NET: Unsupported verifier type error

[clintdavis]

We're trying to connect to an Oracle 12c database using direct mode. When I hit the test connection feature I get the error "NET: Unsupported verifier type". I'm using the latest version (9.2.220.0) because the release notes said it fixed Oracle 12c direct authentication. I know it's not a connection issue because I can use SQL Developer and connect successfully. Am I doing something wrong here? Or is there a workaround for this?

Thanks,
Clint

Also, I tried submitting a support ticket twice and both times I never received any kind of confirmation that it was sent nor did I get a copy to my email when I checked the box. Apologies if this has already been received.

When I hit the test connection feature I get the error "NET: Unsupported verifier type".

1. We cannot reproduce the issue at the moment. Please specify:
a) the exact version (x.x.x.x), capacity (x86 or x64), platform (Linux or Windows) of your Oracle server
b) the value of SQLNET.ALLOWED_LOGON_VERSION_SERVER in sqlnet.ora of your Oracle server
c) could you tell us where (form, wizard, etc) you "hit the test connection"?

Bump.

And I still can't submit a ticket. I hit submit and it comes back to the same page with no errors or confirmation.

When I hit the test connection feature I get the error "NET: Unsupported verifier type".

1. Could you confirm that the error persists with the following code as well?

Code: Select all

    var conn = new Devart.Data.Oracle.OracleConnection();
    conn.ConnectionString = "direct=true;server=****;sid=****;user id=****;password=****;Persist Security Info=true;";
    conn.Open();

If you are using additional connection string parameters, please specify them.

And I still can't submit a ticket. I hit submit and it comes back to the same page with no errors or confirmation.

1. When I run your code I get an exception where the message is "NET: Unsupported verifier type". The inner message is blank.

2.2. I did get a copy a few minutes after I posted here.

2.3. I did not attach any files.
