Perfect timing, I was just starting testing of SSSD (v1.11.5) on Ubuntu 14.04 LTS last night.
Several quesitons, if you can assist as more familiar with (RHEL):
1) Ubuntu 14.04 - for modifying DNS nameserver, what is the correct place to start changes as there are resolvconf, dnsmasq, Network Manager ? DNS nameserver changes in Ubuntu completely mess me up.
2) Ubuntu 14.04 - Samba and winbind are installed, should they be removed before setting up SSSD?
3) SSSD 1.12.5 will be installed with "sudo apt-get install sssd"?
4) For automatic user directory creation, is the correct process to use oddjob_mkhomedir or pam_mkhomedir?
