1. Create a source policy module:
_________________________________

mkdir ~/myuser; cd ~/myuser;
echo "policy_module(myuser, 0.0.1)" > myuser.te;
echo "role myuser_r;" >> myuser.te;
echo "userdom_unpriv_user_template(myuser)" >> myuser.te;

2. Build the source policy module:
__________________________________

make -f /usr/share/selinux/devel/Makefile

3. Install the binary policy module:
____________________________________

sudo semodule -i myuser.pp

4. Create default contexts for myuser:
______________________________________

echo "system_r:local_login_t:s0       myuser_r:myuser_t:s0"
> /etc/selinux/targeted/contexts/users/myuser
echo "system_r:remote_login_t:s0      myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "system_r:sshd_t:s0              myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "system_r:crond_t:s0             myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "system_r:xdm_t:s0               myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "myuser_r:myuser_su_t:s0         myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "myuser_r:myuser_sudo_t:s0       myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "system_r:initrc_su_t:s0         myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser
echo "myuser_r:myuser_t:s0            myuser_r:myuser_t:s0"
>> /etc/selinux/targeted/contexts/users/myuser

5. Create a SELinux user mapping for myuser:
____________________________________________

sudo semanage user -a -L s0 -r s0-s0 -R "myuser_r" -P user myuser

6. Add new myuser user for prakash:
___________________________________

sudo useradd -Z myuser prakash
