error connecting to DB that requires securityMechanism=13

I have no problem connecting to this DB in SQuirrel.  But in datagrip I get the error below.

In squirrel I add this to the end of the DB link.

:securityMechanism=13;

I tried that in datagrip in addition to trying adding the variable/value to the advanced tab in the connection configuration window.  

Any ideas?
