Check Text (C-261399r996617_chk)
If NSS is used by SLEM 5, verify it prohibits the use of cached authentications after one day with the following command:
Note: If NSS is not used on the operating system, this is not applicable.
> sudo grep -i "memcache_timeout" /etc/sssd/sssd.conf
memcache_timeout = 86400
If "memcache_timeout" has a value greater than "86400", the line is commented out, or the line is missing, this is a finding.
