Replacing a TLS certificate for VCF management components using an externally signed certificate in the VCF Operations UI is successful.
Replacing the certificate via API with the call "/lcm/locker/api/v3/certificates/{caType}/replace" fails with an error when entering 'external' as the caType:
external CA does not exist
VCF Operations 9.x
The only currently supported option for caType when replacing a certificate via API is 'msca'
