How to audit samba share

[apachenewby]

Hello,

I have samba 3.0.22 running on Ubuntu LTS.
It's integrated with Active Directory.
Is there a way to audit a samba share like when a user deletes or moves something on samba share, to log? Or if it logs by default, where would I look for the log? I checked /var/log/samba/ but nothing in there shows the deletion or anything, just the connections made.

My current smb.conf looks like this:
# Global parameters
[global]
workgroup = CAB
realm = CAB.HOMES.COM
server string = sam
security = ADS
lanman auth = No
client lanman auth = No
client plaintext auth = No
log file = /var/log/samba/%m.log
max log size = 50
name resolve order = wins hosts bcast
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
wins server = 10.10.10.10
domain master = No
local master = No
ldap ssl = no
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
invalid users = root,nobody
cups options = raw
