I am trying out the Azure AD-B2C. The user signup/sign in is fine when the MFA is turned off. But when I turn it on, and the user tries to sign in and provides the phone number, and requests a text message by clicking "send code", I get the Http 400 error: size of request headers is too long. Anybody else have this issue?
The error HTTP 400: Size of header request is too long generally happens because there's too many cookies.
Azure AD B2C's login goes through login.microsoftonline.com, as does almost every Microsoft service (O365, Azure, etc). So if you've got several accounts that you've signed in to across these services, you're accumulating cookies that will cause this problem.
Clearing the cookies should resolve this problem. If this is happening on a recurring basis, you should edit your question to include details about the request and cookies in order to best figure out what's bloating the request and how to reduce it.
Short answer: The file with the custom UI was not found by Microsoft login service. After getting shipped around it resulted in the error.
I had the same error with AAD B2C but "cookies" was not the problem. In my case I got the error while testing in the Azure B2C portal checking the policies and the custom UI pages. We use Azure Blob storage to hold custom login setup, its fast and it scales without our attention. The problem was found by using my test website using the B2C service. I put a stop/break on the Account controller's "public Task OnRemoteFailure(RemoteFailureContext context)" method. The debugger message gave me the full context of the error, an http 404 error and it gave the file name it was trying to find. Blob storage is case sensitive. The setup configuration used to configure B2C has camelCase names. The group who created the actual UI customization uses all lower case names. It took someone with access to all the assets to find the simple case name issue. Errors in distributed systems can be difficult.

I attempted to implement the custom policy to allow phone authentication while setting up Azure ADb2c for my application and tried to follow the instructions present here - https://learn.microsoft.com/en-us/azure/active-directory-b2c/phone-authentication
I completed the prerequisites and believe I have everything setup correctly, but when i try to run the custom policy B2C_1A_SignUpOrSignInWithPhone, I receive a message to my phone number (based out of india) with the verification code, but when I enter the verification code into the browser, i receive an HTTP 400 with too many requests and I'm not sure why. How do I ensure that this feature will be functional if I implement it into my application. Has anyone else faced this issue ? (tried incognito as well)
SOLVED:
Looks like the file "Phone_Email_Base.xml" needed to be edited to include the tenant name in the two and tags. This was not mentioned in the tutorial and therefore took a bit of time to figure out why. I will be forwarding this to microsoft so that they can fix in their documentation.
I've built an API-based integration with DocuSign (using their PHP SDK), and am now at the point of deploying to the production server. I have reconfigured everything with the production integration key, public/private key pair, user and account IDs, endpoint URL, etc. replacing the demo ones. The OAuth portion of the conversation is working fine, and I get a valid token back. When I then try to send an envelope, I hit a USER_LACKS_MEMBERSHIP error, and cannot figure out why. As far as I can see, everything about the API user is the same between the demo and production systems.
I've authorized the application and made sure that it's in the list of "Applications with Access to DocuSign".
I have enabled logging, but the only things that are showing up in there appear to be from my own navigation in the site, nothing related to the API calls at all.
Most of the documentation that I can find on this simply repeats the generic error text: "The UserID does not have a valid membership in this Account." If I go to the account admin and look at the list of users, the one I'm expecting is right there, with DS Admin permission; not sure what else might be done to give them "membership". One mentioned not using SendOnBehalfOf, but I'm not, so I can't really remove that.
All the code is identical, just configuration that's changed. Not sure where else to look. Anybody have any suggestions for what to try?
FURTHER INFORMATION
I've tried the getUserInfo call in the SDK, passing the same access token I use for the other call. It returns successfully, showing that it is for the user I'm expecting, in the one group we have, on the production server. And yet, when I enable logging again, as this same user, there is still zero record in the resulting logs of any of this API activity.
Attempts to do things like list templates with the SDK fail with the same USER_LACKS_MEMBERSHIP error.
Using the Diagnostics API (again, through the SDK) to check logging status shows that it is NOT enabled (despite my enabling it in the UI), but can be enabled with a separate call. Subsequently attempting to use listRequestLogs in the SDK generates a 404 error, though the URL matches what's listed in the API documentation (/v2/diagnostics/request_logs). Not sure whether these findings confirm that I'm somehow logging onto the API and the UI with different users (even though the user name and internal ID match), or that there's some problem with the logging facility in DocuSign.
The problem turns out to be the URL I was using for API calls. I switched from demo.docusign.net in testing to www.docusign.net in live, but being in Canada we need to use ca.docusign.net. For those who find this later, you can get the correct base path to use from the oauth/userinfo endpoint, or the getUserInfo() call through the SDK (PHP SDK, at least; don't know what the analogous call would be in others).
There are 3 things to consider:
API calls are made to an endpoint (URL) that contains the account # (either GUID or short form) in the url. Take a note of that number in the url.
Auth Token is a token for a specific user in a specific account.
UserId for the specific call. That is a specific user in the account.
If the user is not in the account, or there's a mismatch between #1 and #2 - you'll get this error. You must work with a single account and have it in all places as well as the user must be a member of this account.
Re:
I have enabled logging, but the only things that are showing up in there appear to be from my own navigation in the site, nothing related to the API calls at all.
Since the request logging is not showing your API activity, the problem is that the person you've logged in as on the web tool is not the same as the person (user id) that you've logged in as on your application.
Solution for OAuth Authorization Code authentication: double check that when your app is logging into DocuSign, you're using the account.docusign.com authentication server, not the account-d.docusign.com auth server. (Look at the URL in your browser during the login sequence.)
Solution for OAuth JWT authentication: re-check that the impersonated user id is from the production system and you're using the right authentication server
I have created three B2C applications:
TestWebApp
TestApiOne
TestApiTwo
Both API applications were created the exact same way. Web API access is enabled, reply URLs have been specified, an App ID URL has been assigned, and keys have been generated. Both APIs have an additional read and write scope.
In TestWebApp API access, I am able to add TestApiOne with all three scopes without an issue.
When trying to add TestApiTwo to the TestWebApp API access list, the operation fails with the following error.
Failed to add the API access. Reason: The B2C service has an internal
error. If you created this B2C directory just now, please try again
after couple of minutes. If the problem persists, please contact
Support
(https://azure.microsoft.com/en-us/documentation/articles/active-directory-b2c-support/).
If you do not have a B2C directory you can refer

