Looks like NIM is getting a TGT with AES256 (enctype 18).
And your KDC supports it too.
It looks like your java is version 5 See:
http://java.sun.com/javase/6/docs/technotes/guides/security/jgss/jgss-features.html
>>>DEBUG <CCacheInputStream>
>>> KrbCreds found the default ticket granting ticket in credential cache.
>>> unsupported key type found the default TGT: 18
>> Acquire default native Credentials
>>> Found no TGT's in LSA
Looks like the Java obtained TGT is using DES.
>>>KinitOptions cache name is C:\Documents and Settings\santi\krb5cc_santi
>>>DEBUG <CCacheInputStream> client principal is santi at ZIGIA.ORG
>>>DEBUG <CCacheInputStream> server principal is krbtgt/ZIGIA.ORG at ZIGIA.ORG
>>>DEBUG <CCacheInputStream> key type: 1
But the Java version you are running supports DES, DES, RC4, 3DES and 3DES
>>> Credentials acquireServiceCreds: same realm
Using builtin default etypes for default_tgs_enctypes
default etypes for default_tgs_enctypes: 3 1 23 16 17.
