Post-installation steps for ubuntu/debian

After you install oidentd on your Ubuntu/Debian system, continue with the following steps:

Verify that the Ident server accepts IPv6 connections to prevent authentication failure. To do so, you must enable this capability. In the script /etc/init.d/oidentd, change the line from:
```
exec="/usr/sbin/oidentd"
```
to
```
exec="/usr/sbin/oidentd -a ::"
```
Then, at the Linux prompt, start oidentd with -a ::.
Restart the server with the following command:
```
$ /etc/init.d/oidentd restart
```

Post-installation steps for red hat 7.x/CentOS 7.x and SUSE Linux enterprise server

After you install the required packages on your Red Hat 7.x/CentOS 7.x or SUSE Linux Enterprise Server system, continue with the following steps:

Enable the auth service by setting disable = no in the configuration file /etc/xinetd.d/auth. If this file does not exist, create it. The following is a sample configuration file:

service auth
{
        disable = no
        socket_type = stream
        wait = no
        user = ident
        cps = 4096 10
        instances = UNLIMITED
        server = /usr/sbin/in.authd
        server_args = -t60 --xerror --os
}

Restart the xinetd service with the following command:
```
$ service xinetd restart
```
