One or more errors occurred while publishing Azure Cloud Service from Visual Studio

Recently, I was trying to publish my Azure Cloud Service from Visual Studio and was getting an error "One or more errors occurred".

I couldn't find any more details in the Output window and was wondering what went wrong
Finally I looked at Server Explorer and it showed "Reneter your credentials".

After right clicking and re-entering the credentials, I was finally able to publish the cloud service.

AADSTS65001: No permission to access user information is configured for xxx' application, or it is expired or revoked

Recently, I had built an AAD application in my tenant with the permission “Enable single sign-on and read user’s profile”.

The application didn’t have admin consent so any time a user would login to my site, he would be asked for consent. I had some users who had consented to my app.

After some time, I added another permission “Access Azure Service Management” to my app and I was able to login fine. Users who had never consented to my app earlier could also sign in. However, users who had already consented to my app before I added the new permission started seeing this error “AADSTS65001: No permission to access user information is configured for xxx' application, or it is expired or revoked. “

I was really confused why the app works for some users but not for others.

After understanding the pattern that the error occurs only for users who had already consented, I asked them to perform the following work around:

1. Go to https://myapps.microsoft.com
2. Remove the app
3. Sign in again to the app in a fresh browser session
4. Now you will see the consent prompt for two permission
5. Grant consent   

After this, all users were able to login successfully.

FiddlerCore - ByPass Intranet Traffic

Found a nice trick to bypass intranet traffic while using fiddler core.

Comparing X509Certificate Subject with User Input

Recently I encountered an issue where I was comparing the certificate name of an X509Certificate with a user input.

The issue was that the subject a user would see on the certificate property has spaces in it

E.g. CN = xxx

However, when querying the subject of an X509Certificate2 object, it won’t have any spaces in it

E.g. CN=xxx

This would make the subject comparison fail

The fix was to use X500DistinguishedName for comparison of subject. Below is a snippet    

X509Certificate2 certificate = new X509Certificate2(@"xxx.cer");

// certificate.Subject results in CN=xxx

            X500DistinguishedName certificateSubjectname = new X500DistinguishedName(certificate.Subject);

            X500DistinguishedName configuredSubjectname = new X500DistinguishedName("CN = xxx");

            bool result = string.Equals(certificateSubjectname.Decode(X500DistinguishedNameFlags.None), configuredSubjectname.Decode(X500DistinguishedNameFlags.None), StringComparison.CurrentCulture);
