How do I use Windows Authentication to connect to an Oracle database?
Currently I just use an Oracle Username and password however a requirement is to give the user on install the option of selecting Windows Authentication since we offer the same as SQL.
You need to modify the AUTHENTICATION_SERVICES entry in SQLNET.ORA to this:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
As well, you will need to setup the accounts in Oracle to match the Windows accounts. Have a look at http://www.dba-oracle.com/bk_sqlnet_authentication_services.htm for more details.
