42.Nd RADIUS authentication PAM module
43.Sh SYNOPSIS
44.Op Ar service-name
45.Ar module-type
46.Ar control-flag
47.Pa pam_radius
48.Op Ar options
49.Sh DESCRIPTION
50The
51.Nm
52module provides authentication services based
53upon the RADIUS (Remote Authentication Dial In User Service) protocol
54for the PAM (Pluggable Authentication Module) framework.
55.Pp
56The
57.Nm
58module accepts these optional parameters:
59.Bl -tag -width Fl
60.It Cm use_first_pass
61causes
62.Nm
63to use a previously entered password instead of prompting for a new one.
64If no password has been entered then authentication fails.
65.It Cm try_first_pass
66causes
67.Nm
68to use a previously entered password, if one is available.
69If no
70password has been entered,
71.Nm
72prompts for one as usual.
73.It Cm echo_pass
74causes echoing to be left on if
75.Nm
76prompts for a password.
77.It Cm conf Ns = Ns Ar pathname
78specifies a non-standard location for the RADIUS client configuration file
79(normally located in
80.Pa /etc/radius.conf ) .
81.It Cm nas_id Ns = Ns Ar identifier
82specifies a NAS identifier to send instead of the hostname.
83.It Cm template_user Ns = Ns Ar username
84specifies a user whose
85.Xr passwd 5
86entry will be used as a template to create the session environment
87if the supplied username does not exist in local password database.
88The user
89will be authenticated with the supplied username and password, but his
90credentials to the system will be presented as the ones for
91.Ar username ,
92i.e., his login class, home directory, resource limits, etc.\& will be set to ones
93defined for
94.Ar username .
95.Pp
96If this option is omitted, and there is no username
97in the system databases equal to the supplied one (as determined by call to
98.Xr getpwnam 3 ) ,
99the authentication will fail.
100.It Cm nas_ipaddr Ns Op No = Ns Ar address
101specifies a NAS IP address to be sent.
102If option is present, but there is no value provided then IP address
103corresponding to the current hostname will be used.
