|
|
The SecureTTY service module for PAM
|
|
provides functionality for only one PAM category:
|
|
account management.
|
|
In terms of the
|
|
.Ar module-type
|
|
parameter, this is the
|
|
.Dq Li account
|
|
feature.

It also provides null functions for authentication and session
|
|
management.
|
|
.Ss SecureTTY Account Management Module
|
|
The SecureTTY account management component
|
|
.Pq Fn pam_sm_acct_mgmt ,
|
|
returns failure if the user is attempting to authenticate as superuser,
|
|
and the process is attached to an insecure TTY.
|
|
In all other cases, the module returns success.
|
|
.Pp
|
|
A TTY is considered secure if it is listed in
|
|
.Pa /etc/ttys
|
|
and has the
|
|
.Dv TTY_SECURE
|
|
flag set.
|
|
