[jcifs] Error "Null setup prohibited"

[Sander, Andreas]

Hello,
 
I have a web server that uses the NtlmHttpFilter. The server has this
config:
 
  <filter>
    <filter-name>NtlmHttpFilter</filter-name>
    <filter-class>jcifs.http.NtlmHttpFilter</filter-class>
     <init-param>
        <param-name>jcifs.http.domainController</param-name>
        <param-value>192.168.1.11</param-value>
    </init-param>
    <init-param>
        <param-name>jcifs.smb.client.domain</param-name>
        <param-value>MYDOMAIN</param-value>
    </init-param>
    <init-param>
        <param-name>jcifs.smb.client.username</param-name>
        <param-value>myuser</param-value>
    </init-param>
    <init-param>
        <param-name>jcifs.smb.client.password</param-name>
        <param-value>mypassword</param-value>
    </init-param>
    <init-param>
      <param-name>jcifs.http.basicRealm</param-name>
      <param-value>My Web Server</param-value>
    </init-param>
    <init-param>
      <param-name>jcifs.http.insecureBasic</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>jcifs.http.enableBasic</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>jcifs.smb.lmCompatibility</param-name>
      <param-value>3</param-value>
    </init-param>
  </filter>

The jcifs version is 1.2.19

This works fine when accessing the web server from a windows client. When
accessing the server from a linux client (suse, konqueror) I get this
exception:

java.lang.RuntimeException: Null setup prohibited.

	at jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:114)

Does anyone have a hint, what I could do?

Maybe this is helpful:

The call to:
    public NtlmPasswordAuthentication( String domain, String username,
byte[] challenge, byte[] ansiHash, byte[] unicodeHash )

Has a byte[] of length 0 as ansiHash and unicodeHash when I get the error

Regards
Andreas
