Hi, I run sssd on Linux Mint 15, I received and installed a raft of sssd updates today. I immediately lost the ability to connect to the domain. The problem was that whilst there was a sssd.pid in /var/run/ ps ax didn't show any sssd programs and if you tried to restart sssd, it just hung. The machine would not turn off, you had to hold the power button to stop it. In the end I downloaded 1.10.1 and compiled & installed it over the installed sssd, everything now works again.
