In this blog, we will show how to create a new user in openLDAP using Mule LDAP connector.
This flow has been tested against a Mac openLDAP server, using the core schema. Also we need to setup an LDAP tree like ou=people,dc=example,dc=com .
Here is the flow we are using,
- Receive create user request via HTTP GET request (only passing in dn, distinguished name)
- Look up dn from LDAP and return the lookup result
- If the lookup fails by a NameNoFoundException, the Exception flow is invoked
- A Java transform pulls out the dn and fills in a set of pre-defined user data (for demo purpose) and puts them in a map
- LDAP transformer transforms the map into an LDAPEntry
- LDAP connector is called to insert newly created LDAPEntry into LDAP
But first, we need to install LDAP connector by going to Mule Studio/Help/Install New Software. Select "MuleStudio Cloud Connectors Update Site" and search for "ldap". Check "LDAP Connector Mule Studio Extension" and proceed to install it.
Next we need to configure an LDAP global element, by clicking on Global Elements' "Add" button.
Search for "ldap" and select "LDAP" under "Cloud Connectors", and click "OK".
Fill in "Name", "Principal DN", "Password", and "URL", click OK.
Here is the picture of the Mule flow. The normal flow returns if the LDAP exists in the system. The exception flow is called when the lookup fails and the addition of LDAP user is executed.
Here is the Java code for the Java LDAP to Map transformer. This is for demo purpose so a lot of hard coded information is used,
To test this flow, enter the following URL,
http://localhost:8082/ldap?dn=cn=ldapUser,ou=people,dc=example,dc=com
This causes a new LDAP user to be created under ou=people,dc=example,dc=com.
We can verify this by looking at the Mule flow output,

Notice the NameNotFoundException block. This exception is handled by CatchExceptionStrategy and then the addition of LDAP is triggered.
Also we can verify this through a LDAP browser.
This is just an extremely simple example and hopefully one gets the ideas of how easy and powerful Mule is to integrate with LDAP with minimum efforts.
