You are correct, there is no dantolov@RESOURCE.NET; there is
dantolov@IU.EDU, and there is also a local user dantolov with AFS ID 2. I
did not see email@example.com as a member of system:firstname.lastname@example.org at any
time. Are you saying that the presence of the local user is the problem?
Below is what kinit and aklog produce. Thanks,

No, don't do this. In your setup, the _only_ user that will be
recognized as "dantolov" is someone that authenticates with the
principal dantolov@RESOURCE.NET, which, if I understand correctly, does
not exist, so there should not be a user called "dantolov" at all. The
user that authenticates via the kerberos principal dantolov@IU.EDU will
have the AFS PT name "email@example.com" if IU.EDU is not in krb.conf.

aklog is supposed to automatically create the user firstname.lastname@example.org and
add it to system:email@example.com for you; you don't need to do it
yourself. Does firstname.lastname@example.org exist? What does aklog say when you give
it the -d option when you authenticate with dantolov@IU.EDU ?
