The user or administrator has not consented to use Azure Analysis Service Client

Happy today because spent too much time to find out the issue happened in our Azure Tenant. The issue is very simple but took more time to reach the location.

Our development team have registered a AAD app for automatic refresh of Azure Analysis Service model using Azure Function Apps
The App Registered successfully in AAD and added Azure Analysis Services API Read&Write All model permission (It is bit confusing as the permission text is  Read&Write All Models)
The function App was not refreshing the model as expected.
Then  in addition the AAD App url is updated as “https:// northeurope.asazure.windows.net” (Does anybody think any thing wrong here) by development team.
Suddenly all Azure Analysis Service authentication got broke in our tenant including production services.  Unfortunately this incident happened in a long weekend(4days off 😝)
A support ticket raised with Microsoft and Azure support team asked us to delete the newly registered AAD App, then all service got started working.
As expected a huge escalation by customer, all appreciation got in the past is wiped off.
Unfortunately our team did not get  a chance to interact with Microsoft Support team and no error details shared.

My Involvement:
I am beginner in Azure but a bit curios to analyze what went wrong and took the responsibility but did not aware of the  pain at that time.
Spent around a week time, created multiple scenarios and different combinations but finally ends with nothing. The error was not reproduced.
Posted in Microsoft technical forum, but public contributors replied “I am wrong” , “We will not address the resolved issue”
Then again digged futher and got  clue from developer that  AAD APP url is updated  as “https:// northeurope.asazure.windows.net”
Then narrowed the investigation towards that direction

Registered a new app in AAD
Added Azure Analysis Services API Read&Write All Model  permissions
Updated the AAD URL as “https:// northeurope.asazure.windows.net”
Prepared following PowerShell Script

Install-Module -Name Azure.AnalysisServices
Install-Module -Name SqlServer
$UserCredential = Get-Credential
Login-AzureRmAccount -Credential $UserCredential
$Rolloutenv = "northeurope.asazure.windows.net"
Add-AzureAnalysisServicesAccount -RolloutEnvironment $Rolloutenv -Credential $UserCredential

Tried connecting to Azure Analysis Services using common resource name as specified in the script
Got following error

Add-AzureAnalysisServicesAccount : AADSTS65001: The user or administrator has n
ot consented to use the application with ID 'cf710c6e-dfcc-4fa8-a093-d47294e44c

    + CategoryInfo          : CloseError: (:) [Add-AzureAnalysisServicesAccoun
   t], AdalServiceException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.AnalysisServices.Datapl

Understood that the AAD App Url wan the culprit which has stopped all authentication of Azure Analysis Services
When I checked the GUID in internet I got below post where GUID used a resource in the source code.


The I was able to relate the GUID and Error massage.

Admin consent error thrown when accessing Azure Analysis services by any application or source code in our tenant.
o Application requested for Azure Analysis Service Access in AAD
o ADD found a AAD APP with “https:// northeurope.asazure.windows.net” as application url.
o AAD redirect the request to AAD app created by development team
o But the AAD App was neither actually requested resource nor Azure Analysis Service API Read & Write All model permission consented
o As a response from AAD, “application is not consented”

AAD is common  instance for a tenant. All development, QA and Production resources registered and maintained in same AAD.
So when we register a AAD app, we have to be more conscious and aware for consequences before giving permission to it.
Do not update AAD App url with any resource URL because it will create a huge impact.
Microsoft need to apply a additional validation on AAD app Url that “Common resource Url should not be allowed”

Access SharePoint online documents using Microsoft Graph API


Microsoft Graph API is one of the great feature which allows to access most of Office 365 services/objects from single endpoint. Recently I was asked to check the possibilities of accessing SharePoint Document libraries using Microsoft Graph API.

