[Samba] Can u help me

[sachin chadha]

Hello Sir, 
          Can u help me to provide useful information
about the samba. I want to ask few question which are 

1)what security does samba provides from sever side
and client side.

2)What auditing features does samba provides and
finally 

3) Is it possible to detect brute forcing attacks
(such as NAT) against a SAMBA server

I will be very grateful if can give me information on
these.
 
Thanx 
Sachin Chadha
