> Inside the "SPNEGOLoginModule" (3.0.0.CR2-SNAPSHOT) the run()-Method of inner class "AcceptSecContext" checks for existence of Kerberos-oid within the SPNEGO-Token. But it checks solely the first element of the mechanism-list:
> {code:java}
> 	if (mechList.get(0).equals(kerberos))
> 	{
> 	 gssToken = negTokenInit.getMechToken();
> 	}
> 	else
> 	{
> 	 boolean kerberosSupported = false;
> 	 ...
> {code}
> But SPNEGO-Token from Windows-KDC (2008 R2) supports four types of authentication (oids):
> * oid: 1.2.840.48018.1.2.2 (Windows Kerberos V5)
> * oid: 1.2.840.113554.1.2.2 (Kerberos V5 - we are looking for)
> * oid: 1.3.6.1.4.1.311.2.2.30 NegoEx
> * oid: 1.3.6.1.4.1.311.2.2.10 NTLM
> So Kerberos-check within run()-method should iterate the mechList until it founds Kerberos-V5-oid:
> {code:java}
>                for (Oid oid : mechList)
>                 {
>              	   if (oid.equals(kerberos))
>                    {
>             		   gssToken = negTokenInit.getMechToken();
>                            break;
>             	   }
>                }
> {code}
