I managed to reproduce this issue, however I'm not sure it was related to the 
plugin itself. What seemed to resolve it was update to latest packages in F15 
and restart. However I did a small memory optimization, so I'm sending the 
corrected patch. Please let me know if everything works for you now. In not, 
try attaching gdb to sssd_be process *after* it freezes and send me a 
backtrace.

Thanks
Jan
