All right, that makes a lot of sense. I think actually I must have had
something bad in the LDAP entry for me; replacing it with
{SASL}chas@KRBTEST works as intended now. So, it looks like most of my
problem was a lot of little errors that were tripping me up. I feel a
bit stupid, but on the other hand, it's good to know I was at least on
the right track. Thanks for all your help!
