Security Tables-Users,Authorities,Granted_Authorities in Pentaho 5

Hi ,


In Pentaho 4.1 for the external security implementation , we are using the tables Users, Authorities ,granted_authorities from the hibernate database. In Pentaho 5 we are not able to locate these tables in the hibernate, jcrabit and quarts data bases.
In Pentaho 5 which tables are having these datas?

Thanks
