Qiang Zhang updated RANGER-1358:
--------------------------------
    Request participants:   (was: )
             Description: 
If the linux user dones not exist, the password is not set after the user is 
created during installing Ranger Policy Admin. The current logic is reasonable 
if the user exists during installing Ranger Policy Admin . Now we can only use 
the new linx user according to as following methods:
1. Set the new user password manually.
2. Login system using root user. Then use su command to switch the new user.
Obviously, these steps increase the difficulty of the user to use the system 
and reduce easy-using of the Ranger Policy Admin.

And the user group would be duplicate created if the user group existed during 
installing Ranger Policy Admin.

We should set password for the new user after the user was created. And We 
should check whether the user group exists during installing Ranger Policy Admin
