WebLogic Server and OpenLDAP. Using Dynamic groups

Dynamic groups in an LDAP are groups which contain a query to specify its members instead of specifying every member separately. Efficient usage of dynamic groups makes user maintenance a lot easier. Dynamic groups are implemented differently in different LDAP server implementations. Weblogic Server can be configured to use dynamic groups in order to fetch users for a specific group. In this blog I will describe how dynamic groups can be created in OpenLDAP and used in Weblogic Server.

In this example I use two users. smeetsm the developer and doej the operator. As shown in the image below, there are many servers which follow a similar access pattern for operators and developers. We are considering a case here where users do not use a shared account (e.g. weblogic) to login to different systems. This is for trace-ability and security purposes a better practice than when everyone uses the same shared user. See for a more thorough explanation on why you would want this.

A small note though. I'm a developer and this is not my main area of expertise. I have not implemented this specific pattern in any large scale organization.

Authentication using OpenLDAP. Weblogic Console and BPM Worklist

In this blog I will illustrate how you can configure Weblogic Server to use OpenLDAP as authentication provider and to allow OpenLDAP users to login to the Oracle BPM Worklist application. In a previous blog I have already shown how to do Weblogic Authentication with ApacheDS ( In this blog I will use OpenLDAP to also do BPM Worklist authentication.

Unleash the power of Java API's on your WLST scripts!

Oracle SOA Suite and many other Oracle products have extensive Java API's to expose their functionality. WLST can often be used for relatively course grained actions.  WLST (the version supplied in Weblogic 12.1.3) uses Jython 2.2.1. Jython is the Python scripting language implemented on the Java Virtual Machine. Jython allows easy integration with Java. In this article I describe how you can unleash the power of these Java API's on your WLST scripts!
