Integrating Struts2 and spring security -with apache ds


Pre-requisites:
  1.      Apache directory studio-1.5.3
  2.        Apache- Ds server 1.5
  3.      Jboss5.1ga
  4.       Eclipse
  5.    Java 1.6

Add  a application-security-ldap.xml to web-inf folder.

The application-secuirty-ldap.xml file  contains 2 parts  that needs to be configured: http and the authentication manager

The http tag-contains url that needs to be authenticated and  and authorised with role.
If a user is authenticated and not authorised -then the app redirects the user to access denied page.This configuration is done in web.xml file.


The second part is the <authentication-manager> this has information about type of authentication provider used, its urls and credentials.In the below example I have used ldap-server which connects with apache ds which is listening at port:10389 and the partition that needs to be searched is "sevenSeas".
The ldap-authentication provider gives input on what attributes needs to be searched for the user name.In the configuration- mail is mapped as username  and roles are retrieved from groups the role names are then prefixed with  ROLE_
