DataSource in WAS7 and Oracle DB Kerberos

I've got user in Oracle DB which is created as "identified externally" and logs in开发者_运维百科 via Kerberos. Is it possible to configure WAS7 DataSource to establish connection under this user?

When user in Oracle is created as "identified by password" there is no problems, I just create in WAS7 JAAS J2C Authentification Data and set it as "Component-managed authentification alias".
