Hi Thomas thank you for your report and your help to make Ubuntu better. I found the associated change at: https://pagure.io/SSSD/sssd/c/fcbcfa69f9291936f01f24b5fcb5a7672dca46f3
That fix is in version 1.14 which means that Ubuntu Zesty and later are already fixed. Adding a bug task fro X/Y - not sure if it applies back to trusty. By the code alone I'd think it does, but one has to confirm with a Test. ** Also affects: sssd (Ubuntu Yakkety) Importance: Undecided Status: New ** Also affects: sssd (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: sssd (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.
