If the JAAS framework needs to ask for a password (because you have no cached ticket), it asks the JDBC driver for the password, which the driver gets from the URL.SQL Store Procedure in IBM i is a CLE program so it can also be debugged as a simple CLE program. Note: You specify the password in the connection string. For additional information about the Krb5LoginModule settings, see Class Krb5LoginModule. The following example uses Krb5LoginModule. The available configuration settings depend on the LoginModule you specify in the configuration. The default JAAS configuration name for Vertica is verticajdbc. This file tells DbVisualizer to use Krb5LoginModule with the user principal vertuser. The following is a sample JAAS configuration file. The Vertica server you want to connect to must already be configured for Kerberos authentication.In the example in the blog post, we call this vertica.jaas. You have a valid JAAS configuration file.You have a valid Kerberos user principal that matches a user in Vertica database.Without this mapping, the Kerberos client does not know which KDC to request a service ticket for, given a Vertica service principal, which is typically specified by the -K argument in vsql.Ĭonsult the MIT Kerberos documentation for the appropriate settings. If that is not the case, for example, if that host is in the COMPANYCORP Kerberos realm, you need a domain_realm mapping like the following: O An appropriate mapping in the section, if the Vertica server’s realm cannot be discovered based on the server’s FQDN name using the client’s DNS settings.įor example, the domain realm is assumed to be in the VERTICA Kerberos realm. In particular, the following settings should be consistent between client and server: This is because the newer JVM 1.9++ can’t interpret the Linux style path. For example, in a Windows environment, if you are using JVM 1.9++, you will need to comment out “includedir /etc//” in the krb5.ini file. However, the client may require different settings if the network environment differs. Oftentimes, the nf from the Vertica server can be reused by the client. You have a nf file for the client that is consistent with the vertica server and the Key Distribution Center (KDC) you’re using.Copy the JDBC driver from /opt/vertica/java directory of any Vertica server node. The built-in JDBC driver that comes with the JDBC client might not be compatible with the Kerberos options for the Vertica server.
