[jcifs] Domain Controllers

[MSDean at beckman.com]

Mike,

Thanks again.

Are you sure? My test program would seem to indicate that the property change is
taking effect.

In other words, if set the property to a good, then bad, then good domain, the
code succeeds.
If I set it to good, then bad, if fails (see below).

If I do this, the login will SUCCEED.

      static public boolean login (String domain, String username, String
password) {
            boolean isSuccessful = false;
            try {
                  System.setProperty( "jcifs.netbios.wins",
"134.217.244.17,134.217.106.6" );
                  System.setProperty( "jcifs.smb.client.domain", domain );
                  System.setProperty( "jcifs.smb.client.domain", "BADDOMAIN" );
                  System.setProperty( "jcifs.smb.client.domain", domain );
                  // method 1
                  //UniAddress dc = new UniAddress( NbtAddress.getByName(
domain, 0x1c, null));


                  // method 2 (better)
                  NtlmChallenge chal = SmbSession.getChallengeForDomain();
                  UniAddress dc = chal.dc;

                  System.out.println("Test: found a domain controller: host
address=" + dc.getHostAddress() + ", hostname=" + dc.getHostName());

                  SmbSession.logon( dc, new NtlmPasswordAuthentication( domain,
username, password ));

                  isSuccessful = true;
            } catch (SmbException e) {
                  System.err.println(e.getMessage());
            } catch (UnknownHostException e) {
                  System.err.println(e.getMessage());
            }
            return isSuccessful;
      }

If I do this, it will FAIL.

      static public boolean login (String domain, String username, String
password) {
            boolean isSuccessful = false;
            try {
                  System.setProperty( "jcifs.netbios.wins",
"134.217.244.17,134.217.106.6" );
                  System.setProperty( "jcifs.smb.client.domain", domain );
                  System.setProperty( "jcifs.smb.client.domain", "BADDOMAIN" );

                  // method 1
                  //UniAddress dc = new UniAddress( NbtAddress.getByName(
domain, 0x1c, null));


                  // method 2 (better)
                  NtlmChallenge chal = SmbSession.getChallengeForDomain();
                  UniAddress dc = chal.dc;

                  System.out.println("Test: found a domain controller: host
address=" + dc.getHostAddress() + ", hostname=" + dc.getHostName());

                  SmbSession.logon( dc, new NtlmPasswordAuthentication( domain,
username, password ));

                  isSuccessful = true;
            } catch (SmbException e) {
                  System.err.println(e.getMessage());
            } catch (UnknownHostException e) {
                  System.err.println(e.getMessage());
            }
            return isSuccessful;
      }

Once you access jCIFS classes that use properties they cannot be changed.
