[Flow] new typo3_flow_security_account table? I need a quick fix.

[mario chiari]

Hi

I see that  typo3_flow_security_account has lost the field 'roles' in
the latest version of Flow 2.0. (correct?). 
Now, I am trying to move a toy extension of mine to that latest version,
and everything is downhill but that missing field.

If the old INSERT was something like:

INSERT INTO `typo3_flow_security_account`
(`persistence_object_identifier`, `party`, `accountidentifier`,
`authenticationprovidername`, `credentialssource`, `creationdate`,
`expirationdate`, `roles`) VALUES 
('2f8...', '7ba0...', 'EditorBlog', 'BlogProvider', 'bcrypt=>$2a
$14....', '2013-04-22 12:51:43', NULL,
'a:2:{i:0;s:11:"Editor_Blog";i:1;s:12:"Editor_MyExt";}');

where do I insert that last value 'a:2:{}' in the new setting?
Something else I need to be aware?
thanks 
cheers
