How to set hdfs authorization with hue users

[#1]

I have imported some ldap users to hue and am willing to set up authorizon on hdfs with these ldap users.

For example, I have a user "Bill" in group "a_department" in hue, and I want to set a directory /data/a that can only be visited by all users belonging to group "a_department". 

I have tried to setup a hdfs group and import the user into this group, but I want a easy way to connect the hue user system with hdfs user system. 

How can I do it?

Thanks !
