SOE changed the login server opcodes slightly sometime between Titanium and Seeds of Destruction. You can get minilogin to work for SoD/Underfoot clients by altering the minilogin opcodes.conf as described in this thread:

Trouble is, if you do that, then you can't login with Titanium.
You should use the EQEmuLoginServer. as it can handle all versions of the client simultaneously (Titanium on UDP port 5998 and SoD+ on 5999), plus it has proper password authentication, rather than the IP based auth that minilogin uses.

It's a bit more difficult to setup than minilogin, but there should be some threads on the forums on how to do it.
