Hey,

great read. We are just preparing to publish our CRM server via IFD to support outlook clients are are unsure about going the FBA or letting CRM do the authentication.

We currently have quite a strict 2 DMZ layout (one AD enabled, the other not) off the ISA but the CRM server is back at our head office (near the SQL server). My initial instincts are to let ISA do the FBA so that it can clean out any of the junk from "attacks" before allowing known good users through.

Do you think there is any kind of risk really to allowing the traffic through to the CRM box?

We were looking at potentially having a seperate URL for the external outlook client (with certificate authentication) to use and then let ISA do address rewriting on the traffic coming through.

Any thoughts about the above?

Thanks for your comment.

Since your environment has some custom requirements I recommend you to open an Advisory case with CRM Team so they can evaluate your request and advice thet best solution for your case.

Hey,

i have tried to add the publishing-rule to my ISA environment as shown above. At the moment there are 2 other rules for publishing Sharepoint and OWA through FBA existing. But when i do the settings above i must delete my existing Weblistener for OWA, etc.

I'm using a wildcard SSL- certifiacte.

In the past i have published CRM 4.0 also through FBA. In Version 3 of CRM i get no error and troubles. But since the upgrade to Version 4.0 i get some error's in CRM 4.0 like "error receiving the date", etc. when i open a item where a calendar/date-field is existing. That's my point why i try to publish CRM over the way you describe.

Any other suggestions how to get running ?

Hi Markus,

If to make it work you have to delete the current WebListener seems that you have a conflict. Also, it is not clear why kind of error you receive when you try to access the CRM publishing rule.

Follow the procedure below to run the ISA BPA on your ISA Server. The ISA BPA can help you to identify where the conflict is:

If you get stuck on that, please open a incident support with Microsoft CSS. Here it is the contact information for that:

Thank you.

Hi,

just wanted to report that we implemented an IFD scenario according to this guide. However, I did notice one thing when it comes to using the CRM outlook client with this solution. In our case, we had to configure the IFDTool to use HTTPS (from the drop down list visible in the picture above) for the IFD Domain Scheme.

If this was set to HTTP, the web client still works and uses SSL, but the CRM outlook client uses the CRM discovery service to find the address of the server, and if the option is set to HTTP the service returns a non SSL address to the client. If subsequently the ISA server is set to allow SSL only, this means that the configuration wizard for the outlook client will throw a "Server not found" error. Setting this option to HTTPS (or allowing non-ssl traffic through ISA) solves the problem.

CRM form based authenticatoin page is not showing

Hi,

Can you shed some more light on my 2 questions please?

1. I have setup the CRM IFD, published via ISA server 2006 by following your article. However, when user logs on externally to CRM, they don't have the form based authentication page, instead they got the Windows login prompt. I suspect CRM is treating external users as internal users, hence not showing the signin.aspx page.

When I tried to access the https://crm.domainname.com/signin.aspx, I don't get anything. IE simply told me the destination cannot be reached.

What would be the likely issue here? Is it mainly to do with how CRM determine if you can coming from outside?

2. When you say about the external URL needs to be resolvable from inside the network. Do you mean internal computers should be able to query the external URL and expect the internal IP address of CRM server will be returned? e.g. if my external URL is crm.domain.com, and my CRM server is 10.0.0.1 Should crm.domain.com be resolved into 10.0.0.1 on the inside of network?

Thanks!

Johnmen,

I have the same problem with the CRM form. I changed the ISA configuration to use FBA on the ISA listener and NTLM authentication on the ISA rule and that is working.
