Oracle 9i/10G DB authentication using Active Directory (with out OID)

Question

Hello All,
We want to use a Single-Password authentication scheme using the Active
Directory as the primary source for userId/Password.
We don't want to use the Active Directory and OID bridge.
As we have many databases and would like to configure all Databases to use Active
Directory for Authentication. Our goal is to have single id/password across all
the databases and any user should be able to login from any computer using their
windows id/password, note that we don't want to use the OSAuthentication.
We have read the documents provided by oracle for authentication using Active
Directory, we were able to create Oracle Schema in Active Directory and were
also able to register a DB with Active Directory and then created user as global
user in Oracle Database and provided the DN of the user. When we tried
authenticate with all this setup it comes back and says invalid ID/Password !!!
And with 10G database we get the Oracle Error ORA-03113: end-of-file on communication channel !!
Has any one tried or have information on Integrating Oracle to Auth against Active Directory?
Envoirnment:
Oracle DB Version: 9.2.0 and also tried on 10.0.1 with same results
Operating System: Windows 2000/ Windows 2000 Server
Constraint: We don't want to user OID ( as we don't have license for this
product ! )

I have a thread started similar to your request.
OS Authenication on Windows
Somewhere I read this. It works on Oracle 9i on Linux, but I have not tried it with Oracle 9i on Windows.
SHOW PARAMETER OS_AUTHENT_PREFIX;
SHOW PARAMETER REMOTE_OS_AUTHENT;
CREATE USER OPS$SOMEUSER IDENTIFIED EXTERNALLY;
GRANT CREATE SESSION TO OPS$SOMEUSER;
For the username, I wonder if we are supposed to put the Windows Domain name as part of the username? Such as, for a Windows domain user MyDomain\SomeUser
CREATE USER OPS$MYDOMAIN\SOMEUSER IDENTIFIED EXTERNALLY;
I really wish Oracle or somebody created a guide or book on how to do this.
