[jcifs] Patch for session security support

[Gerrit Meinders]

Using jcifs 1.3.3 we encountered a problem connecting to a share on an 
old Windows 95 machine. It turns out 'session security' is no longer 
supported in newer version of jcifs. This patch restores the support 
that was present in jcifs 1.2.1.
