Hi,
I'm using sssd-1.7.0-5.fc16.x86_64 and during my sssd startup I see this output:

Could you help me in finding the problem?

AVC denials listed in /var/log/audit/audit.log?  SELinux was my first thought
looking at this.

If you do:

setenforce 0
service sssd restart

Does it work then?  If not, it's something else  ;)

stracing the sssd process could give you a pointer as to exactly what it's
trying to do that's failing, in case it's looking in the wrong place or
something.
