radiusd.conf - configuration file for the FreeRADIUS server

The radiusd.conf file resides in the radius database directory, by default /etc/raddb. It defines the global configuration for the FreeRADIUS server.

The file consists of attribute-value pairs, sections, and comments.

Attribute-value pairs are of the form name = value.

A section begins with a section name, followed on the same line by an open bracket {. The section may contain other sections, or attribute-value pairs. The section ends with a close bracket }, on a line by itself.

Any line beginning with a (#) is deemed to be a comment, and is ignored. Lines containing only whitespace are also ignored.

The file is line-based. That is, each newline-terminated line represents either a comment, a section name, or an attribute-value pair. It is not possible to specify multiple items on the same line, and there are no continuation lines.

The value for a particular attribute may reference a previously defined attribute by name. The standard shell reference format ${name} is used. When the variable is in a section or subsection, it may be referenced as ${section.subsection.name}. Forward references are not allowed. Relative references are allowed, via pre-pending the name with one or more of '.'.

The individidual configuration directives are too numerous to list here, so this manual page only documents the file format. Please read the sample configuration file distributed with the server for comments describing each of the allowed configuration directives.

foo = bar

Sets variable foo to have text value bar.

blogs = ${foo}

Sets variable blogs to the value of variable foo from the current section. If there is no variable foo in the current section, then it looks for that variable in the body of the main configuration file, e.g. {Blogdir}

my_section {

baz = bud

}

Defines a section named my_section, containing variable baz.

blogs = ${.foo}

Sets variable blogs to the value of variable foo, from the current section.

blogs = ${..foo}

Sets variable blogs to the value of variable foo, from the section which contains the current section.

blogs = ${modules.detail.detailfile}

Sets variable blogs to the value of variable detailfile, of the detail module, which is in the modules section of the configuration file.
