UBTU-18-010030 - The Ubuntu operating system must be configured such that Pluggable Authentication Module (PAM) prohibits the use of cached authentications after one day.


If cached authentication information is out-of-date, the validity of the authentication information may be questionable.


Configure Pluggable Authentication Module (PAM) to prohibit the use of cached authentications after one day. Add or change the following line in '/etc/sssd/sssd.conf' just below the line '[pam]'.

offline_credentials_expiration = 1

Note: It is valid for this configuration to be in a file with a name that ends with '.conf' and does not begin with a '.' in the /etc/sssd/conf.d/ directory instead of the /etc/sssd/sssd.conf file.
