#### `freeradius::virtual_module`



Define a virtual module which consists of one or more other modules, for failover or

load-balancing purposes.



##### `name`

##### `submodules`

##### `type`



```puppet

freeradius::virtual_module { 'myldap':

  submodules => ['ldap1', 'ldap2'],

  type       => 'redundant-load-balance',

}

```

yields

```

redundant-load-balance myldap {

	ldap1

	ldap2

}

```



## Limitations



This module is targeted at FreeRADIUS 3.x running on CentOS 7. It will not work on

manifests/virtual_module.pp
