Hi
So far my understanding If I use sqlnet.authentication_services=none then OS authentication will be eliminated that means user must put password to login as sysdba. But Today I have noticed that it doesn't work. sys user can access the database with OS authentication
$ export ORACLE_SID=test1
$ sqlplus '/as sysdba'
Could anybody share with me , what could be reasons behind this?
I configured the SQLNET.ORA to secure the database , to protect OS authenticate user to access the database. Particularly OS root user.
