Here is the output from the server with LogLevel DEBUG3. I am logging in
with an LDAP account. Logging in normally (ssh ckonstanski at host) works fine.
So any messages claiming that the password is invalid are bunk, unless
sshpass is munging the password. Trying to figure out how to get more
logging on the client end. Any help in this area would be appreciated.

I see what appears to be a failed password lookup. Hard to tell if I can't
determine what it thinks I sent as the password. Hard for me to believe that
sshpass is munging the password though, since I can use it to log onto a
non-Ubuntu server just fine.
