[Samba] Samba + LDAP + IIS = massive memory usage

It looks like we've fixed this.  It seems msdfs is on by default.  By chance
I disabled it:

host msdfs = no

No more memory leak!

At some point I will endeavour to recreate the old problem on a test box and
find out why msdfs causes the memory leak and report back to the list.

Thank you for all your help.
