As far i know, it is as expected… Only the filemaker built-in certificate (for test use) should result to a fail in this particular situation.
To me, it is not obvious that older client versions still are accepted as the problem is not only server related.
This is confusing.
Taking the instructions from http://help.filemaker.com/app/answers/detail/a_id/14568 it is pointing in a MUST Update client direction.
Still, a decent official explanation of this incident would be nice...
Thank you for your posts.
A possible security issue was discovered, so that is the reason for FileMaker Server 13.0v9. FileMaker Pro/Go 13.0v9 will not work with earlier versions of FileMaker Server 13, so it is important that FileMaker Server 13.0v9 is installed first. Once FileMaker Server 13.0v9 is installed, you can still connect with earlier versions of FileMaker Pro/Go, but there is still a potential security issue, so updating to 13.0v9 is recommended.
