Possibly, but the easiest thing would just be to try it out and see what 
happens.  Whatever the outcome, it should be consistent and repeatable 
(i.e., problems wouldn't be intermittent, it would either work or not). 
  It may depend on whether you are authenticating directly against the 
domain controller, or whether a NETLOGON authentication channel is 
involved.  If you've got things working with NTLMv1, just set 
"jcifs.smb.lmCompatibility" to "3" to test LMv2.  If it works, you can 
be pretty comfortable it will work with similar accounts.  The issues I 
dimly recall may have just been back when I was testing NTLMv2; LMv2 may 
work properly in all scenarios.
