** Description changed: tracking bug https://bugs.launchpad.net/ubuntu/+source/adsys/+bug/2078245 [ Impact ] Even if the krb5 ticket is discoverable, the discovery fails (but actually succeeded) So we cannot retrieve the policies or do any action with the controller. [ Test Plan ] - 1. + This is not something that can be easily reproduced in a real + environment, so the best approach to reproduce this issue is: + + 1. Get adsys codebase before the fix. + 2. Run the TestTicketPath test located in internal/ad/krb5_test.go as many times as needed to get the failure (using `go test -count X` runs the test X times). + 3. The test can fail due to krb5_init_context changing the errno without returning any error. [ Where problems could occur ] We now reset errno to 0, because krb5_init_context() can alter it, even if it succeeds. So the discovery always returns success when it succeeds. Worst case would be that discovery failed but errno is set to 0 but this is handled earlier in the code.
