RSA ISA 2006 Exchange 07 CAS Configuration Part III

Filed under: General — telnet25 @ 8:15 pm

Now it is time to jump on ISA server and make the configurations to make RSA work. lets start with backing up ISA configurations in case (-:, things go well and we need to roll back the changes.

Log into ISA server Open ISA Console we will backup entire ISA configuration as well as one rule which we will make the changed on , click on Arrays, server right click Export (backup)










we can accomplish same for single rule


Now the first rule I have is existing OWA Rule , you can disable this rule create another one delete if you wish or modify it all these will work, I prefer modifying existing one…

right click on the existing rule go to properties




Click Properties once more and place check mark on

  • HTML form Authentication
  • RSA SecureID


Click on 

  • Authentication delegation
  • Basic authentication



  • Click okay to get out, log into CAS server
  • Server configuration
  • Client access
  • open properties Exchange ( default Web Site)
  • click Authentication and set it to (Basic authentication , password is sent in clear text)


click okay and issue

  • iisreset /noforce


Now if you open your webmail URL you will see similar window to below



  • Username: Your username
  • Passcode: Your 6 pin secret + 6 Pin RSA Generated Code
  • If your 6 Pin Code is 123456 and RSA token is showing XXXYYY
  • Passcode:123456XXXYYY
  • Password: Your Password

you will see your e-mails after successful login to OWA with two ways authentication…
