Not enough room for authentication data error

[Operator]

Hi,

I am using Kerberos 5-1.4.2 on Solaris 9 and Window 2000 as the KDC.

I am trying to login automatically login with from the unix host to
the same unix host without having to type in a password, i.e. I
should be able to use the host principal.

However, I get "Not enough room for authentication data" and a
password prompt.  I type in my Window's password and successfully
login.

How can I troubleshoot this so that typing in a password is not
needed?

Here is some debugging information:
