* `master` * 8a8869994745429b3f5535a5d0b91f1d0b2fa723 - fail_over: protect against a segmentation fault * `sssd-2-9` * f63a54c3d89866949810d5bcdb09bf2edd3ced02 - fail_over: protect against a segmentation fault
This doesn't fix issue per se but should hopefully work around it at least.
Will be shipped as a rebase to sssd-2.9.1.
