I am trying to get access to users specific Key Vaults secrets on behalf of the user and am a bit confused about how the Azure IAM access polices work together with Key Vaults access polices. What I want to do is grant the Application access to users specific Key Vault.
Reading the Azure Key Vault docs it seems that "User plus application access/compound identity" would allow me to do that. However I can't seem to find any examples of this implementation in Azure docs. I thought that "Select Principal" = user and "Authorized application" = service_principal configuration in Key Vault "Add access policy" tab specifies what application can access which Key Vault on users behalf but "Authorized application" option does not seem to have any effect.
I am using App/Service Principal OAuth authorization to check if the user is in AD graph and after that am trying to access users specific Key Vault on users behalf.
Access policies that I have currently tested and are not working for me:
Configutation where Service Principal do not have Delegated permissions to users Azure Key Vault service
Can't access Key Vault no matter what is IAM or Key Vault access policy - Azure will give "Consent required error" on token request.
Configurations where Service Principal has Delegated permissions to Azure Key Vault Service
When Key Vaults access policy has been set for user/user and service principal, I can access Key Vaults secrets on users behalf.
This however applies to any of the Key Vaults that user has, which I do not want.
Could anyone point me in the right direction on how to access users specific Key Vault on behalf of the user?

Thousands of secrets are there in my azure key vault.
So whenever I need to check/see the secret value at the Azure portal, I will need to scroll up to the end after loading all the secrets multiple times.
Is there any shortcut apart from API, available to see the same?
For now, the search text box in keyvault to search for a secret is not supported. You can vote up this feedback to promote it to be achieved.
However, you can access Azure Key Vault Secret through Azure Key Vault REST API.
We will start by registering an app in Azure AD and then add that app in the access policies of the key vault.
Then create a new request in Postman to get the access token.
https://login.microsoftonline.com/{{directoryId}}/oauth2/v2.0/token
After that we will send a couple of http requests to get access token and to get a secret’s value.
https://yourkeyvaultname.vault.azure.net/secrets/Secret1?api-version=2016-10-01
Try the Azure CLI:
az keyvault secret show --name "secret-name" --vault-name "keyvault-name" --query "value"

You can also use the KeyVaultScannerUtility to perform required search and update operations on Azure KeyVault. Do check it out and let us know if its useful.

Been struggling with this for a day, and am finally reaching out for help. I'm attempting to use Azure Key Vault to store some configs in a Typescript application. I've created a service principle in Azure Active Directory and a Key Vault. In the Key Vault, I've gone to Role Assignments and given the app the role Key Vault Secrets User (which should provide list and read permissions). From what I can tell, my app is successfully authenticating, but when it requests a secret, it is getting a 403. What step could I be missing?
Log which suggests the authentication was successful
azure:identity:info IdentityClient: [https://login.microsoftonline.com/38e3589f-a40f-4fe6-beee-f4028442450e/oauth2/v2.0/token] token acquired, expires on 1593536920022
Log with the failure

The step I missed was adding an Access Policy. I don't understand the difference between Access control (IAM) and Access Policies, so I don't understand why both are required. Hope this helps someone else.
I don't understand the difference between Access control (IAM) and Access Policies, so I don't understand why both are required.
Actually, to access the secret in the keyvault, the permission in Access Policies is enough.
The access of the keyvault is divided into two parts, management plane(Access control (IAM)) and data plane(Access Policies).
The permissions in management plane let you manage the keyvault, e.g. set Key Vault tags, the permissions in data plane let you do operations on the secret, key, certificate.
In your case, even if you give the app(service principal) an RBAC role in the Access control (IAM), it will not have the permission to access the secret, so you need to add it to the access policies.
Something you should note is some roles have the permission to add access policies, e.g. Contributor, it means if you give the role to your app, it will be able to add itself to the access policies. But if it does not add itself to the access policies, it will not have the data plane permission.
For more details, you could refer to this doc - Secure access to a key vault.
I am trying to limit access to the secrets/certificates so that only certain users can view/access some of them.
How do I go about doing that?
limit access to the secrets/certificates so that only certain users can view/access some of them.
In short, it's impossible.
You can limit only certain user to access all the secrets or certificates, other than access some of the secrets.
Simply find the Azure Key Vault in the Azure portal UI, click Access policies under settings, and add a new access policy. You can define fine-grained permissions for accessing Key, Secret, and Certificates (which Azure Key Vault can also store, by the way). However, when you allow some user to access your key vault secret, they will access all the secrets in azure Key vault.

I have a web application that is leveraging Keycloak for IdM.
I am using the Resource Owner Password Credentials or Direct Grant flow for authentication which uses REST API calls to /auth/realms/{realm}/protocol/openid-connect/token instead of browser redirects to get the user a JWT.
I would like to implement a similar workflow for signing users up.
Looking at the Keycloak documentation it appears the Keycloak Admin API exposes an endpoint for this at /auth/admin/realms/{realm}/users.
To allow clients to interact with the Keycloak Admin API you have to create a client service account and associate it with a keycloak role with sufficient privilege to manage realm users.
The expected approach for this seems to be to apply the manage-users realm specific role to the client service account. This is more permissions than I would like to grant to the client.
Is there a way to grant a client service account just the ability to create new users and not the full set of permissions that comes with manage-users?
When we are trying to retrieve secret from keyvault using KeyVaultClient (c#) we are getting 403 access denied even though the same user can access the vault secret from Azure Portal. If we give explicit access to the user on key vault then we are able to retrieve the secrets. This looks like an issue and please help on possible workarounds.
You may not have a service principal created for your application yet. If so, create that first and then use the object ID of the service principal to authorize access for the application. If you are using a VM you also need to add the VM service principal to the Keyvault's policies.
Take a look at this sample code to see how to create application and service principal and give permission to the service principal.
This was due to while generating token Group claims were not getting set and hence key vault was checking only of direct permissions. Once we enable group claims by following these steps from here then it is working fine now ..
