I currently have odp.net 9.2 and am using OS Authentication. When I try to use it with VB.NET after referencing system.data.oracleclient, and the connection string:
"user id=/;data source=my.database.com" I get an ora-01005 null password error.
When I log into Toad, as user / and blank password, it works fine.
I tried "user id=/;password=;data source=my.database.com" to no avail.
