pam_timestamp_check

PAM_TIMESTAMP_CHECK(8)						 Linux-PAM Manual					    PAM_TIMESTAMP_CHECK(8)

NAME

       pam_timestamp_check - Check to see if the default timestamp is valid

SYNOPSIS

       pam_timestamp_check [-k] [-d] [target_user]

DESCRIPTION

       With no arguments pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it.

OPTIONS

       -k
	   Instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option.

       -d
	   Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output.

       target_user
	   By default pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as herself. When the
	   user authenticates as a different user, the name of the timestamp file changes to accommodate this.	target_user allows to specify this
	   user name.

RETURN VALUES

       0
	   The timestamp is valid.

       2
	   The binary is not setuid root.

       3
	   Invalid invocation.

       4
	   User is unknown.

       5
	   Permissions error.

       6
	   Invalid controlling tty.

       7
	   Timestamp is not valid.

NOTES

       Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing
       information before noticing that it is not being asked for.

EXAMPLES

	   auth sufficient pam_timestamp.so verbose
	   auth required   pam_unix.so

	   session required pam_unix.so
	   session optional pam_timestamp.so

FILES

       /var/run/sudo/...
	   timestamp files and directories
