Here I am using WSO2-IS-4.0.0 and Apache Directory Studio to browse it. (my last post explain Apache Directory Studio features)

[1] Start wso2 IS from wso2is-4.0.0\bin>wso2server.bat

[2] Open Apache Directory Studio

[3] Go to the connection click on add connections

[4] give name, port (10389) and host as below

[5] Then for the next post you will get a fill this

Bind user: uid=admin,ou=system
Bind password: 'admin'.

[6] Then we can browser LDAP of wso2 products (IS) in LDAP browser panel
