Title: Project Overview


1
Project Overview
  • Single Sign On Solution
  • Robin Lilly

2
Description of Single Sign On
  • Single sign will allow user to sign on to UTEPs
    system one time and be logged into all the
    diverse systems from that one session.
  • Exchange Mail
  • DotNetNuke Portals
  • CAs CleverPath
  • GoldMine

3
Single Sign On Goals
  • Feasible
  • Scalable
  • Secure
  • Within budget
  • Immediate solution
  • Meets future needs
  • Independent of 3rd party systems

4
Some Problems Encountered
  • Dependence on CleverPath
  • Password to use in other systems was stored in
    CleverPath
  • Retrieval of Password will never be successful
    based on current API
  • Request Response objects
  • CleverPath XML API problems
  • No API to keep session alive when not in
    CleverPath
  • No successful creation of CleverPath Session
    without redirecting to CleverPath
  • No API ability to kill CleverPath session
  • Session Info is stored in CleverPath

5
Solution
  • Stores session/password information
  • Pass request response objects
  • Build independent solution

6
Look at some uses of Single Sign On
  • Sign On to System
  • Check if Im signed on

Validation
  • New technology being used
  • Benefits
  • Standards being adopted
  • Benefits
  • Standards specifically being ignored
  • Drawbacks benefits
  • DYA define your acronyms!

Classes
  • Talk about supporting classes
  • Registry
  • MyRegistry
  • Rijndael
  • SessionInfo

See Page 2 of SingleSignOn Document
11
Users Session Classes
  • UsersDB class wraps the UserSessionInfo table
  • UserCredentials class is passed the Session
    Salt at instantiation
  • It then makes a call to GetUserSession
  • It then decrypts the password with a call to
    Rijndael

12
UserAttributes Class
  • UserAttributesInit()
  • Get Session Info from the cookie (SSO Class)
  • Gets UserCredentials from Database
  • GetUserAttributes()
  • Call iPlanet XML for attributes

See Page 3 of SingleSignOn Document
13
Single Sign On Class
  • Constructors
  • IsActiveSession()
  • Get Cookie Info
  • Check Database if Session is valid
  • Check other systems active

See Page 4-6 of SingleSignOn Document
14
Single Sign On Class (cont.)
  • LogIn(UserID,Password),
  • Remove Old Session Cookies
  • Generate Salt
  • AuthenticateUser(UserID, Password)
  • Call CleverPath XML API to Create Session
  • Store Session in Cookie and Database

See Page 7-8 of SingleSignOn Document
15
Single Sign On Class (cont.)
  • LogOut()
  • Calls RemoveSession()
  • Calls RemoveCleverPathCookie()
  • RemoveSession()
  • Removes Cookie Database Entry
  • RemoveCleverPathCookie()
  • Removes CleverPath Cookie

See Page 9 of SingleSignOn Document
16
Single Sign On Class (cont.)
  • GetSessionInfo()
  • Get Session Cookie
  • Put SessionId and Salt into SessionInfo

See Page 10 of SingleSignOn Document
17
Single Sign On Class (cont.)
  • SetSessionCookie(SessionID,Salt)
  • Writes an in memory cookie with SessionID and
    Salt Out
  • SetCleverPathSessionStillActive(SessionID)
  • Changes CleverPath Cookie to still be active

See Page 11-12 of SingleSignOn Document
18
Single Sign On Class (cont.)
  • GetSignOnURL(RedirectPage)
  • Returns the URL of the signon page with the
    return page as the page passed in

See Page 13 of SingleSignOn Document
19
Things CA should do
  • Changes to CleverPath API or do our own fix
  • Is Session Active
  • Remove Session
  • Keep Session Active
  • Fix CleverPath to go to Logout Screen
  • Fix CleverPath to go to Logon Screen

20
Things we need to do
21
Conclusion
  • No significant under site on design
  • Control with UTEP not CA
  • Can grow with UTEP
  • Probably have some new classes
  • CASystem Class
  • GoldMineSystem Class
