After upgrading the Centrify DC agent from v4.x to v5.1.x or higher, it has resulted in a large increase in informational messages written to /var/log/messages by adclient.
Answer:
Centrify DirectControl version 5.1 and higher introduced the logging of INFO AUDIT_TRAIL messages. This can lead to excessive logging causing the /var/log/messages file to become very large.
Customers should verify the steps included in KB-2111 and KB-4108 first.
If the steps from those KB's does not stem the INFO AUDIT_TRAIL messages please do the following:
1. Add the following parameter to the /etc/centrifydc/centrifydc.conf file:
audittrail.targets: 0
2. Run adreload as root
This will stop the messages as setting 'audittrail.targets 0' in the configuration file makes logging be more like the logging in the version 4 agent as the 4 agent did not include the audit trail logging.
