Request help with following problem that has been troubling me since a month:
I have a CentOS ver 6.3 server as Host OS. On top of it I have a Virtualbox on which Guest OS Windows 2012 VM has been running. I want to set up a single sign-in in a way in which I sign-in to Windows Server using terminal clients (Ncomputing L300) but data of each user should be stored on CentOS host directories and not within VM.

I am able to join the domain on Windows 2012, I am able to do single sign on when I create user in Windows AD. User also gets access to Host OS (CentOS) shared folder but I am facing following problems:

1) Everyday when server starts in morning, I need to rejoin the domain with command:

"net join ads -U Administrator -S name.domain.extention"

it prompts for password and if given it joins the domain successfully and I need to restart the winbind services with command

"service winbind restart"

I want to get rid of these command entering routine.

2) The users I create can login to Windows 2012 AD, but their home directory is not getting created automatically in CentOS host, unless I first physically sign on directly on CentOS.

I want the folders to be created automatically as we create default user folder path in Windows Server.


3) My folders like Desktop, My Documents, Favourites, Profile (folder redirection for roaming profiles) are not getting redirected on user's shared folder on CentOS host.

I need the folder to automatically reside on CentOS host directory specified.


I am attaching smb.conf, krb5.conf, hosts files.


Need urgent help. I am not a Linux Pro / Expert so please pardon my naivety. Thank you in advance.

Ok, so write a script to perform these steps, and have it run after the system is booted. A brief look at the CentOS documentation tells you how to do this:
https://www.centos.org/docs/5/html/I...-run-boot.html

Put the command(s) in there.
So tell the system to create the directories. A look at the documentation leads you to:
There are also other things/programs you can check:
http://www.dalemacartney.com/2012/07...ries-in-linux/
But start with the AD configuration on the Linux system. There are options to create the users home directories, and unless you enable them, it won't work.
...because you don't have the folders/home directory created, so there's no where for them to go.
Please see the posting guidelines...this is a volunteer forum..NOTHING is 'urgent' here for ANYONE, and asking for/expecting 'urgent' help is fairly rude.
