Problem
The SMP Connectivity Test is failing on checking the SMP certificate registered in the metadata.
Reason
The SMP certificate used for uploading into the metadata was exported to PEM in a common format with LB+CR control characters to be in column, but when it was copy-pasted into SOAP UI property field - which was used for uploading the metadata - the control characters were converted to spaces.
Therefore the metadata and the original PEM was not identical anymore.
Solution
Please make sure that the PEM certificate of SMP used in metadata should not contain spaces!
