[jcifs] how to investigate authentication failure (with Unix share)

Dear all,
Could you suggest ways to investigate why my very simple code fails to connect to a unix share, from a windows machine?
The failure claims to be an authentication failure, but I am certain my credentials are correct.
This code works fine when accessing windows shares and works fine using a drive mapped to that unix share.
I do not however know enough about unix to figure out what could cause my user not to be able to authenticate when using JCIFS (v1.2.13) to access the share directly.
What follows is a (slightly sanitised) log of the problem.
I am personally incapable of interpreting this trace, so your help will be much appreciated.
Are there questions I should ask of the Unix administrator?
Are there additional flags I can pass to JCIFS?
Is the isLoggedInAsGuest=true relevant?
Thanks
Franck
