ISE can not Import Server Certificate

Hi,

If you generated the CSR on the ISE node locally, you are choosing the wrong option. Please use the "Bind CA Signed Certificate" option instead. The private key is generated already when you created the CSR on the ISE.

As far as your 2nd question what are you doing to get this error? Are you generating a bogus private key file and trying to import this?

Thanks,

Tarik Admani

b. Add the CA certificate as a trusted certificate

Step 3: Create a certificate signing request (CSR)

Go to Administration > System > Certificates > Local Certificates, and click Add

b. Generate a certificate signing request

c. Export the CSR from Administration > System > Certificates > Certificate Signing Requests

d. Once saved, open the .PEM file with notepad and copy the entire contents to the clipboard.

Step 4: Submit the CSR to the CA for signing

Step 5: Bind the certificate to the signing request

Step 6 :Confirm that the new ISE certificate is being used
