impdp or dbms_datapump

I have a DBA (remote) that is trying to change user accounts to a new name. He says he uses datapump REMAP_SCHEMA. and it is supposed to keep the same password.  

However - the interesting thing about what he said was that if he logs in locally, he can use the same password, but if he uses sqlnet from his desktop the password does not work - therefore he as to assign a new password.  

Anyone have any insight into this. Oracle10g and up. Might actually incorporate the username as part for the sys.user$.password?
