4.4. Authentication

The identitiy of a user is authenticated after his login. The identity and the method he was The aspect of authentication is configured in the subsection Authentication of the AAAA section in the server configuration.

4.4.1. Requirements

In order to use authentication in Wolframe you have to configure the loading of the module implementing it. The authentication mech explained here as example is implemented in the module mod_auth_textfile. For using it you have to declare the module mod_auth_textfile in the LoadModules section of your configuration before.

4.4.2. Configuration settings

The following table shows the configuration settings for Authentication in Wolframe.

Table 4.1. Authentication configuration settings

NameParameterDescription
RandomDeviceaddress or pathSpecifies the random device to be used. This configuration setting is optional. The system should have a reasonable default for most applications.
TextfilesectionSpecifies the block with the configuration for authentication based on a textfile with WOLFRAME-CRAM as authentication mech.

4.4.3. Example configuration

The following example shows an Authentication configuration with the Wolframe textfile authentication module that provides an authentication over the "WOLFRAME-CRAM" protocol: 

AAAA
{
    Authentication
    {
        randomDevice /dev/urandom
        TextFile
        {
            identifier "TextFileAuth"
            file /var/tmp/wolframe.auth
        }
}

4.4.4. Authentication mechs

Currently only the authentication protocol for WOLFRAME-CRAM is implemented. The client can choose between no authentication (if configured to allow no authentication) or WOLFRAME-CRAM. You configure it as shown in the example above. For the setup of a client see the chapter "Clients".

4.4.5. Development status

We are currently developing other authentication methods like PAM, SASL and database based authentication implementing WOLFRAME-CRAM

. They will be subject of the next release.
