One of the ACS is configured as CA using third party Certificate, But the server certificate on ACS was self generated and is expired.
I tried using the same third party certificate to replace the existing expired server certificate on ACS both by generating CSR on ACS and install new certificate using local storage and read from file options but failed.It gives the following error while using CSR generated private key
"private key doesnt fit for this certificate"
Next assuming that the installed third party certificate with its own private key can be used to install certificate from the storage gives the following error:
"Cannot get the private key from certificate. It's absent or not marked as exportable"
Again assuming that third party certificate has multi server/seat licences.
Any solution to this issue will be of great help.
