SmbSession.logon successfull whether provide wrong password or right

Hello,

I am using jcifs 1.3.17 jar and when i try to logon with correct user name
and wrong/right password, it authenticates and lands me to successfull page.
And also, throws SmbException everytime. SmbException parameter is incorrect
when lmcompatibility set to 0 and useExtendedSecurity set to false.
SmbException
jcifs.smb.NtlmPasswordAuthentication.nTOWFv2(NtlmPasswordAuthentication.java:209)
when lmcompatibility set to >=3 and extendedSecurity set to true.
Please help.

Regards
Prachi
