Affected Product:  See more info
BIG-IP APM(all modules)

Known Affected Versions:
13.0.0, 13.0.0 HF1, 13.0.0 HF2, 13.0.0 HF3, 13.0.1

Opened: Oct 17, 2016
Severity: 3-Major


v13.0 of APM includes a new feature where Client-initiated forms SSO can be configured to monitor web applications to suggest possible configurations to an APM administrator to make it easier to set up. This function utilizes the log file to emit log lines to suggest the configuration of SSO. However the logs for this feature lose approximately 15-30% of content.


Feature may work intermittently because up to 30% of the logs may be lost.


Use new client-initiated forms SSO passthrough configuration feature in v13.0.


Instead of using the new feature to configure Client-initiated forms SSO, instead configure it manually after examining the HTML source code of the target login page.
