Windows xp ticket cache read causes crash

Question

UPDATE Old title: Error calling function Protocol status: 1312 FormatMessage failed with 1815<br>
<br>
I have written an application that authenticates to kerberos using the KerberosLoginModule. It used to work fine on all OS�s. (Windows 98, 2k, xp and Linux tested.)<br>
Now I have upgraded my application to java 1.5 code. And it still works fine on all tested OS�s, except Windows xp. Wich in first case does not even throw�s a error. It just exits in javaws. If I run it manually with java -jar I get the following output:<br>
<br>
Error calling function Protocol status: 1312<br>
FormatMessage failed with 1815<br>
<br>
UPDATE:<br>
After some more messing around I found out it craches because it want to read the ticket cache.<br>
Now I can understand there are some differences in ticket cache versions, but then java could choose not to read the ticket, like under linux. But why does it crash under Windows XP if it only try's to read a ticket? <br>
Now I can only choose between no ticket cache at all on all os's, or to build in a Windows XP filter for the ticket cache option. <br>
Both not very good solutions. Why is this and how can it be solved?<br>

Answer 1

The meeting was quite successful as I can obtain a a ticket from the Win2k KDC now by Acquire TGT using AS Exchange (I have to enter my logon username/password because we have a Novell Logon and not WinLogon...) which results in Commit Succeeded.
But the ticket is not stored in the Windows XP credential/ticket cache, klist tgt says "Error calling function LsaCallAuthenticationPackage: 0
Format message failed with 1815", klist tickets says "Cached tickets: (0)" and kerbtray is empty!
And I stll receive the same error messages as mentioned earlier: "Error calling function Protocol status: 1312
Eine angegebene Anmeldesitzung ist nicht vorhanden. Sie wurde gegebenenfalls bereits beendet."
Do you have any suggestions/ideas what could be wrong with my system/configuration?
