  2. Authentication • Objectives • Allow an application to authenticate an user by means of FEUPnet'sservices. • Protect FEUPnet

  3. Authentication • Research • One-Time Password - password that is valid for only one login session. • One of the purposes of project is to use SiFEUP credentials ( “static” credentials ) • Doesn’t apply.

  4. Authentication • Research • OAuth (Single Sign-on) - Very popular and reliable. Facebook, Twitter, Google andseveralotherapplications use thisprotocol. • Allows users to share their private resources stored on one site with another site. It allows to login in several applications using only one site credentials. It seems a good solution but… • This assignment is proposed to be used inside FEUP. • Sharing sensible resources stored in FEUP servers its not a good idea. • Implies implementing an OAuth server (need CICA authorization)

  5. Authentication • Research • LDAP - is an application protocol for accessing and maintaining distributed directory information. • CICA provides an LDAP server that can be used by students. • By default, authentication it’s not mandatory to obtain the information stored in the server. • However, there’s a way to force the user to insert their credentials. • The LDAP API references an LDAP object by its distinguished name (DN) and with the exact DN for an object the information is only presented after the correct credentials are inserted.

  6. Authentication • TestingtheLDAP server • The presented data it’s the same with or without authentication, however, it’s possible to guarantee the authenticity of the user and that’s exactly the propose. • We notice that, without the correct DN, with any password (the correct one or not) the security system fails. So.. • It’s crucial to obtain the correct DN, throughthe student identification number, before prompt for the credentials. • After that, it’s possible to guarantee the authenticity and another important aspect is that FEUP LDAP server provides MD5 method to authenticate.

  7. Authentication • Future Planning • The presented tests were made with the ldapsearch command present in linux systems. • The objective is to implement a script written in PHP that can be used by any web application implemented inside FEUP. That way, the application can authenticate a user without direct acess to central database. • Besides the principal problem of authentication, we want to implement the possibility of, after correct login, the return some information (name, identification number, course,etc) about the user. This can be used by application for filling out forms, by instance.
