Hue uses search bind authentication by default. To enable direct bind authentication, set the search_bind_authentication property to false in the /etc/hue/conf/hue.ini file:

# Do not use search bind authentication.
search_bind_authentication=false

When you set search bind authentication and you also need to set the kind of subgrouping and referrals for users and groups in the /etc/hue/conf/hue.ini file:

# Choose which kind of subgrouping to use: nested or suboordinate(deprecated).  
subgroups=suboordinate

# Define the number of levels to search for nested members.
nested_members_search_depth=10

# Whether or not to follow referrals
follow_referrals=false
