Ranger and Ranger-kms postgresql ssl enabled database

[#1]

Hi,
I have some issues to get SSL working with Ranger/kms with ssl enabled postgresql.
I followed the guides for self signed certificate and how to set it up for Mysql (The only one they have in the documentation with ssl connection).
This failes with An error:

SSL error: java.lang.RuntimeExeption: Unexpected error: java.security.invalidAlgorithmParameterExeption: the trustAnchors parameter must be non-empty ErrorCode: 0


For now i only want the database connection to be ssl enabled, works with ambari to just use ?ssl=true.

Does anyone have any idé why this wont work even if i follow the guide.
