Configure LDAP Authentication Between Hue and Hive

[beeswax]
  ...
  # Security mechanism of authentication none/GSSAPI/MAPR-SECURITY
  mechanism=LDAP

[beeswax]
  ...
 # Override the default desktop username and password of the hue user used for authentications with other services.
  # e.g. Used for LDAP/PAM pass-through authentication.
  auth_username=sampleuser
  auth_password=123456
  ...

Or configure the [desktop] section of the hue.ini to set the username and password for all services that require username/password authentication:

[desktop]
  ...
  # Default LDAP/PAM/.. username and password of the hue user used for authentications with other services.
  # Inactive if password is empty.
  # e.g. LDAP pass-through authentication for HiveServer2 or Impala. Apps can override them individually.
  auth_username=sampleuser
  auth_password=123456
