I'm developing a web application with a web service. One of the requisites is to authenticate against an OpenLDAP server. The password in the OpenLDAP service are stored in ssha512 (Salted SHA512). My problem is that I need the salt to hash the password in order to authenticate. I know that the halt is in the base64 String in LDAP and i know how to retrieve it, but i want to send them from the Frontend to the Backend already hashed.
I have the following stadard schema:
WebApp -> WebService -> OpenLDAP
And i want to send the password from the WebApp (Frontend) login page to the WebService already hashed.
Is there any tip in how to achieve this? I'm using C# .Net and html + jquery and ajax.
Sorry for the bad English. Thanks for the help!
