Comment 6 for bug 531834

Yeah, I thought the u1* connections came from login.u.c, so indeed all the connections we see there should be the ones used by AUTH SLAVE stores.

Unlike I said earlier, though, to have this fixed we need to split the auth tables out of the replication *and* get rid of auth stores from the Launchpad code so that all connections go to the read-only DB when the read-only.txt file exists.