I thought maybe there is a limit of one API per application. To test, I created a temporary application "TempApp". I received the same error displayed above while trying to add API access for both TestApiOne and TestApiTwo.
Has anyone else experienced this issue?
There's not a limit of one API per application. I have done research and it works fine by my side.
Please have a look at the guide and check your steps.
I have tried to replicate the issues that you are facing by putting diff redirect reply url domains and also by making one application to be native and one normal web app but it doesn't help.
Could you try to delete all the webapps and try making 1 and then adding another to it.
Then create the 3rd one.
Please check this or if you can share some screen shots. That would be helpful.
You can definitely add multiple web apps to api access of one web app.
I have a web app in Azure. The access to that web app is controlled by Azure Active Directory. The app is up and running since September of last year. I didn't make any changes to the app for a while and have 33 users in that app.
So, a week ago I tried to add a user, using the same methods and paths I used before.
The new user can log in to microsoft (portal.office.com). After the initial log in and changing of the password the user goes to the web app in Azure and get the following error: You do not have permission to view this directory or page.
Error tracing gives me this:
HTTP Error 401.73 - Unauthorized You do not have permission to view
this directory or page.
Most likely causes: The authenticated user does not have access to a
resource needed to process the request.
Things you can try: Create a tracing rule to track failed requests for
this HTTP status code. For more information about creating a tracing
rule for failed requests, click here.

Microsoft Knowledge Base Articles:
Another observed behavior: usually when new users are logging in the web app asks for permissions for the AD to access their account information. Ever since this problem came up this is not the case any more.
Other users do not have any problems logging in. This problem only happens with new users who never logged in before.
EDIT: When I go to Active Directory and look at sign ins, I see failures to log into the web app with sign-in error code 90092. Failure Reason: Other.
Microsoft help desk could not give me details on that error code.
Checkout the related question and answer here. All new users have to first consent the application (agree and give your application permissions to access their profile / or you indicated as required permissions).
In short, you have to design "sign-up" button for your application, which uses the "login_url" and appends "&prompt=consent" to the query string.
Read all related resources here to better understand the consent framework.
And please read the documentation about Azure App Service Authentication/Authorization here, as well as the Azure AD specific documentation here.
OMG, I just found an answer. I created a test app and set it up to mirror the settings of my live app.
In Required Permissions the new app had nothing for Microsoft Graph, the live app had 5 permissions. I deleted Microsoft Graph and it works now!
I wish Microsoft communicated better about discontinued API's. I did get an alert, but it was mostly talking about MS Office 365.
I'm automating parts of my API Management tenant and suddenly receive '401 Unauthorized' messages in my code. Any ideas how I can detect why this is happening?
heck to see if you still have an authorization header included in your requests (as probably will be the case). In there you see a querystring like value starting with &ex=[SOME DATA/TIME VALUE]. Like this:
Authorization: SharedAccessSignature uid=53dd860e1b72ff0467030003&ex=2014-08-04T22:03:00.0000000Z&sn=ItH6scUyCazNKHULKA0Yv6T+Skk4bdVmLqcPPPdWoxl2n1+rVbhKlplFrqjkoUFRr0og4wjeDz4yfThC82OjfQ==
This probably is an expired date. Regenerate a new SAS in the portal or through code. In the Azure portal you can click on Manage and in the AAM portal you click on 'Security', as described here: https://msdn.microsoft.com/en-us/library/azure/dn798668.aspx#ProgrammaticallyCreateToken
