Microsoft Front End server deployment requires the installation of a certificate in Deployment Wizard, Step 3: Request, Install or Assign Certificates. To federate with the Avaya Aura® system, the installed certificate must support Server and Client Authentication in the Enhanced Key Usage.
Log in to the Front End server.
Run Deployment Wizard, click Install or Update Skype for Business Server System, and select Step 3: Request, Install or Assign Certificates.
Click Run Again.
Click Default Certificate, and click ViewView Certificate Details.
Verify that the Enhanced Key Usage has the following:
ADDITIONAL INFORMATION: Server Authentication(1.3.6.1.5.5.7.3.1) Client Authentication(1.3.6.1.5.5.7.3.2)
If not, you need to re-create the certificate with Server and Client Authentication and assign to the Front End service.
