37.Os
38.Sh NAME
39.Nm pam_guest
40.Nd Guest PAM module
41.Sh SYNOPSIS
42.Op Ar service-name
43.Ar module-type
44.Ar control-flag
45.Pa pam_guest
46.Op Ar arguments
47.Sh DESCRIPTION
48The guest service module for PAM allows guest logins.
49If successful, the
50.Nm
51module sets the PAM environment variable
52.Ev GUEST
53to the login name.
54The application can check this variable using
55.Xr pam_getenv 3
56to differentiate guest logins from normal logins.
57.Pp
58The following options may be passed to the
59.Nm
60module:
61.Bl -tag -width ".Cm pass_as_ruser"
62.It Cm guests Ns = Ns Ar list
63Comma-separated list of guest account names.
64The default is
65.Dq Li guest .
66A typical value for
67.Xr ftpd 8
68would be
69.Dq Li anonymous,ftp .
70.It Cm nopass
71Omits the password prompt if the target account is on the list of
72guest accounts.
73.It Cm pass_as_ruser
74The password typed in by the user is exported as the
75.Dv PAM_RUSER
76item.
77This is useful for applications like
78.Xr ftpd 8
79where guest users are encouraged to use their email address as
80password.
81.It Cm pass_is_user
82Requires the guest user to type in the guest account name as password.
