However, I noticed that logins, su, and sudo are all responding slowly. This was all fixed and fine once I updated my configuration files, but this week it's acting up again. Before it was just su and sudo that I noticed as slow (authentication takes around 20 seconds). But now even logins are delayed (xdm or command line).
Whenever I see something that eventually works, but only after a long delay, I think of DNS problems. Who might be doing a nonsensical DNS lookup, I have no idea. But you might consider running a packet sniffer (wireshark, etc) while logging in or doing an su. Are you running your own local name server?