Well it is possible, find below the procedures used for accessing the document libraries.

https://graph.microsoft.com/v1.0/sites/{domain name}:/{named space}/{site collection name}:/drives


kmsys2.sharepoint.com: is my SharePoint online domain
accounts: is my SharePoint online site collection
drives: is signature for SharePoint document libraries

How to get context token of O365 in On-Prem web applications

Spent lot of time to get O365 context token in our on-prem SharePoint site to access SharePoint online content using single sign-on.

I would like to bring the situation in front before explaining the implementations. One of our customer has SharePoint On-Prem environment and O365 including SharePoint online and one drive for business. They recently configured O365 Cloud Hybrid Search, and plan to replace SharePoint Enterprise search using O365 Cloud Hybrid Search. We have got all information.

But when user search for any content from SharePoint on-prem site, it redirect to O365 login page then get the domain user name, then using ADFS for authentication  finally landing at the search result page of O365.

All three redirection is taking almost 10-20 seconds to reach search result page. This will happen when user accessing SharePoint Online site/office components very first time. Once it is accessed then the browser hold the context token then using the same for next O365 content access in the day.

We have tried many approaches to get O365 context token but finally failed because if we use custom C# code then need to pass the credential (user name and password) which is not aligned for single sign on, not able to use domain libraries also below approaches and ends with CORS issue.

1. Loading an profile image from O365 to on-prem page - failed
2. used CSS to call O365 image - failed
3. Used javascript variables to access O365 pages - failed.
4. Used iframe to access O365 portal -failed.

Spent enough amount of time finally got a breakthrough using iframe only but accessing different page.

Microsoft said that SharePoint sites page from O365 is accessible in iframe. We have tried accessing SharePoint page from html and SharePoint pages and found that it has created a context token. 

< iframe src="https://login.microsoftonline.com/login.srf?wa=wsignin1.0&whr=kmstechs.com&wreply=https%3A%2F%2Fkmstechs.sharepoint.com%2F_layouts%2F15%2Fsharepoint.aspx" style="visibility:hidden" > </iframe >

1. Added a hidden content editor web part and place below iframe tag to create context token in the page.
2. The context token will be created whenever the site is loaded thereafter if user searches for any content then the request used already generated context token redirecting directly to O365 search result page.

Happy working with SharePoint :-)

Export and Import SharePoint List with content using PowerShell

We had SharePoint farms in many variation SharePoint 2007, SharePoint 2010 and SharePoint 2013. Recently I had worked on a assignment that migrating single list data from SharePoint 2007 to SharePoint 2010.  Initially I thought that it bit easy task but when get in to it, it had given many issue because I was told that there should not be any change in the data including modified date, modified by, created data, created by finally all versions as it is.

I was in trouble because the source list is 100% customized(custom fields, custom content types, list definition, event receivers and New, Edit & display forms as well)

I had upgraded the custom functionality to SharePoint 2010 excluding custom input forms. But export import command, failed all the time.

Ends with lot off issue like, fields are duplicated, content type is not matching, field ids are not matching, destination web, list are are not available and so many.

Thought of implementing some data correcting before importing the SharePoint 2007 list content.

1. I had trimmed the custom source code only with Custom fields and Custom Content Types
2. Deployed the latest build on SharePoint 2010 farm
3. Created a new list and added custom content type, Enabled versioning and removed default content type "Item".
4. Created a test item using new custom content type
5. Exported the SharePoint 2010 list as.DAT file
6. Renamed .DAT to .CAB and extracted all files in to new folder
7. Exported SharePoint 2007 list as .DAT file
8. Renamed .DAT to .CAB and Extracted all files in to new folder
9. Opened the manifest.xml file from SharePoint 2007 extracted folder and copied SPListItem elements
10. Opened the manifest.xml file from SharePoint 2010 extracted folder and pasted Copied SPListItem elements.
11. Replaced the below ids on newly pasted element
      ParentId, ParentWebId, FileUrl,URL,ContentTypeId,
12.Created .CAB files form extracted SharePoint 2010 files.(used makecab.exe)
13. Imported the cab to SharePoint 2010
14. Verified the list
15. All worked fine.

Blow are the PowerShell scripts I used for migration.
