Running sshd with Privilege Seperation drops connection on password change

Allow access to a share for only one machine account
I have two domain controllers running ubuntu (12.04 and 13.10) both with samba (4.1.6 and 4.1.7) installed and running (and with sssd on both machines to retrieve uid/gid from AD). I wish to set a share on ubuntu2 in the way so it could be accessible only from ubuntu1 (and by any user from ubuntu1, for instance by local root). I have found this solution though I'm not sure it solves my issue: http://community.centrify.com/t5/Centrify-enabled-Samba/How-to-allow-Windows-machine-accounts-to-connect-to-a-share-as/td-p/11834 Anyway, it does not work -- klist do...
