So ... how do you detangle that?  The only thing that I can come up with is that the login process does the kinit functionality on the users behalf.

I found that I had to do all of this using SASL. 


I remember it as SASL would handle the kerberization during boot up getting tickets for each LDAP entry that you wanted mapped to a service on that client.

I could be wrong but I think SASL seems to be way connect services on Linux with LDAP that are served kerberized.


Thanks,
