# auth\_smb(8)

nnrpd Samba authenticator

## NAME

auth\_smb - nnrpd Samba authenticator

## SYNOPSIS

**auth\_smb** **server** \[**backup\_server**\] **domain**

## DESCRIPTION

This program does authentication for **nnrpd** against an SMB server.  It passes the received username and password to **server** for validation in the specified SMB **domain**.  A backup server may optionally be supplied; if it is missing, only **server** is used.

If authentication is successful, the original username is returned as the authentication identity.  Brief errors, including incorrect password and failure contacting the server, are logged.

## EXAMPLE

The following [*readers.conf*(5)](/readers.conf/5.md) fragment grants access to users who can authenticate against an SMB server:

```
    auth windows {
        auth: "auth_smb pdc.example.com bdc.example.com USERS"
        default-domain: "users.example.com"
    }
```

```
    access internal {
        users: "*@users.example.com"
        newsgroups: example.*
    }
```

Access is granted to the example.\* groups after successful authentication.

## BUGS

We should link against an external SMB library rather than maintain one within the INN source tree.
