If no 74password has been entered, 75.Nm 76prompts for one as usual. 77.It Cm echo_pass 78causes echoing to be left on if 79.Nm 80prompts for a password. 81.It Cm conf Ns No = Ns Ar pathname 82specifies a non-standard location for the RADIUS client configuration file 83(normally located in /etc/radius.conf). 84.It Cm template_user Ns No = Ns Ar username 85specifies a user whose 86.Xr passwd 5 87entry will be used as a template to create the session environment 88if the supplied username doesn't exist in local password database. The 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 Ns ), 99the authentication will fail. 100.Sh FILES 101.Bl -tag -width /etc/radius.conf -compact 102.It Pa /etc/radius.conf 103The standard RADIUS client configuration file for 104.Nm 105.El 106.Sh SEE ALSO 107.Xr pam 8 , 108.Xr passwd 5 , 109.Xr radius.conf 5 110.Sh HISTORY 111The 112.Nm 113module first appeared in 114.Fx 3.1 . 115The 116.Nm 117manual page first appeared in 118.Fx 3.3 . 119.Sh AUTHORS 120The 121.Nm 122manual page was written by 123.An Andrzej Bialecki Aq abial@FreeBSD.org . 124.Pp 125The 126.Nm 127module was written by 128.An John D.
