----------------------------------

I agree with Kai's point, we can fix it in RC3.

>                 Key: DIRKRB-537
>                 URL: https://issues.apache.org/jira/browse/DIRKRB-537
>             Project: Directory Kerberos
>          Issue Type: Bug
>    Affects Versions: 1.0.0-RC2
>            Reporter: Gerard Gagliano
>
> In the following scenario, Kerby is configured for PreAuth required.
> 1. A login attempt causes Kerby to respond with a PreAuth required error.
> 2. A subsequent AS Request containing timestamped PreAuth data (where the password is
correct) causes Kerby to send an AS Reply containing a ticket (it worked).
> 3. A subsequent AS Request containing timestamped PreAuth data (where the password is
incorrect) causes Kerby to not send any Reply back to the client - failing silently except
for the log message "Integrity check on decrypted field failed".
> In the above scenario, MIT Kerberos, sends back a Reply error code 31 (integrity check
failed) with e-text field containing "PREAUTH_FAILED".
