thanks for reply..

As far as ldap is concerned i am pretty new to it still learning/reading 
much stuff on that. I have installed samba using 

Samba 4.1.5 installed on centos 6.3 64bit bare server

After reading some stuff i figured out that ldap is integrated into 
samba (which i don't understand in a broader view like how this is 
working, if someone knows please tell). I just installed phpldapadmin 
thought that i can see ldap database but no success. (just for information)

my setup is pretty simple just to get authenticate through samba4 
whether linux or windows but for linux i am still trying to get things done.
