Yes, you can just do it through the sqlnet layer. You'll need In client sqlnet.ora files SQLNET.AUTHENTICATION_SERVICES=3D (NTS) Other authent options can follow NTS, just make sure it's first in the = parentheses. In instance configuration (spfile or init.ora) Either OS_AUTHENT_PREFIX =3D "" Place whatever value you wish to prefix the usernames between the = quotes. Leave the quotes empty for a null prefix. This will allow = "loose" external validation, where any matching user name will be = allowed access (i.e. allows spoofing by LOCALMACHINE\username of = DOMAIN\username accounts). Or OSAUTH_PREFIX_DOMAIN =3D true When used in conjunction with 'CREATE USER "DOMAIN\username" identified = externally' will enforce "strict" external validation (i.e. avoids the = spoofing problem of the first method).
