How to enable NTLMv2 authentication in DLP jCIFS configuration?

Resolution:

Step 1 : NTLMv2 authentication is not enabled by default in DLP jCIFS configuration. To enable NTLMv2 in jCIFS - edit /Vontu/Protect/config/Jcifs.properties, and replace

jcifs.smb.lmCompatibility=1

with

jcifs.smb.lmCompatibility=3

(refer http://davenport.sourceforge.net/ntlm.html#ntlmVersion2 for different LM, LMv2, NTLM, NTLMv2 authentication mechanisms)

Step 2: Recycle Network Discover to read the new property values.
