CORBA/C++(returning reference to object)

[TVR]

Hi
I am busy writing a program in CORBA.It is about a bank and it's accounts .I am doing this in CORBA.The client has to enter he's name and password.Then these details should be send to a function in the header file
open(name,passw) which should greate a new account if the name is new else it should return a reference to the already greated account.
I have declared a struct Person which contain each client's name,password and balance.
I have used a map to store the details of each user and his details.
To create an account I just add to the map,but how should I return a reference to an already created account ?
(Would it be possible to use an iterator ?.I could search for the account in the map and return the iterator to the main function.)

I aprreciate any help
Thanks
