ PUPPET_INSTALL_TYPE=agent PUPPET_INSTALL_VERSION=x.y.z bundle exec rake beaker:<nodeset>
