[Samba] Ubuntu update broke something in Samba

[Terry Austin]

Ubuntu server 12.04 LTS
Last updates were done (I believe) via apt-get on 3-6-13
Having just completed a full backup, I ran apt-get update and apt-get 
upgrade. There were several updates. I did not particularly note what they 
were.
Samba version 4.1.0pre1-GIT-8ac431a

After that finished, I did some testing. Samba was running. It showed the 
expected shares available. Everything seemed to be working OK, except that 
I could no longer connect with Microsoft's remote admin tools.

After a restore to the brand new backup, everything is back to normal.
