Retrieving Username,Password and DabaBase in Oracle Reports 10g

Hi friends.

any one have how can i retrieve the current username ,password  and database from a report in oracle reports 10g ?, (i need it to call a drill down report, so i need to pass this data to the datailed report ).

in forms, i use get_application_property, but in reports ?

i read some issues and found i can use this function, but it seems like if this function looks for the username and password in an enviroment file (i don't want to place this is a file for later retrive it, i need to get in from some oracle report function) :
