## managing TLS certificates ## managing TLS serts
When `ne_enable_ssl` is enabled, the certificates for the ca (root if standalone or intermediate), the nagios server and the key for the nagios server have to be provided through the following values:
- `ne_ssl_ca_cert_pem`
- `ne_ssl_cert_pem`
- `ne_ssl_privatekey_pem`
via Hiera (if you use it) or ENC. At the ENC need to add confdroid_nrpe::params and set those values.
If you don't need TLS encryption, leave `ne_enable_ssl` to the default value of `false`.

## Known Problems ## Known Problems
- SSL/TLS support: Version 3 of NRPE supposedly has support for SSL/ TLs. However, at the time of writing this module, this seems to be buggy, as I was unable to start the NRPE service as soon as the `ssl_cert_file` line was uncommented in the configuration file, despite having valid certs in the right position on the node. This happened when installing manually, not through this Puppet module. For that reason I included the `$ne_enable_ssl` boolean parameter, which is set to `false` by default, hence disabling SSL/TLS options until this has been fixed upstream, or a valid workaround has been found. Setting this option to `true` will include all SSL / TLS settings.
## Troubleshooting ## Troubleshooting
- `CHECK_NRPE: Unable to read output`: Nagios sudo access also needs Selinux to allow this. Default settings in this module take care for both through `$ne_allow_sudo` and `$ne_include_selinux`. - `CHECK_NRPE: Unable to read output`: Nagios sudo access also needs Selinux to allow this.
