OrientDB Kerberos Client Examples

The Java API client is dependent on the KRB5_CONFIG and KRB5CCNAME environment variables being set. Alternatively, you can pass them to the Java program via -Dclient.krb5.config=… and -Dclient.krb5.ccname=…, respectively. You can also set them in your Java client program by calling System.setProperty("client.krb5.config", "…./krb5.conf").

If a keytab is preferred, the KRB5_CLIENT_KTNAME environment variable may be set with the path to the keytab. Alternatively, you may pass the keytab path as the system property client.krb5.ktname.

What enables the Kerberos client support is a system property called client.credentialinterceptor. This must be set with the full package name to the Kerberos credential interceptor, as such:

java -Dclient.credentialinterceptor=com.orientechnologies.orient.core.security.kerberos.OKerberosCredentialInterceptor


System.setProperty("client.credentialinterceptor", "com.orientechnologies.orient.core.security.kerberos.OKerberosCredentialInterceptor");

In either case, this system property must be set to enable the Java client Kerberos support.

To use the client, you must specify the principal in the username field. The password field may also specify the SPN to use to retrieve the service ticket, but if left as an empty string, then the SPN will be generated from the host portion of the URL as such: "OrientDB/" + host.

The principal must either exist as a server user or must exist as an OUser record in the database to be accessed.

Java API Examples

The following is an example of how to use the OServerAdmin interface to send commands directly to the server:

String url = "remote:server1.ad.somedomain.com:2424";
String pri = "OrientDBClient@AD.SOMEDOMAIN.COM";
String spn = "OrientDB/db1.somedomain.com";

OrientDB orientDB = new OrientDB(url, pri, spn, OrientDBConfig.defaultConfig());
orientDB.create("TestDB", ODatabaseType.PLOCAL);

The next example shows how to open an existing OrientDB database from the Java client API:

String url = "remote:server1.ad.somedomain.com:2424";
String pri = "OrientDBClient@AD.SOMEDOMAIN.COM";
String spn = "OrientDB/db1.somedomain.com";

OrientDB orientDB = new OrientDB(url, OrientDBConfig.defaultConfig());
ODatabaseSession db = orientDB.open("TestDB", pri, spn, ODatabaseType.PLOCAL);

JDBC Client

The JDBC client support is very similar to the native OrientDB Java client. Make sure the KRB5_CONFIG and KRB5CCNAME environment variables (or system properties) are set accordingly and then set the client.credentialinterceptor system property and specify the URL, principal, and SPN appropriately:

System.setProperty("client.credentialinterceptor", "com.orientechnologies.orient.core.security.kerberos.OKerberosCredentialInterceptor");

String url = "remote:server1.ad.somedomain.com:2424/TestDB";
String pri = "OrientDBClient@AD.SOMEDOMAIN.COM";
String spn = "OrientDB/db1.somedomain.com";


Properties info = new Properties();
info.put("user", pri);
info.put("password", spn);

Connection conn = (OrientJdbcConnection) DriverManager.getConnection(url, info);

Statement stmt = conn.createStatement();

ResultSet rs = stmt.executeQuery("select from MyClass");

OrientDB Console

To enable Kerberos in the OrientDB console, you'll need to modify the console.sh (or console.bat) script.

Simply add the credential interceptor system property to ORIENTDB_SETTINGS as such:


Here's an example of connecting to the previously used URL, principal, and SPN:

connect remote:server1.ad.somedomain.com:2424 OrientDBClient@AD.SOMEDOMAIN.COM OrientDB/db1.somedomain.com

Here's another example, this time creating a remote plocal database on remote server:

create database remote:server1.ad.somedomain.com:2424/NewDB OrientDBClient@AD.SOMEDOMAIN.COM OrientDB/db1.somedomain.com plocal

Lastly, this final example with the console shows connecting to the NewDB database that we just created:

connect remote:server1.ad.somedomain.com:2424/NewDB OrientDBClient@AD.SOMEDOMAIN.COM OrientDB/db1.somedomain.com
