Kyuubi can be configured to enable frontend LDAP authentication for clients, such as the BeeLine, or the JDBC and ODBC drivers. At present, only simple LDAP authentication mechanism involving username and password is supported. The client sends a username and password to the Kyuubi server, and the Kyuubi server validates these credentials using an external LDAP service.

Enable LDAP Authentication

To enable LDAP authentication for Kyuubi, LDAP-related configurations is required to be configured in $KYUUBI_HOME/conf/kyuubi-defaults.conf on each node where Kyuubi server is installed.

For example,

```properties example kyuubi.authentication=LDAP kyuubi.authentication.ldap.baseDN=dc=org kyuubi.authentication.ldap.domain=apache.org kyuubi.authentication.ldap.binddn=uid=kyuubi,OU=Users,DC=apache,DC=org kyuubi.authentication.ldap.bindpw=kyuubi123123 kyuubi.authentication.ldap.url=ldap://hostname.com:389/

  2. ## User and Group Filter in LDAP
  4. Kyuubi also supports complex LDAP cases as [Apache Hive](https://cwiki.apache.org/confluence/display/Hive/User+and+Group+Filter+Support+with+LDAP+Atn+Provider+in+HiveServer2#UserandGroupFilterSupportwithLDAPAtnProviderinHiveServer2-UserandGroupFilterSupportwithLDAP) does.
  6. For example,
  8. ```properties example
  9. # Group Membership
  10. kyuubi.authentication.ldap.groupClassKey=groupOfNames
  11. kyuubi.authentication.ldap.groupDNPattern=CN=%s,OU=Groups,DC=apache,DC=org
  12. kyuubi.authentication.ldap.groupFilter=group1,group2
  13. kyuubi.authentication.ldap.groupMembershipKey=memberUid
  14. # User Search List
  15. kyuubi.authentication.ldap.userDNPattern=CN=%s,CN=Users,DC=apache,DC=org
  16. kyuubi.authentication.ldap.userFilter=hive-admin,hive,hive-test,hive-user
  17. # Custom Query
  18. kyuubi.authentication.ldap.customLDAPQuery=(&(objectClass=group)(objectClass=top)(instanceType=4)(cn=Domain*)), (&(objectClass=person)(|(sAMAccountName=admin)(|(memberOf=CN=Domain Admins,CN=Users,DC=domain,DC=com)(memberOf=CN=Administrators,CN=Builtin,DC=domain,DC=com))))

Please refer to Settings for LDAP authentication in Kyuubi for all configurations.
