I think you will need 1) to have an entry in file /etc/request-key.conf such as this: create cifs.idmap * * /usr/sbin/cifs.idmap %k 2) winbind configured and running and added to file /etc/nsswitch.conf like this passwd: compat winbind group: compat winbind shadow: compat winbind 3) need a link sudo mkdir /etc/cifs-utils sudo ln -s /usr/lib/x86_64-linux-gnu/cifs-utils/idmapwb.so /etc/cifs-utils/idmap-plugin (dpkg -L cifs-utils | grep so will show you the location in ubuntu e.g) 4) And mount cifs share with option cifsacl Hope that helps. I had a working setup which is not there anymore.
