OK, I think I figured this out, at least partially:

It turns out that you really need to specify the 'ccache' parameter to pam_krb5
but in the correct format:

auth            required        pam_krb5.so             no_warn try_first_pass ccache=FILE:/tmp/krb5_%u

Furthermore, do not test logging in with a user that has both a local account
and a kerberos principal -- it may confuse you :-/

For the record here is the /etc/pam.d/sshd that I think works:

# auth
auth            required        pam_nologin.so          no_warn
auth            sufficient      pam_opie.so             no_warn no_fake_prompts
auth            requisite       pam_opieaccess.so       no_warn allow_local
auth            required        pam_krb5.so             no_warn try_first_pass ccache=FILE:/tmp/krb5_%u

# account
account         required        pam_krb5.so
account         required        pam_login_access.so

# session
session         required        pam_permit.so

# password
password        required        pam_krb5.so             no_warn try_first_pass


- I still don't get a valid cache file with a user that also has a local
  password (manually doing kinit works just fine). This is really strange..
- there's a strange 2-3 second delay when logging in, that I can't explain.
  It feels like some sort of timeout but I can't figure out what...

Anyone recognize this? And again, if there's someone out there with a working
setup, I'd love to see the config files.


This sentence contradicts itself -- no actually it doesn't.
