automatic authentication in Oracle 8 sqlplus

Hi,
Wonder if anybody can tell me why the following works ok V7 but not so ok in V8 ...

.
.

$ whoami
fred

$ sqlplus system/manager

    grant connect to ops$fred identified by fred;     exit;

$ sqlplus /
.
.

In V7 we get an automatic login as ops$fred but in V8 we get - ORA-01017: invalid username/password; logon denied

Anybody know why this would be so?

Thanks in anticipation.
