So I am feeling rather frustrated with sssd today: 1. I see that when you install sssd (this is centos 6), sssd.conf is not created. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/about-sssd.conf.html implies that if I want to use sssd I need to create the sssd.conf file first. Any reason why? 2. I also noticed if sssd.conf is not there, authconfig won't create it even if you tell it to --enablesssd. How so? I thought that if you are using sssd, it would have stuff like kerberos and ldap (to pick a couple of examples) configured there. 3. It seems if I want to, say, define ldap_user_search_base I must do it directly in sssd.conf instead of passing some kind of argument to authconfig. Am I correct? If so, which files does authconfig affect? I thought it was the *proper* way to configure all the authentication thingies so to make sure they all played together. But, it seems that you have to configure sssd.conf and then use authconfig... or not. Brain hurts
