I'm trying to setup RADIUS authentification with Oracle 10g R2. Unfortunately, when i try to connect, i get this message:
ORA-12641: Authentication service failed to initialize
I also tried to follow this documentation: http://download.oracle.com/docs/cd/B19306_01/network.102/b14268/asoradus.htm#ASOAG040
But there is no "Oracle Advanced Security" in the choice list. Is it because it's not installed? Is there a way to install it on top of my current installation?
