I have configured cloudera hue as follows

Authentication Backend desktop.auth.backend.LdapBackend
LDAP URL - ldap://10.77.36.37
LDAP Username Pattern- uid=<username>,ou=Users,dc=persistent,dc=com
search_bind_authentication - true
LDAP Search Base - dc=persistent,dc=com
bind_dn - cn=Manager
user_name_attr- uid

is there anything missing in above configuration. ?
