Another cause of Winbind consuming 100% of CPU

[Richard Sharpe]

Another customer hit this. Here is what the log shows:

winbindd/winbindd_dual.c:1358(fork_domain_child)

Somehow they got two domains with the same SID.

How do we repro that?

The fix that Jeremy provided seems to fix this as well.
