@cwarnermm I glanced at it and I spotted a few things that are incorrect.. going to take my time to |

| * Commit to Azure AD ``objectId`` as the authoritative identity. | ||
| * Ensure all authentication methods (OAuth, SAML, LDAP) resolve to the same value. | ||
| * Confirm access tokens include the ``oid`` claim. |

this will be part of the configuration steps when configuring in Entra, not sure this is needed here.

Is it accurate to say that Entra configuration enforces these conditions, or should we phrase this as "must be validated by the admin during Entra setup"?
| * You require Android Intune MAM support (not yet available). | ||
| * Your deployment cannot use Microsoft Entra ID (Azure AD). | ||
| * Your identity strategy cannot use Azure AD ``objectId`` as the authoritative user identifier. | ||
| * You need a rollout model where users can defer or bypass Intune enrollment. |

This point is interesting, cause they can have multiple login methods, only the login method selected in the Intune MAM configuration in the system console is subject to this.
There was a problem hiding this comment.
I think we need to make this clearer.. for example they can have users with another login method and this is then a false statement, guest users and again this is a false statement.

not at all.
Register an Application in Entra that will be use to authenticate the users.
this link works To register an application in Microsoft Entra, see: https://learn.microsoft.com/en-us/entra/identity-platform/quickstart-register-app and we can keep that, but probably best to direct them to configure this for Single tenant
The redirect URI should remain empty
Once the app is registered, they should Expose an API more info here: https://learn.microsoft.com/en-us/entra/identity-platform/quickstart-configure-app-expose-web-apis
The API to be exposed should be api://<APPLICATION-ID> normally filled automatically, then add a scope named login.mattermost
Once that is done, they need to Add a client application, add the Client Id as listed below and assign the Authorized scopes to api://<APPLICATION-ID>/login.mattermost
- Mattermost Mobile Beta:
64e9952b-20eb-46dc-92ad-99089ed24903 - Mattermost Mobile:
not yet created, we will need to update this document
in addition I will share a script once we have the Client Id for Mattermost Mobile so we can attach it here.
Then in Token configuration -> Add optional claim, Select Token type Access then select the claims
- family_name
- given_name
- preferred_username
- upn

To finalize the documentation, I'll need:
- Production Mobile Client ID
- Confirmation that
login.mattermostis the final scope name - Confirmation that all listed access token claims are mandatory
- The script you mentioned (or guidance on where it will live)

this does not happen during sign-in only if Intune is enabled mid-session

this is only if the policy enforces a PIN

All of these are enforced or not depending on the Intune policy, perhaps we should point to a microsoft documentation that explains each policy or we should try to be broad with the explanation.

@cwarnermm let me know if you would like us to have a sync session to go through all this.

| If any of the above are not true, do not proceed. |

they can proceed even if the users aren't created when logging in with SAML on the mobile app.
| * Commit to Azure AD ``objectId`` as the authoritative identity. | ||
| * Ensure the authentication provider selected for Intune MAM enforcement (OIDC or SAML) is backed by Microsoft Entra ID and resolves users to Azure AD ``objectId``. | ||
| * If LDAP is used to provision those users, LDAP must also resolve the same Azure AD ``objectId``. | ||
| * Confirm MSAL access tokens include the ``oid`` claim. |

this looks like is part of Step 2
|
|
||
| * Enable Intune MAM in the System Console. | ||
| * Set ``IdAttribute = objectId``. | ||
| * Verify Enterprise Advanced licensing. |
| Step 5: Validate Using the Mobile App | ||
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | ||
|
|
||
| * Ensure test users are assigned in Intune and properly licensed, and perform the first validation login using a Microsoft Entra administrator account that can grant tenant-wide admin consent. |

this part is only a recommendation
| * OIDC (Microsoft Entra-backed), or | ||
| * SAML (backed by Microsoft Entra) | ||
|
|
||
| 4. Set ``IdAttribute`` to ``objectId``. |

I wonder if we should provide a Step by Step bullet point or something on how to actually configure this, I think this guide says a lot but if the person doing this do not have Entra / Intune experience they may not know what to do.
| Sign In to Enroll | ||
| ----------------- | ||
|
|
||
| You only need to complete enrollment once per account. |
There was a problem hiding this comment.
this is not really true, this happens each time you login
| 2. Sign in with Microsoft (your organization’s sign-in option). | ||
| 3. Enter your credentials. | ||
|
|
||
| During enrollment, you may be asked to confirm your Microsoft sign-in again. This is normal and usually takes only a few seconds. |

absolutely DOES NOT happen, the only time you are asked to do this is if Intune is turned on mid-session
