LOGIN_RADIUS(8) BSD System Manager's Manual LOGIN_RADIUS(8)
login_radius - contact radiusd for authentication
login_radius [-s service] [-v name=value] user [class]
The login_radius utility contacts the radiusd daemon to authenticate a
user. If no class is specified, the login class will be obtained from the
password database.
When executed as the name login_style, login_radius will request radiusd
use the authentication specified by style.
Available options are:
-s Specify the service. Currently only challenge, login, and
response are supported.
-v This option and its value are ignored.
The login_radius utility needs to know a shared secret for each radius
server it talks to. Shared secrets are stored in the file
/etc/raddb/servers with the format:
server shared_secret
It is expected that rather than requesting the radius style directly (in
which case the radiusd server uses a default style) that login_radius
will be linked to the various mechanisms desired. For instance, to have
all CRYPTOCard and ActivCard authentication take place on a remote server
via the radius protocol, remove the login_activ and login_crypto modules
and link login_radius to both of those names. Now when the user requests
one of those authentication styles, login_radius will automatically for-
ward the request to the remote radiusd and request it do the requested
style of authentication.
LOGIN.CONF VARIABLES
The login_radius utility uses the following radius-specific
/etc/login.conf variables:
radius-server Hostname of the radius server to contact.
radius-server-alt Alternate radius server to use when the primary
is not responding.
radius-challenge-styles Comma-separated list of authentication styles
that the radius server knows about. If the
user's authentication style is in this list the
challenge will be provided by the radius server.
If not, login_radius will prompt the user for
the password before sending the request (along
with the password) to the radius server.
radius-timeout Number of seconds to wait for a response from
the radius server. Defaults to 2 seconds.
radius-retries Number of times to attempt to contact the radius
server before giving up (or falling back to the
alternate server if there is one). Defaults to 6
tries.
/etc/login.conf login configuration database
/etc/raddb/servers list of radius servers and their associated shared
secrets
login(1), login.conf(5)
OpenBSD does not ship with a radius server in the default install, howev-
er several are available via packages(7).
For login_radius to function, the /etc/raddb directory must be owned by
group "_radius" and have group-execute permissions. Likewise, the
/etc/raddb/servers file must be readable by group "_radius".
