[jcifs] [SMB/CIFS]Can UID field in SMB header be matched to a Windows SID

[Mikey]

hi,
I want to do a tool to monitor the share folder via capturing the CIFS packet, 
the SMB header of captured packet contains "UID" field, how to know which user
the UID presents?

by the way, if a user login after my monitor application started, I can get 
user name and assined UID pair via  login message. if the use logined before 
monitor application start, I can't know what's the UID means.
