Management Point Root CA Trust Issue (HTTP 403)

Sat, 06 Apr 2019 00:00:00 +0000

I was setting up a Configuration Manager environment in HTTPS mode and I was running into issues with the server selecting a client authentication certificate.

I was seeing these messages in the MPControl.log.

I was seeing this message in the IIS log.

I was getting a 2148204809 error which translates to A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. That told me something was wrong with the root CA trust. Some searching online brought up a few useful posts on the subject.
