If using access_provider = ldap, this option is mandatory. It specifies an LDAP search filter criteria that must be met for the user to be granted access on this host. If access_provider = ldap and this option is not set, it will result in all users being denied access. Use access_provider = allow to change this default behaviour.

If Kerberos authentication is used, authentication is supported between the Thrift client and HiveServer2, and between HiveServer2 and secure HDFS.
