Identified externally

 I'm using below command to create a user.

create user myosuser identified externally;

grant connect to myosuser;

alter system set os_authent_prefix='' scope=spfile;

shutdown immediate;

startup;

Then I open a new command prompt and try

sqlplus /

I get invalid username/password

However if I set

alter system set remote_os_authent=TRUE scope=spfile;

shutdown immediate;

startup;

Then in the other window.

sqlplus /

It works. It connects me.,

But the parameter remote_os_authent isn't for remote O/S. Shouldn't I be able to connect without setting this to TRUE.

I'm using Vista and 11.1.0.7
