Comment 61 for bug 1854363

Gah. Will get back into it.
Yes, I was using ldap.adams.edu.

I _think_ it might be because I only moved the `SimpleBind` operation to dispatch to STS. That's the first operation which performs a IO Send, and it's the first Send which kicks off the handshaking. I left the others because I figured it'd be better land the least-disruptive fix possible first.
But Jorg's trace has the handshaking happening during the `SearchExt` operation. I suspect it's either a timing thing, or depends on how you initiate the lookup (maybe some paths don't bother performing the simplebind if the username/password are empty).
Either way, the other operations should be moved onto the STS thread anyway, so I'll start on that.
