Despite changes in the password policy, the database enforces a minimum password length of 8 characters. To see this issue, navigate to Administration -> Security -> Settings in the Security Analytics UI and change the policy to something less than 8 characters. While the policy is not enforced, an exception is written to the /var/lib/netwitness/uax/logs/sa.log file regarding the issue.
The issue does not occur when a password policy is not in place.
This issue has been permanently resolved in Security Analytics 10.5.0.1.
