Severity: 3-Major

Symptoms

When a BIG-IP system has an APM Limited license, NTLM is silently disabled and the connection goes through. This breaks many (all) use-cases for Exchange + APM.

Impact

Exchange cannot be used with APM Limited license when NTLM frontend authentication is selected, which is used in essentially all APM + Exchange deployments.

Conditions

APM and Exchange are deployed together with APM Limited / Lite license.

Workaround

None

Fix Information

The NTLM frontend authentication (ECA) feature can now be used with an APM Limited license. Typically, this is for Exchange deployments.
