A way of expressing nsswitch.conf configurations declaratively. This
should manage the standard 15 databases NSS supports, plus the sudo
entry
respected by sudo since the 1.7.0 release.
The 2.x series of this module officially adopts the Puppet 4 parser syntax and
other new Puppet features. The 2.x series will no longer work with Puppet 3 or
earlier. One benefit is the removal of dependency the trlinkin-validate_multi
module.
Currently this module has support for EL based Linux distributions, Fedora, Debian/Ubuntu, and Gentoo. This module by default will create a basic nsswitch.conf that uses defaults derived from what the distribution uses in the nsswitch.conf file on fresh install. These defaults have been verified on the mentioned distributions by the kindness and diligence of contributors, of which I'm very grateful.
This module should be capable of supporting the following systems using
Puppet versions 4 and 5 with the ruby versions that are released with
the AIO (all in one installer). For an exact matrix see .travis.yml
.
- Debian/Ubuntu 10.04, 12.04
- Solaris 10, 11, 11.1, 11.2, 11.3
- Variants of Enterprise Linux 6 and 7 (Such as Amazon Linux, Scientific Linux, etc)
- Fedora (defaults need validation)
- Gentoo
- FreeBSD 10.3, 10.4, 11.1
- LinuxMint 17.2
- SLES 11, 12
Testing has only confirmed functionality on the following:
- Ubuntu 12.4
- Fedora 19
- Centos 6/7
- RHEL 6/7
See REFERENCE.md for full API details.
This is the class by which you will manage the nsswitch.conf file. There is one parameter per standard database NSS supports. The class accepts both strings and arrays as parameters. The benefit being, you could possibly merge an array of options with hiera. When using an array, each element should be the lookup service followed by the reaction statement.
Available parameters are:
- passwd
- group
- shadow
- hosts
- bootparams
- aliases
- automount
- ethers
- netgroup
- netmasks
- network
- protocols
- publickey
- rpc
- services
- shells
- sudo
For more information on NSS, please see the man pages. man 5 nsswitch.conf
