I don't have gui, that just a storage server. And it didn't complain 
about permissions, rather recursive snapshots.
So I had to completely whack recursive from 
/usr/share/time-slider/lib/time_slider/zfs.py

         #no need for recursive snapshots!
         #if recursive == True:
         #    cmd.append("-r")

Then changed settings for auto-snapshot.xml and imported it back.

svccfg export auto-snapshot > auto-snapshot.smf
sudo svccfg import auto-snapshot.smf

Manually set false for whatever fs I didn't want snapshots
sudo zfs set com.sun:auto-snapshot:daily=false rpool/ROOT/oi_151a

Seems working now more or less as I wanted it to.
