WebGates Configuration Fails during Authentication
During authentication, WebGates configured with the user-defined parameter
hmacEnabled=true in environments where the server-side
globalHMACEnabled property is set to false,
fails.
To solve the issue, apply patch 12.2.1.3.180414 or later and secure the communication
between WebGates and the OAM server. After you apply the patch, ensure that
globalHMACEnabled is set to true. This setting
ensures that the OAM server rejects requests coming from the unpatched
WebGates.
