NAME

radiusd.conf — RADIUS daemon configuration file

DESCRIPTION

radiusd.conf is the configuration file for the RADIUS daemon, radiusd(8). It has the following format:

Empty lines and lines beginning with the ‘#’ character are ignored.

Keywords may be specified multiple times within the configuration file. The configuration options are as follows:

listen on address port port

Specify an address and a port to listen on.

client address/mask {...}

Allow access to a client with the specified address and mask. It is followed by a block of options enclosed in curly brackets:

secret secret

The shared secret with the clients. This option cannot be omitted.

msgauth-required yes | no

Message authentication is required if “yes” is specified.

module load name path

Load module name from path. The following modules are available:

Path	Description
/usr/libexec/radiusd/radiusd_bsdauth	“bsdauth” module
/usr/libexec/radiusd/radiusd_radius	“radius” module

“bsdauth” module

The “bsdauth” module provides authentication from the local system's authenticate(3) interface, known as “bsd auth”. It only supports PAP, password based authentication.

“radius” module

The “radius” module provides authentication from upstream RADIUS servers.

module set key value ...

Configure the module specific configuration by key and value.

The “bsdauth” module supports the following configuration key and value:

restrict-group group ...

Restrict login only if the user is a member of the specified groups.

The “radius” module supports the following configuration key and value:

server address[:port]

Specify the upstream server's address and port. If port is omitted, 1812 is used. This configuration can be specified multiple times.

secret secret

Specify the shared secret with the servers.

max-tries number

Specify the maximum number of retransmissions for a server. radiusd(8) will retransmit 2, 6, 14, 22, and 30 seconds after the first transmission. If the number of retransmissions per server reaches this value, the current server is marked as “fail”, and the next server is used for subsequent requests. The default value is 3.

max-failovers number

If a positive number is specified, radiusd(8) will failover to the next server when the current server is marked “fail”. This key and value specifies the maximum number of failovers. The default value is 0.

request-timeout sec

Specify the request timeout in seconds. If this value is specified, max-tries and max-failover will not be used.

authenticate username-pattern ... {...}

Specify an authentication configuration for the users specified by username-pattern. Use shell globbing rules for the pattern; multiple patterns can be specified by separating with space characters. When multiple authenticate lines are specified, the first authenticate setting whose username-pattern matches an authenticating user is used. It is followed by a block of options enclosed in curly brackets:

authenticate-by module

Specify the module name.
