+pam_tty_audit — Enable or disable TTY auditing for specified users
+The pam_tty_audit PAM module is used to enable or disable TTY auditing. By
+default, the kernel does not audit input on any TTY.
+ For each user matching patterns, disable TTY auditing. This overrides any
+ previous enable option matching the same user name on the command line. See
+ NOTES for further description of patterns.
+ For each user matching patterns, enable TTY auditing. This overrides any
+ previous disable option matching the same user name on the command line.
+ See NOTES for further description of patterns.
+ Set the TTY audit flag when opening the session, but do not restore it when
+ closing the session. Using this option is necessary for some services that
+ don't fork() to run the authenticated session, such as sudo.
+ Log keystrokes when ECHO mode is off but ICANON mode is active. This is the
+ mode in which the tty is placed during password entry. By default,
+ passwords are not logged. This option may not be available on older kernels
+ (3.9?).
+When TTY auditing is enabled, it is inherited by all processes started by that
+user. In particular, daemons restarted by an user will still have TTY auditing
+enabled, and audit TTY input even by other users unless auditing for these
+users is explicitly disabled. Therefore, it is recommended to use disable=* as
+the first option for most daemons using PAM.
+To view the data that was logged by the kernel to audit use the command
+aureport --tty.
+The patterns are comma separated lists of glob patterns or ranges of uids. A
+range is specified as min_uid:max_uid where one of these values can be empty.
+If min_uid is empty only user with the uid max_uid will be matched. If max_uid
+is empty users with the uid greater than or equal to min_uid will be matched.
+Please note that passwords in some circumstances may be logged by TTY auditing
+even if the log_passwd is not used. For example, all input to an ssh session
+will be logged - even if there is a password being typed into some software
+running at the remote host because only the local TTY state affects the local
+TTY auditing.
+Audit all administrative actions.
