We have successfully used jcifs-ext 0.9.4 in our J2EE application server for
SSO with Kerberos (Windows 2000 Active Directory), but the caveat is, we
didn't know how to use it with keytab so we ended up putting the password of
the SPN in domain.xml in plain text. Also, we don't know how to configure a
failover domain controller. Otherwise, it works.
There was also a bug in J2EE 1.4 SDK which stop it from working, but has a
The web.xml I used has the following lines:
<param-value>HTTP/server.int.company.com at INT.COMPANY.COM</param-value>

The problem isn't ports. The DC looks like it's requiring extended security
negotiation (NTLMSSP) which jcifs does not support. You can try setting
jcifs.smb.lmCompatibility = 3.
Or you could use jcifs.http.domainController to use a man-in-the middle
approach but that will be a little slower and will put load on the machine
being used as the "DC".
The jcifs-ext package might help if you just want to do Kerberos SSO but
it's not as easy to use and isn't as tested as mainline.
If you have a budget you should just use Wedgetail. I think they support
what you want.
