[jcifs] jCIFS NTLM in clustered WebSphere

[Eric Glass]

This is likely caused by the fact that the NTLM challenge is specific
to the SMB connection for which it was generated.  Basically, if the
client hits Server A in the cluster first, and gets a challenge, it
needs to respond to Server A; if the response is routed to Server B,
that server will create its own SMB connection to the domain
controller, and the response will not be valid for the new connection.
 This results in an authentication failure (and the prompt to log in).

Can you use sticky sessions (i.e., a client is always sent to the same
server in the cluster)?  That might fix the issue.
