Java SE (Java Platform, Standard Edition)

An update:

After installing Java 1.5, the error has become a little more clearer. Instead of the old "no support for encryption type (14)", I now have "KrbException: Invalid argument (400) - Cannot find key of appropriate type to decrypt AP REP - RC4 with HMAC".

However, Ethereal still says des-cbc-md5 is what the AP REP is encoded in (incidentally I got both client and server using des-cbc-md5 over des-cbc-crc). If this is correct, the only conclusion I can come to is that IE or the local system is somehow modifying the HTTP message before it gets decoded by java. Is this even possible or is Ethereal wrong?

There is a link to an answer for this question.

In Windows2xServer, you have to change encryption type for acconut:
+Open Active Directory Users and Computers
+right-click at account --> Properties
+Click the Account tab ->Check "Use DES encryption types for this account

Hope this helps.

The Microsoft article for Windows 2003, 833708 at

http://support.microsoft.com/default.aspx?scid=kb;en-us;833708

describes a registry change to allow the client to specify the encryption type.

Will that solve this problem as well?

Thank you.
