We are integrating keycloak with azure entra via OIDC. We have created custom security attribute to map some extension fields for the user. We tried to map these as tokens, but the custom security attributes doesn't show up in the dropdown under the token > add optional claims We then tried to define them under the Enterprise App > Single SignOn > Attributes & Claims; but unable to find these custom security attributes in the drop down there either ! Any help for this problem is deeply appreciated. Thanks, Raghav21Views0likes0CommentsEnable MFA method

Hi all, we're on the path to creating a Multitenant Organization (MTO) for our global organization. We already have a relationship with one partner tenant which has B2B Collaboration and B2B Direct Connect set-up and is working well. We took the step of creating a Multitenant Organization in our 365 admin center and started testing with a sandbox tenant, which has since been removed. The issue we are having now, is that guest users which are not part of B2B Collaboration or an MTO cannot have their redemption status reset. I first found this wasn't possible from the error in a Power Automate workflow using Microsoft Graph, then confirmed I got the same error in Entra ID. The documentation for MTO was updated a few days ago and includes this, saying that as part of a multitenant organization, reset redemption for an already redeemed B2B user is currently disabled. But should this be the case for guest users not part of B2B Collaboration or Multitenant? Is this an error or expected behaviour, I wonder? Thanks!1.3KViews1like1CommentMultitenant collaboration - share users - can't choose groups
Hi all, I am configuring the new multitenant collaboration now that it's out of preview. When I last was testing it in preview, when I clicked "Share users" I was able to select an Entra ID group of users to share. Now the behaviour is different, it's only allowing me to select users', not groups. Am I missing something obvious here? Thanks!448Views0likes1CommentGuest accounts and MFA via Conditional Access in MS Entra
Hi experts, trying to get some help on my scenario and issue that external users started to experience since I've enabled MFA for external identities & guest users via Conditional Access. We have lots of external partners that we share some documentation with from our SharePoint. Some time ago, I have enabled "MS Entra B2B Integration for SharePoint and OneDrive" so that any external user that access shared files/folders in our SharePoint gets a GUEST account created in our tenant. This was also preparation for enabling MFA for External users via Conditional Access. I believe these are called "B2B Collaboration guests" Now, few days ago, I have enabled MFA via Conditional Access for all external users and guests, enabled for all cloud apps and require MFA to grant access. Until now, I got feedback from two external partners that their existing access doesnt work anymore - and they need to go through MFA (which is expected). The problem is that when they go through MFA set up, it ends up in a "loop" - meaning, they go through all steps but when completing the last step they are returned back to the very 1st step again. So they: scan QR code successfully authenticate get the page that it was successful get back to the 1st step asking to install or use MS Auth app The user tried different browsers also with Incognito tabs... When I am checking sing-in logs: guest account is created fine the status is: "Interrupted" additional details: The user was presented options to provide contact options so that they can do MFA. conditional access forcing MFA is marked as FAILED as MFA was not completed Both external partners that reported this are using MS Entra and I see their IDENTITY as ExternalAzureAD. Have not heard back from anyone else using other than ExternalAzureAD so not sure if there is something extra that needs to be configured. Anyone experienced this issue? Any idea what can be wrong? I do not have any cross-tenant collaboration etc configured...287Views0likes4CommentsB2B Direct Connect + cross tenant access enables switch tenants functionality?
We have set up a b2b direct connect connection with another company. We have enabled the cross-tent sync settings. We want to use Shared channels in Teams. This works fine. It is now possible for the other company to switch tenants in Teams and log into our tenant and then they see the entire team and not just the shared channel. The can also access SharePoint sites. Is this works as designed because I can't find this functionality in the Microsoft documentation.Solved355Views0likes2CommentsIs it possible to disallow proxyAddress as Sign-In Identifier?
As part of a revised naming scheme for user accounts we're planning to roll out, I'd like to disallow Exchange Online email addresses and proxyAddresses from being used instead of the User Principal Name as an alternative identifier when users sign in to their accounts. This is supposed to strengthen security as users don't share one of the authentication factors with every email they send and the user names can't be easily guessed because they don't use the actual first or last name of the user behind them. This is the only Microsoft Learn article I found that was describing something similar: https://learn.microsoft.com/en-us/entra/identity/authentication/howto-authentication-use-email-signin Basically I want to do the opposite of what the article is describing and I'm not synching my users using Microsoft Entra Connect. I disabled the "Email as alternate login ID" option described in the article anyways but unsurprisingly, that didn't have the desired effect. Does anyone know if this is even possible and if so, how to do it? Thanks in advance! This is my first post in this community. If I did something wrong (like choosing the wrong label) please be kind, tell me, and I'm going to adapt my post.Solved367Views0likes2CommentsPhishing resistant MFA options for Entra ID Guest users
What are the phishing resistant MFA options for Entra ID B2B guest users who authenticate from an IDP that is not configured for inbound cross tenant trust? From our testing, there does not appear to be any way to use fido2/passwordless/certificate-based authentication with the guest account on the resource tenant. The following links appear to indicate that this is not supported. Overview of custom authentication strengths and advanced options for FIDO2 security keys and certificate-based authentication in Microsoft Entra ID - Microsoft Entra ID | Microsoft Learn Microsoft Entra passwordless sign-in - Microsoft Entra ID | Microsoft Learn When we enable MFA requirements in conditional access policy for Guest users, the only option that seems to work is MS Authenticator which the user can enroll for on our tenant. Would switching the account from a B2B guest to an internal Guest allow something like CBA to function or is the only real option to enable cross tenant trust and force the user to enable MFA on the account in their home IDP?351Views0likes0CommentsAzure B2B show guest user SPO and onedrive people picker
Hello, i want to add "guest user" from other tenant to our tenant. it is a kind of federation between 2 firms. So the users should find users from other firm with an easy way to share documents and sharepoint sites/libraries. I also want to see this users in the "people picker" for sharing SPO websites and also Onedrive sharing (also desktop client). i have used: "Set-SPOTenant -ShowPeoplePickerSuggestionsForGuestUsers $True". But: my guest users are not visible in people picker when i try to share website and also not available on onedrive sync client. Do i need to run Set-SPOSite -ShowPeoplePickerSuggestionsForGuestUsers $True for every existing site? How about onedrive? do i need to enable the Guest suggestions also with command?
