Dear Kerbros Team,

I need some information about Kerberos error of KRB_ERR_RESPONSE_TOO_BIG.

My question is:
============
1. With our implementation of Kerberos (we are using MIT), we are not seeing 
this error when we use UDP connection in Windows environment. (KDC server is at 
: Windows 2000 server , service pack4). 

But some other kerberos implementation (used same MIT code) is giving the error 
of KRB_ERR_RESPONSE_TOO_BIG with the same Windows KDC Server.

Could you please let me know why we are seeing this difference? Any specific 
reason for this in my implementation?

Thanks a lot in advance,
-Surendra

  AD does have alert messages about KDC failures. Note that the password is 
never
  sent to the KDC. The KDC can only detect a failure if pre-auth is used, and 
the
  client returns a pre-auth response encrypted in the wrong key generated from
  the wrong password and salt.

of preauth failure error?) That means, if I enter the wrong password, the KDC 
server should reply with error. If I enter correct password, KDC should respond 
with SUCCESS message (without considering the preauth failure error). Is it 
possible with krb5 code?
