libnss-ato (Name Service Switch module All-To-One)
==========
The libnss_ato module is a set of C library extensions which allows to map every nss request for unknown user to a single predefined user.
Description
=========
Suppose your system has only one account (apart from root and system users) named user_test:
```console
]$ id user_test
]$ uid=1000(user_test) gid=1000 groups=1000
```
If you add libnss-ato to the chain of nss modules (in /etc/nsswitch.conf) you get something like:
```console
]$ id randomname
]$ uid=1000(user_test) gid=1000 groups=1000
```
for every query of a random username not present in /etc/passwd.
Why?
=========
This module can be used for pubblic workstations where you only need to verify username / password from a pam module (for example pam-krb5 for Active Directory users) and there is no need to give the user his own uid, gid or homedir.
Installation from source
=========
From source just make and make install.
The only configuration file is `/etc/libnss-ato.conf` which consists of one line in the passwd format. For example:
```console
test_user:x:1000:1000:Test User:/home/test:/bin/bash
```
Only the first line of the file `/etc/libnss-ato.conf` is parsed and the
uid number (1000 in this example) must be the one of a real user in the system.
Here an example of the system file `/etc/nsswitch.conf` to make use of libnss-ato:
```console
passwd: files ato
group: files
shadow: files ato
```
If you have an nscd service running, please reload it after the changes in the file
`/etc/nsswitch.conf`.
Installation from Debian packages
=========
To build the Debian packages, run the following:
```console
fakeroot debian/rules binary
```
This should create the correct `.deb` in the parent directory.
This package can then be installed as with any other package:
```console
sudo dpkg -i
```
You will then need to modify the config files, as above.
Installation from CentOS packages
=========
To build the CentOS packages, run the following:
```console
make rpm
```
This should create the correct `.rpm` in the parent directory.
This package can then be installed as with any other package:
```console
sudo yum install
```
You will then need to modify the config files, as above.
