-t TTL Enables persistent PAM connections where the connection to
the PAM database is kept open and reused for new logins.

When used for authenticating to local UNIX shadow password databases
the program must be running as root or else it won't have sufficient
permissions to access the user password database. Such use of this pro‐
gram is not recommended, but if you absolutely need to then make the
program setuid root
chown root basic_pam_auth
chmod u+s basic_pam_auth
Please note that in such configurations it is also strongly recommended
that the program is moved into a directory where normal users cannot
access it, as this mode of operation will allow any local user to
brute-force other users passwords. Also note the program has not been
fully audited and the author cannot be held responsible for any secu‐
rity issues due to such installations.
