[Samba] Auto creation of home directories on Samba-3.5.4(CentOS 6) using PAM authenticating via ADS

[Derek Cordeiro]

Hi,

I have installed samba 3.5.4 on Centos 6 and have set it up to
authenticate to a Windows 2008 Domain Controller. When I do a "su -
some-domain-user", the home directory gets created. However, I want
the home directory to be created when a user accesses the samba
shares(no shell access). Following are the relevant configurations.
What are the PAM changes I need to make? Help is much appreciated.

==smb.conf==
[global]
   workgroup = RADON
   realm = RADON.LAB
   security = ads
   idmap uid = 16777216-33554431
   idmap gid = 16777216-33554431
   template shell = /sbin/nologin
   winbind use default domain = true
   winbind offline logon = false
   domain master = no
   obey pam restrictions = yes

        server string = Samba Server Version %v
        log file = /var/log/samba/log.%m
        max log size = 50
        passdb backend = tdbsam

[homes]
        comment = Home Directories
        browseable = no
        writable = yes

[public]
        comment = Public Stuff
        path = /home/shared
        public = yes
        writable = yes
        printable = no
