question on ROLE

Hi,

I have a question regarding EXTERNALLY option in creating a role such as,

SQL> CREATE ROLE MANAGER IDENTIFIED EXTERNALLY; when your database users are identified by OPS$username which allows the users to log into the database as "/".

In the manual,

EXTERNALLY:	The operating system verifies the user enabling to the
		role.  Depending on the operating system, the user may
		have to specify a password to the operating system
		when enabling the role.

What is the relationship between EXTERNALLY and OPS$ when creating roles?

Thanks in advance.
