George,

Per your suggestion, I used Fiddler to monitor the traffic between CMIS
Workbench and SP. CMIS workbench (as well as my standalone OpenCMIS program=
)
is able to authenticate successfully in 2 tries. However I can't figure out
what credentials are being sent to SP as they are hashed or encrypted, e.g.

Authorization: NTLM TlRMTVNTUAAB...EQ0RTSzAxQkhBVElOQVdFTExJTkdUT04=3D

How did you figure out what this means?

Anyway, when I try the same experiment with OpenCMIS running on Tomcat,
OpenCMIS tries 39 times to authenticate, but the server keeps on returning
401's. OpenCMIS finally gives up. Again, the Authorization headers are
encrypted, so I really don's know what OpenCMIS is trying to do.

Any further pointers on this issue?

Thanks.
Naresh
