Thanks to Lukas:
Step 0: Install freipa-client on ubuntu 14.04 and configure sudo
integration
root at ubuntu1404:/# ipa-client-install --no-ntp
root at ubuntu1404:/# echo "sudoers: files sss" >> /etc/nsswitch.conf
root at ubuntu1404:/# grep services /etc/sssd/sssd.conf
services = nss, pam
root at ubuntu1404:/# sed -i -e 's/\(services.*\)/\1, sudo/'
/etc/sssd/sssd.conf
root at ubuntu1404:/# grep services /etc/sssd/sssd.conf
services = nss, pam, sudo
Step 1: configure sudo rules for ordinary user
Please follow the instructions from FreeIPA documentation.
http://www.freeipa.org/docs/master/html-desktop/index.html#sudo
This step was skipped, becuase it was already done few months ago
Step 2: login to machine as ordinary user, which is allowed to use sudo.
$ su usersssd01
Password:
$ id
uid=325600011(usersssd01) gid=325600011(usersssd01)
groups=325600011(usersssd01),30011(biggroup1)
Step 3: run command
sudo -l
// this command should show you which commands can be executed as root
// with sudo
$ sudo -l
sudo: unable to resolve host ubuntu1404.example.test
[sudo] password for usersssd01:
Matching Defaults entries for usersssd01 on ubuntu1404:
env_reset, mail_badpass,
secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin
User usersssd01 may run the following commands on ubuntu1404:
(root) /usr/bin/less, /usr/bin/vim
Step 4: If there weren't any problems then user will be able to run
command.
sudo some_command_listed_in_step3
$ sudo /usr/bin/less /etc/shadow | wc -l
21
$ echo $?
0
$ sudo apt-get install mc
Sorry, user usersssd01 is not allowed to execute '/usr/bin/apt-get install
mc' as root on ubuntu.example.test.
$ echo $?
1

Dear All,
I am able to configure the sudo settings in Centos clients by
adding/modifying the entries in /etc/nsswitch.conf and
/etc/sudo-ldap.conf. What is the exact steps for the configuration in
Ubuntu as I am not able find the configuration file sudo-ldap.conf in
Ubuntu.
