Re: [saml-dev] SAML and Siteminder question
Nathan;

SAML is used for SSO across domains.
 Since you are within the same domain you don't need to use SAML protocol.
 

If you are using siteminder the only
way to decrypt their cookie is either through their agent or some API call.
 ColdFusion is a different web/app server and won't know how to do
anything with that cookie.  Your application will always present the
user a login page unless your CF server has either an agent or makes an
API call to decrypt the cookie.  I use a 'similar product' and the
cookie created by siteminder will be decrypted by their proprietary decryption
algorithm -- which I don't think is available as open source.

Cheers,

Irfan

[saml-dev] SAML and Siteminder
question

Hello All,

Disclaimer: I'm a newbie at all of this so please forgive me if I use

the wrong language or don't describe things well.  Also, I'm not sure

if this is the right place to post this... right now I just don't know

where else to turn.

Short Summary:

My university uses Siteminder for their Single Sign-On solution.  I

built a webapp for the university, and now the university IT people

are telling me it is going to cost $8,000 to install an agent on the

machine so that it will meet the SSO guidelines.

I don't have $8,000 and I was wondering if there was a open

source/free way to get SSO to work.

Long Story:

Brigham Young University, BYU, has an intranet called "Route Y".

Students login with their username and password, they get some cookies

(including a SMSESSION cookie), and then they are on the protected

part of the site.

Well, the portal of the protected part of the site contains a bunch of

links, and the IT people would like to include the Bookexchange that I

wrote in the list of links.

However, the bookexchange is running on a different server, and the IT

people said that in order to get the link, it needs to follow the SSO

requirements.  They then told me it would cost $8,000 to have an

engineer come over and install an agent on the machine.

I told them I didn't have that money.  They told me that if I could

figure out how to decrypt the SMSESSION cookie on my own then that

would be fine.  You see, the bookexchange is running within the same

domain as route y, and I have access to the SMSESSION cookie.  But
I

don't know how to decrypt it (I'm using ColdFusion).

I searched google, "decrypt siteminder cookie" and I stumbled
across

SAML.  However, my brain hurts and I'm having a tough time wrapping
my

arms around all of this.

Is it possible to use SAML to get SSO to work with Siteminder?  Is

there anyone that has implemented something like this?  Is there a

"HOWTO" document somewhere?  (My problem right now is that
I'm not a

siteminder expert or a SAML expert, so the documents I do read don't

make much sense to me because they assume I know about siteminder

and/or saml).

THanks!
