  2. Easy Auth OpenID Connect Provider - Support a Bearer Token

    We would like to use the Easy Auth OIDC provider with a Bearer token so that we can use client credentials grants with our API's.

    We tested the easy auth OIDC provider and were able to get code flow working with our IDP using these instructions:
    https://docs.microsoft.com/en-us/azure/app-service/configure-authentication-provider-openid-connect

    Adding bearer token support would allow us to leverage Easy Auth with our preferred IDP for both user and machine auth flows.

  4. Make WEBSITE_ADD_SITENAME_BINDINGS_IN_APPHOST_CONFIG to 1 by default or add warning

    We have been hit by hard restarts on web apps because we have not set the WEBSITEADDSITENAMEBINDINGSINAPPHOSTCONFIG to 1. It would be a more sane default to have it set to 1 by default, and then turned off by users that need WCF support OR have some sort of warning / checkbox or increased visbility in the portal.

    The simultaneous restart of all (in our case) 10 servers in a datasenter has caused outage of our services, and we would imagine others experience the same issue. I doubt many assume that all servers in…

  5. Allow FrontDoor CNAME for App Service Managed Certificate validation

    When creating an App Service Managed Certificate, it should allow validation if the CNAME is pointing to a FrontDoor with the same domain (or the FrontDoor's backend is the same Web App).

    Currently it gives the error "Hostname not eligible for App Service Managed Certificates creation" since the CNAME is not directly pointing to the web app.

  6. Add support for NetworkWatcher / NSG Flow logs for App Service with Regional Vnet Integration enabled

    At the moment, if one uses an App Service with Vnet Integration there is NO way to monitor the traffic that traverses this path. For organizations with requirements to monitor ALL network traffic for integrity / Security / Audit purposes - this presents a significant challenge as ALL traffic that traverses this integration is not able to be monitored. Since the App Service presents itself as on a given subnet within the Vnet - there should be NO reason that NetworkWatcher or NSG flow logs shouldn't be usable.

  9. Enable App Service without ASE to access Storage Account with Firewall enabled

    Currently it is not possible to configure storage account firewall to accept requests from App Services without ASE. This requires App Service to enable trusted access to storage: https://docs.microsoft.com/en-us/azure/storage/common/storage-network-security#trusted-microsoft-services.

    It is great if above is possible.

  10. Application Security Groups (ASG) support for App Service Environments (ASE)

    As stated in the comments section of this page https://azure.microsoft.com/en-us/blog/applicationsecuritygroups/
    "It's on the roadmap, all services integrated with VNet like ASE and SQL MI will be part of ASGs groups, as of today the scope doesn't cover subnets for those services, we are exploring options in the near future."

  12. Better inform users of when their App Service Certificates are about to expire or have not auto renewed (7 days?)

    This week another of our customer's sites went down due to an Azure App Service certificate expiring without us being notified of its pending expiry - we mark all App Service Certificates to Auto Renew and some of them do infact renew and rebind without our intervention, others certificates have got stuck on the domain validation phase (which we validated 1st time we bought the certificate ofcourse) and the latest certificate is now expired and the Manual Renew button is disabled as it seems to think its outside the 60 day renewal window.

  13. The Always On setting should have an option to make it sticky to the slot when swapping

    This is odd it isn't this way by default but should at the very least have an option to make it sticky so as to not break anyone's current practices (in fact, shouldn't more settings have the option to be sticky?).

    The issue here is that an always on slot consumes resources. If for example each app consumes 200Megs of RAM, and I have 5 app services running on a service plan, each app service has 2 slots for swapping, then I need to have Always On turned on unnecessarily for 10 slots (2gigs of RAM consumed for nothing). The…

  14. Allow for easier IP-restriction management on Azure WebApps (Advanced edit)

    Please make it so that we have a more convenient way to manage IP-restrictions on Azure WebApps. At the moment of writing IP's can only be added 1 by 1 manually or via an Azure PowerShell script.

    It would be a great change if you could make it like the Advanced Edit option that's available for Application Settings.

    Azure PowerShell and Azure CLI commands to support the management of an App Service Environments (at least v2). Hopefully this could include the ability to get management IP information, do scaling, and if it is an ILB ASE update the ILB Certificate.

  16. Auto-scale up and down not just out, for web apps

    Hi

    Can you expand the auto-scaling feature to include up and down scaling as well as in / out?

    so for example, scale the web app up a tier in peak and down a tier i off hours. Or something to that effect.

    Thanks

  17. Limit number of accepted client certificates when doing mutual TLS

    I want to be able to control the trusted issuers list sent to the web browser so that list of allowed certificates can be filtered in the browser. This was possible in IIS and with Azure Cloud Service I believe but how can we do it in a Azure web app?

    What I basically want to do is set the content of the certificate_authorities field in CertificateRequest sent by the server to the browser in the TLS handshake as stated in RFC5246.

  18. Allow adding same custom domains using ARM Template

    As described here it's now possible to add same custom domain on a WebApp using Azure Portal - link: https://feedback.azure.com/forums/169385-web-apps/suggestions/14128761-allow-adding-same-custom-domains-from-my-other-sub

    I've seen few apps now that when load balanced, require load balancer hostname added under custom domain in WebApp to work properly.

    Same should be possible via ARM. Currently when deploying WebApp resource there is a conflict if two resources share same domain:

  19. Provide acceptable scale out time for instances in ASE Isolated instance types

    Scaling is a core feature of App Services. We used ASE for the additional features however it means we are stuck with 40 mins scale out time to add an instance. Per support this is by design, however this is not documented anywhere in public domain.
    Scaling is supposed to help us get customers on to Azure, if it takes 40 mins to add an instance, it will not meet the business needs, we abandoned ASE only due to this issue. Kindly document current scale out time in public documentation so that user know this before hand.
    Ultimate goal should…

    Thanks for the feedback!

    You’re right that ASE scaling operations take longer than the common plans on multi-tenant App Service. We are looking at ways to decrease the time so it will on par with multi-tenant but this means a new infrastructure is needed with managing a pool or pre-assigned VMs to the ASEs.

    This is documented here, though without a time frame mentioned as it depends on a numbers of factors: https://docs.microsoft.com/en-us/azure/app-service/environment/using-an-ase#how-scale-works.

    We will update when there is more information here.

    Thanks,
    Oded

  20. Add wildcard pattern support for Azure Webapp _backup.filter file

    Right now _backup.filter does not support wildcards. Therefore, if logs are being produced say with a date or time timestamp, they can not be filtered unless they are moved to a seperate folder, which is then filtered. This is not viable in all cases.
