Problem with adding IdP certificate with Acrobat

Hello

Maybe someone in here can assist me. So i am trying to get Single Sign On to work for our organization.

When in the configure directory section i follow the sets provided to copy the cert we use for our AD FS and when i click save i get an error saying

"There was a problem saving your configuration - check the values you entered and make sure you are uploading a valid (PEM base64-encoded X.509) certificate."

I did save the cert as a base64-encoded x.509 cert too from the FS server.

Is there anything else i could try or any other work around for this anyone might know?

Thank you
