[Samba] security vs domain in configuration file

[murali at epiphany.com]

	Greetings!

	When I changed the security = domain in the configuration file, 
	from MS windows, I get Access denied those Unix shares. Whereas, 
	it works if security = server (shown below)

         security = server
         password server = 10.1.3.15

	The Unix Shares are authenticated against NT domain. 

	Any help or clues how to debug this? It has been suggested in this 
	forum it is better to have domain instead of server. Any reasons for
that..

	Thanks,
