Using CRM 2011 SOAP and REST endpoints with Silverlight
To communicate with CRM 2011 from Silverlight application you can either use SOAP or REST endpoints.
URL’s for both endpoints will be available under “Developer Resources” section (Go to Settings -> Customizations -> Developer Resources)
SOAP and REST endpoints
Below are the important points on usage & limitations of both endpoints
Using REST endpoint with Silverlight
- CRM 2011 uses the WCF Data Services framework to provide an OData endpoint that is a REST-based data service.
- This endpoint is called the Organization Data Service
- It supports early bound entity types so that the coding will be easy (i.e., you can instantiate contact c=new contact(); c.name=”Rajeev”)
- Limitations
- Only Create, Retrieve, Update, and Delete actions can be performed on entity records
- You need to regenerate the proxy every time you change the entity schema (Ex – If you create a new entity or attribute)
- You cannot use late binding to work with custom entities that were not included when proxy generated.
- Here is the MSDN article Walkthrough REST in Silverlight
Using SOAP endpoint with Silverlight
- Unlike the REST endpoint, the SOAP endpoint uses the Organization service
- You can do all the operations with SOAP endpoint
- Here is the MSDN article Walkthrough SOAP in Silverlight
- SOAP does not provide early bound entity types natively but here is article to how to use early bindings with SOAP

Access denied to temporary Asp.net files folder – error while browsing Aspx page
I was getting below “Access denied” error, when I was browsing my Aspx page hosted in IIS 7.
Access denied temp Asp.net files
Hers are more details about my hosted Asp.net web application
- Website application pool’s Pipeline mode is “Integrated”
- Application pool Identity set to a Service Account
Below is the reason and fix that worked in my case
Reason
- Issue seems a permission issue to access the temporary folder, for the account under which the website is running.
- In our scenario, it’s the “Service Account” under which website is running does not have write access to Temp folder
Fix 1
- Provide “Write” access to the “C:\Windows\Temp” folder, to the Account under which your application running
Fix 2
- Grant the required permissions to the “Service Account” by running Aspnet_regiis.exe -ga [User id]
- So it grants the specified user or group access to the IIS metabase and other directories that are used by ASP.NET.
- We typically use this option when creating a custom service account.

AD Groups created with CRM 2011 installation
With CRM installation below Active Directory (AD) Groups get created in the Organization Unit (OU) you chosen.
Below is the description of 4 AD Groups
|
AD Name |
Description |
| SQLAccessGroup | The members of this group get access to CRM filtered views |
| PrivUserGroup | CRM user group for special administrative functions; Including CRMAppPool identity (domain user or NetworkService). The users who configure CRM must be added to this group. |
| PrivReportingGroup | This group create during CRM Server Setup and configured during CRM Reporting Extensions Setup. |
| ReportingGroup | All CRM users are included in this group.This group is updated automatically as users are added and removed from CRM. By default, all CRM Reporting Services reports grant Browse permission to this group. |
These groups specific to the Organization. So a new set of groups get created when you create a new Organization.
If you have multiple Organizations each group will be suffixed by Organization GUID.

The user authentication passed to the platform is not valid error – CRM 2011
We were getting below exception when we click “Track in CRM” button from CRM 2011 outlook client
The user authentication passed to the platform is not valid
User Authentication Invalid
Fix
We fixed the issue by providing the “Act on Behalf of Another User” privilege to the User’s security role
Act on Behalf of Another User
So what is this privilege “Act on Behalf of Another User”?
- This privilege defines whether the user can impersonate another user.
- For example, you might want the system administrator to impersonate another user to act on behalf of the other user when doing some operations.
- Impersonation is only possible using the SDK and plugins, not in the application.
Another scenario
- You would get the same exception when you try to login to CRM with specific users.
- The reason could be your CRM user’s AD account is either deleted or re-created with different domain name.
