Authentication with enabled Kerberos

Post by devmar12 » Tue 08 Oct 2019 12:14

HI,

Some time ago we did the Devart.Oracle.Data update from 8.5.478 to 9.7.734, in our own application which our customers use.
Recently, one of them reported that he could not authorize himself in database by receiving the message: ORA-01017 Invalid Username / Password.
The customer uses OCI mode with Kerberos for authentication and claims that using the previous version of our program with Devart.Oracle.Data v.8.5 the connection was working correctly. After upgrading to a newer version of our program containing Devart.Oracle.Data 9.7 above error appears.
Has anything changed between these versions?
How to set up Kerberos authentication in a newer version?

Thanks.

In the OCI mode, our provider passes credentials to Oracle Client, Kerberos authentication is managed completely by Oracle Client. Please make sure that you are using the same Oracle Client with the same settings.
