I have a Windows service running as a an AD user. I do not have the password for this user (not without storing it in a file somewhere).
The method signatures for VaultSharp LDAP auth all want a username and password, but is there any other way of automatically granting access using something like UserPrincipal maybe?
No. VaultSharp is a reflection of all the features of Vault.
And I don't think Vault supports the "integrated windows mode" of auth. It expects a password in its LDAP login.
If you find any Vault API docs, that does support what you are looking for, let me know.

I am stuck at this issue while sending request for Azure Active Directory authentication from ASP.NET, using UserPasswordCredential, I get this error :
{
"AADSTS50076: Due to a configuration change made by your administrator, or because you moved to a new location, you must use multi-factor authentication to access '00000002-0000-0000-c000-000000000000'
Note : MFA is enabled.
Does any one know why this issue occur ? how to ignore MFA authentication while authenticate from API side.
Is there any policy to handle MFA authentication?
The documentation for UsernamePasswordCredential Class clearly states this will not work:
Enables authentication to Azure Active Directory using a user's username and password. If the user has MFA enabled this credential will fail to get a token throwing an AuthenticationFailedException. Also, this credential requires a high degree of trust and is not recommended outside of prototyping when more secure credentials can be used.
For an alternative solution, please see the documentation on Managed identities for Azure resources.
I need to support 3 way of authentication at the same time in the application: LDAP, Azure AD, Basic.
After few hours of googling i found that the best way to do it would be to implement 3 authentication providers and then register them with AuthenticationManagerBuilder. But the issue i stumbled into is, that i dont know how the make the Azure Ad provider. For LDAP i found an online example i can use, and based on the LDAP i could probably also make the Basic username and password provider, but havent found anything similar on Azure AD. All i have found is that, i need to add 2-3 dependencies to the project for the Azure AD and then it automagically works.
I dont understand spring security that much, so im stumped atm. Can i just trust the automagic to do everything correctly, or are there some resouces on how to create AzureADAuthenticationProvider i could use with AuthenticationManagerBuilder?
An authentication provider is an abstraction for accessing user information from LDAP, custom third-party source, database etc. it validates the user credentials.
Spring security with azure ad:
Firstly, azure ad is integrated with Spring security for secure your application.
User login through their credential and get validate by azure AD.
From azure graph API you have to access token and membership information.
Membership for role based authorization.
LDAP Authentication:
Unique LDAP or DN ,you can perform search in directory unless you know username to DNS is known in advance.
You can authenticate the user by binding that user.
Load the Number of authorities for the user.
Custom Authentication Provider:
Create own authentication (custom) with the help of authentication provider interface in which you can use
authenticate method and implementing it and make authentication object with username and password of user
Then after you can configure these authentication in spring security configuration.
Here is the Reference Link regarding Spring Security
I have the following requirement:
create a user on AD B2C.
using the credentials of that user, I need to get access token and refresh token to access an existing api(REST SERVICE).
Active directory here is Azure AD.
I am new in oAuth and Azure. Please suggest me the steps and configuration to achieve this. (I do not want any user interaction to get access token and refresh token).
creating a user is clear to me. but if it requires any specific type of user or any required permissions, please suggest those.
To me, it sounds like your use case can be better realized with a service principal. If you don't need a user context but, consider using an SP instead. See:
Microsoft identity platform and the OAuth 2.0 client credentials flow
If for whatever reason you want to stick to non-interactive user login, you can use the Resource Owner Password Credentials flow. But be aware that:
Microsoft recommends you do not use the ROPC flow. In most scenarios,
more secure alternatives are available and recommended. This flow
requires a very high degree of trust in the application, and carries
risks which are not present in other flows. You should only use this
flow when other more secure flows can't be used.
Currently we are a Service Provider (SP) which is currently using SSO Authentication using OpenAM and we are using Spring security to achieve this.
We have a login interface where user enter user name and password and authentication happens.
Now we have a requirement to allow users from an external identity provider (Azure) to access the SP in addition to the existing Open AM SSO. We are trying to use SAML 2.0 to achieve this.
For this we changed the login interface, to accept the user name and based on the user name, we either provide the password option (for local users ) or redirect to the azure portal (for idp users) to authenticate the user.
As part of this requirement, we added a variable userType into httprequest cookie and try to redirect to the respective authentication provider. But we always get redirected to azure even though the user is a local one.
We have gone through many examples from github to implement this but no luck.
Any pointers on this would really be helpful.
I'm working on integrating Azure AD authentication with various apps on different platforms.
Is there a way to get an authentication token id from a user logging in through a web api like 'azureadlogin.com/login?user=ted&password=passwordhash'
There seems to be ways of doing it through node or javascript or C# apps but I'd really like to just have a simple web request way of doing it as there are many different apps on different platforms that need to make use of this feature.
No.
There is a way to authenticate with username + password by doing a POST request and using Resource Owner Password Credentials flow, but I don't recommend it.
ROPC will not work if:
User's password has expired
User is MS account/federated from on-prem AD
User has multi-factor authentication enabled
You have a wide selection of authentication flows which work in all these scenarios too, and don't involve the user giving their password to you.
For example:
Authorization code flow
Implicit grant flow
Device authentication flow
You can use username/password authentication. But if your app has user interface, so it could popup the regular Azure AD login page, I would recommend not to use it. A major reason for using Azure AD (or other identity providers) is that the user doesn't want your app to know his password.
There's a sample which does what you want. The code in question is here.
The sample uses .NET and the ADAL.net library, but you can do similar stuff on other platforms.
