Hi,

Please let me know how to pass username as a parameter to the ISA server.

My system setup:
I have a web interface [custom built proxy] in front of an ISA 2006 server that prompt users to enter their username and a memorable word. If the user has entered the correct memorable word, the custom proxy re-directs users to ISA servers.

The default ISA server page prompt users for username/password and validate based on their AD account. If validated users will be re-directed to a SharePoint 2010 site.

I want the username to be passed into the ISA server from my custom proxy so that the users will not have to re-enter the username. User will only need to type in the password as the username is pre-populated.

Please let me know how to pass username as a parameter to the ISA server.


Regards
Chamila

Hi,

when you choose to use Integrated authentication on ISA. It transparently authenticates the user.

Hi Paulo,

Thank you for your reply.

In my setup I have a separate proxy server [Memorable Word Proxy] hosted before the  ISA server. External users will first come to the Memorable Word Proxy where they will be prompted to enter "UserName" and a "Memorable Word".

If the user has entered the correct word, the Memorable Word Proxy re-direct users to ISA. At ISA I want users to enter their AD password.

Since the application has already prompted for user name [at Memorable Word Proxy], users don't want to re-enter their user name at ISA propmt. I'm looking for a way to pass the UserName as a parameter to ISA login page.

Is this possible in ISA 2006 please?

Regards
Chamila

Hi Chamila,

I guess so. There´s one application that does what you want: http://www.collectivesoftware.com/Products/Captivate

You may gather more information on ISA SDK: http://technet.microsoft.com/en-gb/library/bb794717.aspx

Paulo Oliveira.

Captivate is actually not the right tool here, perhaps IsaScript though.

The first thing to figure out is, can you get the username into the redirect somehow, for example as a querystring parameter?

If the answer to this question is "yes", then I find it likely that we could build a script to populate this into the ISA FBA.  For something this simple, our support could create the script for you as a free support included with the purchase price.

But remember, you first need to get the username to be emitted from your custom proxy to ISA somehow.

Hi Ferrix,

Thanks, yes I can send the user name as a query string parameter.
When do you think an updated version of ISA FBA will be availale with this fix please?

In the meantime, is there any jscript fix I can use please to capture username from the querystring?

Regards
Chamila
