Toad for Oracle on Mac - Kerberos Authentication. Based on Oracle Support Doc ID 2658307.1 , Kerberos with instant client was added in 21.2. However Toad for Oracle on Mac ( 2025 R1 ) includes Oracle client 19.25. Are there plans to upgrade the Oracle Client bundled with Toad for Oracle on Mac ?
yes there is a work around. Establish connection via sqlplus using instant client 21.2 or above ( I am using 23.3 ) , that will update the cache and then you can use Toad for Oracle on Mac with that connection
The MOS link specifically targets the native macOS Instant Client. Toad for Mac is the Windows version of Toad, which uses a compatibility layer to run on macOS. As a result, the bundled client is the Windows version. Are you encountering issues?
Yes, the issue that I am having is that Toad for Oracle on Mac 2025 R1 will not establish the connection using kerberos authentication. When trying to connect I get "ORA-12638: Credential retrieval failed".
I have found a workaround, by establishing the connection using my Oracle client 23.3 first, the connection works because my 23.3 instant client updates my kerberos cache file where as the Oracle client 19.25 included with Toad does not.
Just curious - does it solve the problem if you:
- hide the files in the 19c instant client folder into a subfolder
- unzip a 23c instant client there to replace the 19c client
If so, maybe in the next version we can include a couple of instant client versions instead of just one.
