OK,
Before the call
"auto s = factory.openSession();"
Does de mysql db has a db called 'test' and a table called 'card' 
with columns named 'id' and 'pwd'? If not call:
"factory.getDBMetaData().updateDBSchema( conn, true, true );"
verify the table is created in mysql.
After create call:
"factory.openSession();"
...
If things are still failing take a look here:
https://github.com/buggins/hibernated/blob/master/hdtest/source/htestmain.d
This is a simple program testing some basic functions of 
hibernated. Try it with sqlite first after that add a mysql 
section and try again.
