I got this error message(see attached image) when trying to bind a certificate from a CA.
I generated a CSR on ACS 5.1 and sent it to the CA to get signed. I got a certificate from the CA which I tried to bind. I went to System Administration -> Configuration -> Local Server Certificates -> Local Certificates to created a certificated and chose the Bind certificate option. I then browse to the certificate I got from the CA and click finish but got this error message.
What is wrong with the certificate that failed validation? Is it my configuration at the ACS or is it the CA? I have decoded the certificate to compare the details and nothing wrong there. I have a seconds ACS which I did the same thing and had the same problem.
