Custom authentication in Azure AD - azure

I am working on application where authentication is done by Web service which further calls our organisation AD service to authenticate.
Now I want to move my application to Azure but problem is my web service is not exposed outside organisation. So I can't use web service on Azure to authticate.
Then I searched for Azure AD and found that Azure AD it self provides authenticate and store users data to their data center.
How can I integrate my organisation AD account to Azure AD ?

You are probably looking for Azure AD Connect. See

Is it possible to use Azure ADB2C as an IDP for federating google cloud identity apps

Scenario:
Managed GCP Applications hosted on GCP with a Google cloud identity setup for customers
Want customers to access GCP managed service using their own IDP
Question:
Can I use Azure AD b2c as an IDP for Google cloud identity ?
Looking for a solution or alternate solutions which may not be that expensive
Azure AD B2C is an OIDC IdP so yes, it can be used as a federated IdP in Google Cloud Identity. Due to the similarities between Azure AD B2C and Azure AD you can follow most of the steps detailed in Configure workforce identity federation with Azure AD and sign in users with the following Azure AD B2C specific replacements:
Create a new app. As a best practice, we recommend that you create a new application in Azure AD B2C and use only the application to obtain Google Cloud credentials. To create a web app for user sign-in with Azure AD B2C and enable your app to receive tokens from Azure AD B2C, see Register a web application in Azure Active Directory B2C.

Mattermost and Azure AD integration

I am trying to configure Azure AD as a part of single sign in Mattermost. However, I'm not able to find any relevant documentation.
Any leads could help.
I have already gone through the following documentations -
https://docs.mattermost.com/onboard/sso-office.html
https://docs.mattermost.com/onboard/ad-ldap.html
I'm not sure if these documentations are relevant.
Mattermost integrates with Azure AD using Open ID Connect authentication to enable SSO between Azure AD, Mattermost and other Azure AD enabled apps using Azure AD credentials.
Basically, you need to setup or own an Azure AD Tenant (Dismiss the Social and local accounts section), create an app registration and configure OpenID Connect authentication as detailed in the Mattermost documentation.
https://docs.mattermost.com/onboard/ad-ldap.html is intended for on-premise Active Directory using LDAP which is not supported in Azure AD.

Can we configure SSO (Single Sign On) in Azure without using Azure Active Directory?

Can we configure SSO (Single Sign-On) in Azure without using the Azure Active Directory? Or using any Code.
If you need to log in with Azure AD users then SSO is required for Azure AD. If you have your own database of users to login and then you don't require Azure AD.

Azure AD B2C to authenticate corporate Azure AD accounts

Azure AD B2C newbie here. I have a Single Page Application hosted in Azure & it uses Azure Functions. I want to allow users in many organisations to login to my application using their existing corporate email address, & authenticated in their company's Azure AD, which I have no access to.
For instance I want people in company Contoso to access my Azure SPA by logging in with their existing Contoso email addresses "john.smith#contoso.com". Authentication takes place in Contoso's Azure AD.
Do I use the Azure AD B2C Identity Experience Framework & Custom Policy for this? Any guidance would be helpful.
This isn't the best case for use of Azure AD B2C.
I recommend you use the "multi-tenant" pattern to configure your single-page application to accept sign-ins from any Azure Active Directory tenant

Azure AD authentication without app registration

I want to access Azure Directories and Subscriptions using my web app hosted on my server but i do not want to register my app in active directory because
i do not have permissions to register my app in active directory
I want to authenticate users from out of my active directory too.
for example following sites let you authenticate any Azure AD user.
https://resources.azure.com/
https://azureiotsuite.com
Please help me to where to start. i have tried Azure AD authentication but it asks you to register your app in Azure AD Apps.
One option is to register your app at https://apps.dev.microsoft.com. (And use the v2 endpoints)
Documentation here: https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-appmodel-v2-overview
What you want to make is known as a multi-tenant application. An application to which you can login from any Azure AD tenant.
The first link leads you to create a converged app which allows you to use Microsoft accounts as well as Azure AD accounts to sign in.
If you only want Azure AD accounts, you could just create an Azure AD and register the app there as a multi-tenant app. (And use the v1 endpoints)
