I just built a test server running OpenSuSE 12.1 and am trying to learn how configure sssd, but am not sure where to begin to look for why my config cannot allow me to authenticate.
server:/etc/sssd # cat sssd.conf

services = nss,pam
domains = test.local

If I log onto the server as root I can su into an ldap user, however if I try to console locally or ssh remotely I am unable to authenticate.
getent doesn't show the ldap entries for users, Im not sure if I need to look at LDAP, nsswitch, or what:
