Fix Recommendation

Configure the policy value for Computer Configuration >> Administrative Template >> System >> KDC >> Allow name-based strong mappings for certificates to "Enabled".

The policy must contain exactly one certificate thumbprint per rule, with each rule represented as a tuple. Thumbprints must be unique and cannot be repeated in multiple rules. The sections of each tuple that are separated by semi-colons must be in the stated order, while the fields separated by commas can be in any order. The rules themselves are separated by new lines.
