Classes in white are given by Apache Directory Server as extension points. The following UML class diagram depicts the structure of the little example. Implementing the class PasswordHashInterceptor In order to build it, simply check it out and type “mvn install”. If the value given by the client is already provided in hashed form, nothing happens, and the given value is stored in the directory without modificationĬurrently, the sources are checked in here The algorithm should be applied if new entries are created or existing entries are modified (hence modify and add operations will be intercepted)
To be more concrete: If a userpassword is set by an LDAP client in plain text, a message digest algorithm should be applied to the value, and the one-way encrypted value should be stored
#APACHE DIRECTORY STUDIO ADD CUSTOM ATTRIBUTE PASSWORD#
No user password should be stored in the directory in clear text. The following requirement should be fulfilled by an interceptor.
#APACHE DIRECTORY STUDIO ADD CUSTOM ATTRIBUTE HOW TO#
In order to demonstrate how to write an interceptor, here is a simple but realistic example. A mistakenly written interceptor may lead to a dis-functional or corrupt server. Interceptors are a powerful way to extend and modify the server behavior. You can therefore implement pre-, post-, around- invocation handler by how you place the statement. The flow control is returned when the next interceptor’s filter method returns. Interceptors should usually pass the control of current invocation to the next interceptor by calling an appropriate method on NextInterceptor. In order to illustrate this, here is the list of interceptors from the default server configuration of ApacheDS 2.0. The ApacheDS configuration contains a chain of filters performing several tasks.
What exactly is an interceptor?Īn interceptor filters method calls performed on on the DefaultPartitionNexus just like Servlet filters do. It contains a simple example as a starting point. The following is for developers who plan to implement their own interceptors in order to extend or modify the functionality of Apache Directory Server. That’s it ! I hope this post is helpful.6 - Implementing a simple custom Interceptor for ApacheDS cn=config/cn/schema/ and edit the file cn=nsaproject,cn=schema,cn=config #yeah :-) This will create in place a directory called cn=config and a file cn=config.ldif. schema file with this command slaptest -f nf -F. cd touch echo "include /etc/ldap/schema/nsaProject.schema" > nf To begin, create a dummy file into /tmp/ldapworkingdir called nf for example and write into it the include directive to the nsaProject.schema. schema into an LDIF file and add it to OpenLDAP. I will not explain in detail the content of nsaProject.schema because it is out of the scope for this post. Now, create the file nsaProject.schema which contains the definition of the new and custom attributes and the new objectClass nsaEngineer and save it in /etc/ldap/schema/. Let’s start by creating a working directory for example /tmp/ldapworkingdir. schema format is simple to understand and to write for the beginners. Note : for more information about LDAP structures, please consult the following link : LDAP structure Creation of classic. Now, let’s go to create this schema (and objectClass and attributes). Now, the objectClass nsaEngineer has 3 customs mandatory attributes and a optional (description) which is referenced in another base schema. An objectClass contains references to other objectClass and attributes. As a reminder, a schema is a container (package) for one or many objectClass. This new objectClass has the name of nsaEngineer and the schema nsaProject.

For your information, my OpenLDAP runs on a Ubuntu Server 12.04 LTS with a 3.5.0-48 64 bits kernel. I suppose you already have a OpenLDAP server running. The best way to explain how to add new schema with 2.4 (and higher) release is to start with a real and practical example. schema (stored under /etc/ldap/schema/) were included into nf.
We can look that schemas must be placed as child of cn=schema,cn=config. The configuration in OpenLDAP 2.4 and next versions is now in LDIF format and it follows a pretty logical schema like this : I have read a lot of posts but honestly, I never find a good “how-to” which respond to the question in this post’s title.
I’m not an LDAP expert but I’m writing this article because I insulted my OpenLDAP and my Linux several times during one week while I try to add my own schema into OpenLDAP 2.4. Why ? Because since release 2.4, the structure of the server has a little changed. Hello ! In this post, I will explain how to add a new schema into OpenLDAP 2.4 and higher.
