44.Sh NAME
45.Nm pam_tacplus
46.Nd TACACS+ authentication PAM module
47.Sh SYNOPSIS
48.Op Ar service-name
49.Ar module-type
50.Ar control-flag
51.Pa pam_tacplus
52.Op Ar options
53.Sh DESCRIPTION
54The
55.Nm
56module provides authentication services based
57upon the TACACS+ protocol
58for the PAM (Pluggable Authentication Module) framework.
59.Pp
60The
61.Nm
62module accepts these optional parameters:
63.Bl -tag -width ".Cm use_first_pass"
64.It Cm use_first_pass
65causes
66.Nm
67to use a previously entered password instead of prompting for a new one.
68If no password has been entered then authentication fails.
69.It Cm try_first_pass
70causes
71.Nm
72to use a previously entered password, if one is available.
73If 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 = Ns Ar pathname
82specifies a non-standard location for the TACACS+ client configuration file
83(normally located in
84.Pa /etc/tacplus.conf ) .
85.It Cm template_user Ns = Ns Ar username
86specifies a user whose
87.Xr passwd 5
88entry will be used as a template to create the session environment
89if the supplied username does not exist in local password database.
90The user
91will be authenticated with the supplied username and password, but his
92credentials to the system will be presented as the ones for
93.Ar username ,
94i.e., his login class, home directory, resource limits, etc.\& will be set to ones
95defined for
96.Ar username .
97.Pp
98If this option is omitted, and there is no username
99in the system databases equal to the supplied one (as determined by call to
100.Xr getpwnam 3 ) ,
101the authentication will fail.
