Active Directory Settings

This section provides additional information about Shiro Active Directory settings.

Active Directory (AD) stores users and groups in a hierarchical tree structure, built from containers including the organizational unit (ou), organization (o), and domain controller (dc). The path to each entry is a Distinguished Name (DN) that uniquely identifies a user or group.

User and group names typically have attributes such as a common name (cn) or unique ID (uid).

Specify the DN as a string, for example cn=admin,dc=example,dc=com. White space is ignored.


If you upgrade from HDP 2.5 (Zeppelin 0.6) to HDP 2.6 (Zeppelin 0.7), note that the Active Directory group realm class name changed from org.apache.zeppelin.server.ActiveDirectoryGroupRealm to org.apache.zeppelin.realm.ActiveDirectoryGroupRealm in Zeppelin 0.7. For information about changing this setting manually, see "Configuring and Upgrading Apache Zeppelin" in the HDP Command Line Upgrade guide.


specifies the class name to use for AD authentication. You should set this to org.apache.zeppelin.realm.ActiveDirectoryGroupRealm.


specifies the host and port where Active Directory is set up. .

If the protocol element is specified as ldap, SSL is not used. If the protocol is specified as ldaps, access is over SSL.

Note: If Active Directory uses a self-signed certificate, import the certificate into the truststore of the JVM running Zeppelin; for example:

echo -n | openssl s_client –connect | \
    sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/examplecert.crt

keytool –import \
    -keystore $JAVA_HOME/jre/lib/security/cacerts \
    -storepass changeit \
    -noprompt \
    -alias mycert \
    -file /tmp/examplecert.crt

simplifies the logon information that users must use to log in. Otherwise, AD requires a username fully qualified with domain information. For example, if a fully-qualified user account is, you can specify a shorter suffix such as user@hdpqa.

activeDirectoryRealm.principalSuffix = @<user-org-level-domain>

defines the base distinguished name from which the directory search starts. A distinguished name defines each entry; "dc" entries define a hierarchical directory tree.


defines the username and password that Zeppelin uses to connect to Active Directory when it searches for users and groups. These two settings are used for controlling access to UI features, not for authentication. The Bind method does not require a valid user password.

Example: activeDirectoryRealm.systemPassword = passwordA


a comma-separated list that maps groups to roles. These settings are used by Zeppelin to restrict UI features to specific AD groups. The following example maps group hdpdv_admin at to the "admin" role:


specifies whether to use caching to improve performance. To enable caching, set this property to true.
