Is it possible to return the response in case of 401 also ?
With the current change - the caller would get same the error - "Rest request error, returning to caller" for 401 and 5xx, if avisess.disableControllerStatusCheck is true.

you had concerns about the behaviour after password change of controller user, for which status code returned will be 419. However, we can change this for 401 as well, but I'm not sure about the consequences of breaking existing yet.

Yes Mayank. It would be great if we can handle 401 too. The Jira AV-97465 was for handling 401. Then we found some issues with 419, and I had raised that concern also.

Hi @monotosh-avi : I tried handling the 401 response as well, but we have failures with existing functionality as this entails overhaul of go sdk. we'll handle 401 resp like 419 in coming time.

In that case, we won't be able to use the updated sdk, instead we'll continue to use the sdk from locally modified vendor. We'll be able to use the latest sdk code when we can get response for 401.

When we say overhaul of SDK, are we referring to existing test suites breaking with the change? @monotosh-avi can you pls share the SDK fork details here where we have modified this?

I have made the change in vendor of AKO, not in an sdk branch. For reference we can check the avisession.go changes in this PR:
