We need an experienced programmer who is thoroughly familiar with the concepts of LDAP. The project is to make modifications to the authentication module of OpenLDAP. We need to redirect the authentication of user+password from LDAP to our own autehntication server. So, suppose we have a mail server which is authenticating via open LDAP. The idea is to make the OpenLDAP server redirect the authentication request to our server (via webservice call). Our server will then tell the OpenLDAP server if the credentials are correct or not. For all other purposes Open LDAP will work as usual.
Past work experience with Open LDAP ill be a huge parameter in contractor selection.
