I currently have samba version 3.6.9 running on Ubuntu 13.04. Does this package come precompiled with --with-ctdb option? If not, I would like to build it but the directions on http://ctdb.samba.org/building.html page is not too clear on samba3. I downloaded source samba-3.6.21 but I don't see any directory called "samba_3_0_ctdb" Can someone shed some light on this please? Thanks in advance.
