Following are the steps we performed to run vfs and error encountered. Also
attached vfs_demo.c file to look into.

Steps are followed from link above.
[global]

log level = 10
max log size = 1000
level2 oplocks = true
passwd chat = *Enter\snew\s*\spassword:* %n\n
*Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
server role = standalone server
obey pam restrictions = yes
map to guest = bad user
encrypt passwords = true
public = yes
passwd program = /usr/bin/passwd %u
passdb backend = tdbsam
dns proxy = no
server string = %h server (Samba, Ubuntu)
default = share
unix password sync = yes
workgroup = WORKGROUP
os level = 20
guest only = yes
syslog = 0
panic action = /usr/share/samba/panic-action %d
usershare allow guests = yes
max log size = 1000
pam password change = yes
[share]
comment = Ubuntu file server
path = /srv/samba/share
browsable = yes
guest ok = yes
readonly = no
create mask = 0755
vfs objects = full_audit
full_audit:failure = all
full_audit:success = all
full_audit:prefix = %u|%I|%m|%S
full_audit:failure = all !open
full_audit:facility = LOCAL7
full_audit:priority = ALERT
Above details when entered in smb.conf file client successfully connects to
server using map network drive and all the messages are stored in syslog
file.
output when samba runs is :
root at ubuntu:/etc/samba# sudo restart smbd
smbd start/running, process 2619
root at ubuntu:/etc/samba# sudo restart nmbd
nmbd start/running, process 2627
root at ubuntu:/etc/samba# smbclient //localhost/share
-Usome-user%some-password
Unknown parameter encountered: "server role"

smb: \> put vcbbv.txt tesxt1.tx
putting file vcbbv.txt as \tesxt1.tx (1.4 kb/s) (average 1.4 kb/s)

but if we add below part in smb.conf and restart samba , client is unable
to connect to server.
[share]
comment = Ubuntu file server
path = /srv/samba/share
browsable = yes
guest ok = yes
readonly = no
create mask = 0755
vfs objects = vfs_demo
vfs_demo: audit path = vcbbv.txt
//vcbbv.txt is file in shared folder
Output is as follows:
root at ubuntu:/etc/samba# smbclient //localhost/share
-Usome-user%some-password
Unknown parameter encountered: "server role"
Ignoring unknown parameter "server role"
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.3]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME
Also we tried to add entire file name in vfs objects = vfs_demo.so , even
that didnt work
We copied vfs_demo.so file generated in after compiling vfs_demo.c in
/usr/local/samba/lib/vfs
where other vfs*.so files are placed . But vfs_demo modules isnt running.
We also tried debugging smbd process uding GDB but vfs module doesnt seem
to be called.
Thanks.
