Check Text ( C-22909r411076_chk )
If MongoDB is configured to authenticate using SASL and LDAP/Active Directory check the saslauthd command line options in the system boot script that starts saslauthd (the location will be dependent on the specific Linux operating system and boot script layout and naming conventions). If the "-t" option is not set for the "saslauthd" process in the system boot script, this is a finding. If any mongos process is running (a MongoDB shared cluster) the "userCacheInvalidationIntervalSecs" option can be used to specify the cache timeout. The default is "30" seconds and the minimum is "1" second.

Fix Text (F-22898r411077_fix)
If MongoDB is configured to authenticate using SASL and LDAP/Active Directory modify and restart the saslauthd command line options in the system boot script and set the "-t" option to the appropriate timeout in seconds. From the Linux Command line (with root/sudo privs) run the following command to restart the saslauthd process after making the change for the "-t" parameter: systemctl restart saslauthd If any mongos process is running (a MongoDB shared cluster) the "userCacheInvalidationIntervalSecs" option to adjust the timeout in seconds can be changed from the default "30" seconds. This is accomplished by modifying the mongos configuration file (default location: /etc/mongos.conf) and then restarting mongos.
