I have a jenkins server installed on ubuntu in our esx environment of office.
It is local VM, can be thought of.
How to use azuread for login to this jenkins?
Every employee has company email ID, which was created with azuread.
I want to use that instead of creating users again on this jenkins.
In order to add Azure credentials Within the Jenkins dashboard, click Credentials -> System ->. Click Global credentials(unrestricted). Click Add Credentials to add a Microsoft Azure service principal by filling out the Subscription ID, Client ID, Client Secret, and OAuth 2.0 Token Endpoint. Provide an ID for use in subsequent step .
In Order to have Authentication and Authorization Via Azure Active Directory kindly check this two document.

Our use case is to connect Azure Datafactory (ADF) to AWS S3, but use the Managed Identity (MSI) of ADF for authentication and authorization.
TL;DR version
The problem we run into is that we require the access_token for the MSI in ADF, so we can exchange that for temporary credentials in AWS IAM service. We need this access_token in text, such that we can provide it in the right way to the IAM service.
Situation (longer version)
High over, the solution should work like this:
ADF will get an access token for a specific resource using MSI
Using the access token, ADF will then get temporary credentials with AWS
Using the temporary credentials, ADF will get data from S3.
In order to do this, we needed a couple of things (heavily inspired by this blog):
Azure side:
We created an App Registration, and set an Application ID URI (which will be the 'scope' claim in the AzureAD access_token request).
We created a custom role in that App Registration.
In the Enterprise Application object of this App Registration (at this point, I feel like I should appologize for Microsofts terminology..), we have ensured that User Assignment is required.
We have assigned the custom role to our ADF MSI.
AWS side:
Added our AzureAD as an Identity Provider
Set the audience to the same value as Application ID URI.
Added a new role with a trusted entity of type Web Entity, and added proper S3 permissions to it.
Then to test this all out, we created an Azure Function (http triggered) which returns the request headers as body. We then created a Web Activity in ADF to this Azure Function endpoint, and set the authentication to "System Assigned Managed Identity", with a resource the same as the aforementioned Application ID URI. The result is that we get the Authorization header value, which we then manually put into a request to the AWS IAM service to exchange for the temporary credentials. The request to the AWS IAM service has the format of https://sts.amazonaws.com/?Action=AssumeRoleWithWebIdentity&RoleSessionName=app1&RoleArn=<arn>&WebIdentityToken=<access token>. This provides us with credentials, which can be used in a Linked Service in ADF (we tested this).
Problem statement
We now use Azure Function, in order to have ADF automatically get an access_token for the requested (AWS) resource (Application ID URI), and add that access_token to the request to the Function, which solely returns it to us. We want to do this without an additional component. I can think of two ways:
(option 1) - A web activity to some Microsoft endpoint that returns the access_token immediately.
(option 2) - Have AWS take an Authorization header rather than a WebIdentityToken query parameter.
I spent some time on option 2, but that seems like a no go; the access_token really needs to be part of the URL parameters when trying to exchange them for temporary AWS credentials.
Option 1 however, I had an idea; there is the IMDS on virtual machines in Azure. This can be used to get access_tokens when you are on a VM rather than a PaaS service. I tried making a call to http://169.254.169.254/metadata/identity/oauth2/token?api-version=2021-12-13&resource=<Application ID URI> using Web Activity (both with a AutoResolveIR and a SelfHosted IR!), but I got the error [ClientSideException] Value does not fall within the expected range. I did set the header Metadata to value true as described in the docs.
Is there another way? Apologies if this is an abundance of information, but it does provide you with all the required details of what has been tried and how the setup should (and can) work.
It sounds like you're using Azure AD as an identity provider in AWS. If possible, you can create a AWS user with a permanent access key/secret key. The AWS user can have access to your S3 buckets, and you won't need to deal with STS in ADF.
Another idea is to use Azure KeyVault. When you create your S3 linked service in ADF, you can parameterize the access key and secret key. Your AWS access key and secret key will be stored in Azure KeyVault. Then you can have a Azure function that updates the KeyVault on a schedule or at the start of your ADF pipeline.
To obtain the access token, you could try using the Azure REST API. To obtain the access token for the specified resource using the MSI, you might use a Web Activity in ADF to make a REST API request to the Azure REST API endpoint.
Set an Application ID URI and create an Azure AD app registration.
The app registration should include a custom role.
Give the ADF MSI the custom role.
REST API calls to the Azure REST API endpoint that return the access
token for the specified resource using the MSI can be made using a
Web Activity in ADF.
The URL for the REST API is:
https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token
{tenantId} should be changed to your Azure AD tenancy ID.
In the REST API call, enter the following values:
grant_type: client_credentials
client_id: <application_id>
client_secret: <application_secret>
scope:
We are trying to connect a javamail (1.6) client to our office365 mailbox hosted on office365 using OAUTH2 authentication.
No matter what we do, we keep getting A1 NO AUTHENTICATE failed.
We have registered our application with
API Permission
we followed all instructions stated at
https://learn.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth
including running the powershell commands to create the principal using the app id and object id, and we granted the app full access to emailbox we want to access.
For authentication we do an HTTP POST as following which generates an access token
This is a client credentials flow with shared secret as explained here
https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow
https://login.microsoftonline.com/{our tenant id}/oauth2/v2.0/token
with
client_id=...
client_secret=...
grant_type=client_credentials
scope=https://outlook.office365.com/.default
our javamail configuration
mail.store.protocol="imap"
mail.imap.host="outlook.office365.com"
mail.imap.port="993"
mail.imap.ssl.enable="true"
mail.imap.starttls.enable="true"
mail.imap.auth="true"
mail.imap.auth.mechanisms="XOAUTH2"
mail.imap.user="<email box>"
then in our java code we connect the store with the access token obtained from the above HTTP POST
store.connect(host, user, oauth2_access_token);
We also tried this powershell script, which returns the same error
https://github.com/DanijelkMSFT/ThisandThat/blob/main/Get-IMAPAccessToken.ps1
I do not believe that problem is specific to JavaMail.
