sssd update issue

[Stuart Scharf <ss@ll.mit.edu>]

Recently on my testing machine did an "sudo apt-get dist-upgrade" and 
after a bit
my screen saver (with password lock) kicked on.  Meanwhile sssd was half 
installed
(and not functional) when apt hit a question (for sssd actually) and 
stopped.  Now I
couldn't unlock my screen saver because sssd wasn't running. This seems 
like a bug
somewhere in the process, but I have no idea who's bug it is.
