How to authenticate ldap user and login on server as GUI ,it should login on server directly via GUI - authentication

Question

I am new to System admin My problem is : In my department there are 30 students in 1st year and 30 students in 2nd year which are divided into two groups lets say group1 and group2 which need to login as ldap user via Ubuntu(14.04) GUI through any System connected to LAN.Every users home directory should be created on server side ,It should mount while login as GUI in ubuntu14.04, No other user should access anyone else home directory except by self.
[I don't want authenticating user to ldap-server and creating home directory on local machine ,instead I want central directory on server side,It should looks like login to server.]
Server Side : Ubuntu 14.04
I tried this and it works fine for me.
Client side : Ubuntu14.04
I tried this , it also works
but the issue is , this tutorial creates home directory on local machine instead of mounting server directory.I know from where it does.
I want : If i login through ldap user It should login on server via GUI not on local machine home directory.
on client side file "/var/log/auth.log"

Answer 1

You need to install and configure autofs for this to work. autofs will automatically mount user's home directories on the client machine from an NFS server. I'm not sure about creating them on the server on the fly, but if it does work, you will likely need to enable the pam_mkhomedir module in the appropriate /etc/pam.d file(s), as described here

Answer 2

Yep! I tried and worked for me.
**Server Side :** Package require to install :
$ sudo apt-get install nfs-kernel-server
Updated in below file like this
abdulrahim#issc-ldap:/ldap/batch2016part2$ sudo vi /etc/exports
#/homes 198.1.10.*(fsid=0,rw,insecure,no_subtree_check,sync)
/ldap/batch2015part1/home 198.1.10.*(fsid=1,rw,insecure,no_subtree_check,sync)
/ldap/batch2015part2/home 198.1.10.*(fsid=2,rw,insecure,no_subtree_check,sync)
Exported as per below::::
abdulrahim#issc-ldap:/ldap/batch2016part2$ sudo exportfs -r
root#issc-ldap:/ldap/rnd# showmount -e 198.1.10.45
Export list for 198.1.10.45:
/ldap/batch2015part1/home
/ldap/batch2015part2/home
**On Client Side :** Package require to install :
$ sudo apt-get install nfs-kernel-client
NOW ON CLIENT SIDE mount,permission ,ownership::::::
$ sudo gedit /etc/fstab
#####below are partition mounted from server
198.1.10.45:/ldap/batch2015part1/home /ldap/batch2015part1/home nfs nfsvers=3,sync 0 3
198.1.10.45:/ldap/batch2015part2/home /ldap/batch2015part2/home nfs nfsvers=3,sync 0 4
### or like this below
198.1.10.45:/ldap/batch2015part1/home /ldap/batch2015part1/home nfs noauto,x-systemd.automount 0 3
198.1.10.45:/ldap/batch2015part2/home /ldap/batch2015part2/home nfs noauto,x-systemd.automount 0 4
Now mount all pertition from server side as per below : :::::
$ sudo mount -a
Check mounted partion by below commands
$ df -h