It is extremely difficult to determine if an access token has the correct rights or there is something else that prevents the authentication
What else can we try?
Update 1
If we use the powershell script
https://github.com/DanijelkMSFT/ThisandThat/blob/main/Get-IMAPAccessToken.ps1
passing only the client id and the redirectUri the script prompts me for approval and it succeeds
but if we use clientsecret authorization fails
Update 2
I can successfully use javamail with the access token generated by the powershell script.
Clearly the token created with the clientsecret does not have enough rights to access IMAP or the mailbox
I start to wonder if token requests using client secret do not work because our Azure Active Directory has "security defaults" enabled.
May be MFA is enforced therefore any non-interactive requests are blocked
Update 3
https://jwt.ms allows to decode access tokens
The token created with just the clientid (code grant flow) is very different from the one created with the client_secret (client credentials flow).
In token from "code grant interactive" there is an attribute called "scp" Set of Scopes, which lists scopes regardless of what I have in my client app API permission ????
"scp": "IMAP.AccessAsUser.All Mail.Read Mail.Read.All Mail.Read.Shared Mail.ReadBasic User.Read"
The second token from the client credentials flow, has an attribute "roles", but does not have scopes
"roles": ["IMAP.AccessAsApp"]
RESOLVED!
looking at the access token we noticed that the client credentials flow subject (sub) was an id that we did not setup.
Here is the catch: when creating the service principal using powershell in exchange online, for serviceid you have to use the objectid of the enterprise application.
New-ServicePrincipal -AppId {clientid} -ServiceId {enterprise application objectid} -Organization {tenantid}
When creating an app registration Azure AD, you also create an enterprise application
The application object id is different from enterprise application object id.
The client credentials flow uses the enterprise application object id as the user asking for authorization.
The same for granting access to the mailbox using powershell
Add-MailboxPermission -Identity {email} -User -ServiceId {enterprise application objectid} -AccessRights FullAccess
it is unfortunate that the authentication process is so cumbersome
My two cents on this , if you are still facing authentication failure from javamail trying to connect to mailbox and read emails, First and foremost make sure the application setup in azure active directory has below permissions.
IMAP.AccessAsApp
Mail.Read
Mail.Send (For Sending)
Secondly, Create service principal with the enterprise application id as mentioned in the original post.
Once done check here if your generated token has all the roles you have assigned.
Even if you assigned necessary roles and you can able to connect to mailbox via powershell still you might get AUTHENTICATE failed from javamail because you might be using this property (mail.imap.auth.mechanisms) wrongly , replace mail.imap with mail.imaps and it should solve the problem.
"mail.imaps.auth.mechanisms"="XOAUTH2"
"mail.imap.host"="outlookoffice365.com"
"mail.smtp.port"=993
"mail.store.protocol"="imaps"
session.getStore("imaps")
store.connect(host,port,user,token)
Good luck !!
I am setting up a PowerAutomate flow which will be called from a PowerApp. I would like fetch a JWT token from Azure AD in Power Automate and use that token to authenticate call a REST API, return back the result to PowerApps.
However, I would the JWT token be generated for the user which executes the flow and I dont want to hard-code user credentials in the flow. There would be multiple users executing the flow and each user would have different permissions in my App ( to which the REST call is made) so I want the authentication to the app be done as a named user rather than a service account/generic account
Thank you #lona Varga for your valuable suggestion. Posting your suggestion as an answer to help other community members.
To authenticate your application as a named user, please try the
following:
Create both backend and client application registrations in Azure portal.
After configuring these, create a custom connector by updating your security setting as below:
Authentication type: OAuth 2.0
Identity Provider: Azure Active Directory
Client ID: Client ID for Client App Registration
Client Secret: Client Secret for Client App Registration
Resource URL: Client ID fot Backend App Registration.
Update the redirect url by removing the existing value and add this newly created one, this is same for all connectors and it is :
https://global.consent.azure-apim.net/redirect
For more in detail, please refer below link:

I have a requirement to integrate azure SSO to the WebApp. My WebApp is built in FastAPI. Currently I implemented it by referring https://pypi.org/project/fastapi_msal/. It's working and giving me logged in user information which I need. But the usecase which i need is little different from this, This link implemented as user should enter clientID & Client Secret. But in my case on button click or on page load user should directly login it should not prompt to add clientID & Secret.
How i can achieve this? I am not getting any proper document WRT FastAPI
For the scope that you can get are identified in the app registration api Permission and NOT "delegated permissions" client credentials flow cannot get delegated permissions flow.
Once you give an application permission, you have to click grant for tenant. If you don't it won't be able to use it. This option specifies the client secret for the confidential client app. This secret (app password) is provided by the application registration portal or provided to Azure AD during app registration with PowerShell AzureAD, PowerShell AzureRM, or Azure CLI.
Read more here for more information on client secret.
We have a Jenkins installation that uses the OpenID plugin to authenticate our company users. The problem we have is that our source control (Kiln/Mercurial) pushes notifications to Jenkins either anonymously or via username/password. As all users use OpenID I cannot use username/password. So with that being said what is the minimum set of permissions for an anonymous user to be able to kick of a job build in Jenkins?
If you use matrix-based security (or project-based matrix), the user needs to have the "build" column in the "job" group ticked.
