    Default HTTP ERROR 400 - Problem accessing /service/preauth

    Hello,

    one mailbox cannot be used; after trying to login with valid creds 'wrong username or password' message is shown. Logging to the mailbox from the admin interface brings:


    HTTP ERROR 400

    Problem accessing /service/preauth. Reason:

    hmac failure

    Powered by Jetty://

    Tried to change the user status without effect.

    Thanks for any hint.

    Regards,

    Adrian

    Please check the data/time on your servers. If they are off by more than 5 minutes preauth will fail.
