the version installed is Version 3.4.7(lucid packages), the 
configuration files (given below) were working
as is on Ubundy hardy, the winbind issue started only when I migrated to 
lucid.

knit works and smbd and nmbd processes starts up as well:

The same adserver and these same configuration files, including the same 
DNS settings on
the samba machine works fine when I were using Ubuntu hardy 
distribution.  I tried googling
for this issue and tried on my own but could not resolve this.

Thanks in advance
