We are trying to fine tune our SSO experience on our macOS devices.
Our JAMF Connect application is working fine but we are unable to get SSO working for Safari/Chrome/Edge etc.



We have found the following article:
https://docs.microsoft.com/en-us/azure/active-directory/develop/apple-sso-plugin



We have installed the Microsoft company portal app on our test device and deployed a Single-Sign On Configuration Profile to the test device and configured it as per Microsoft documentation in the above link.



We are not sure if the required custom configuration is applying correctly as the documentation states we need to add the following key pairs for it to work.



Key: browser_sso_interaction_enabled
Type: Integer
Value: 1 or 0



and



Key: browser_sso_disable_mfa
Type: Integer
Value: 1 or 0



We have done a test on mac which is Intune enrolled only and have used Intune to deploy the Single Sign On config profile and it works a treat.
Opening Safari and going to office.com automatically shows the user signed in and we can simply click on it to log on.



On our JAMF enrolled device we still get prompted for a username and password.



We are using pure Azure AD and not using kerberos.



Any advice or information would be greatly appreciated.

We have this setup and the piece I think you're missing is you'll need to setup Conditional Access and register the device with Intune through the Jamf integration.

The Mac does not need to be enrolled into Intune for the SSO extension to work, you just have to have the company portal installed and the profile properly configured and deployed to the Mac.

We were hoping not to have to configure the Conditional Access in JAMF, from what we understand the company portal simply needs to be installed on the device for the extension.



@nelsoni have you managed to get it to work without the Conditional Access? If so please could I pick your knowledge on how you have managed to get it to work, spent hours of research and testing and still been unable to get it to work.



I have attached images of my config profile setup





hobbs155, I do have the Azure SSO profile working without using conditional access. All I am doing is deploying my profile alongside the Intune company portal and that seems to be doing the job. Your profile appears to match mine.

@nelsoni thank you for you replies, I have deleted my SSO Extension profile in JAMF and re-created it again just incase there was something wrong with it. I'm still not getting it right 😞



I'm testing on Big Sur, Jamf Connect installed and appears to be working, have deployed the SSO Extension profile and then manually installed the Company Portal app, have not touched the Company Portal app after installing it.



Only profiles are the jamf connect and sso extension profile and then the microsoft auto update config, otherwise we are testing vanilla.
Was there anything in Azure that you needed to do?



I must be missing something. Please can you let me know the steps you have followed to get it working.



This is what i see when trying to log in to office.com via safari.



That screenshot looks good, you have to login at least once and that popup window is the company portal doing the brokerage between safari and Azure, once you login the company portal should pass the token to each other app that needs to authenticate.

@nelsoni on our Intune enrolled test device it just shows the user account which you have logged into the mac with, you can click on it and it will sign you straight in. We didn't need to type in an e-mail address.

From my testing and seeing deployments done by Apple themselves, there has to be at least one login performed, not sure how you got it to carry over from just an initial login from the Macs login window.

If we manage to figure it out I will let you know. Thank you for all your input is has been valuable.

@Hobbs155 Hi there,



Any updates from your side? could you figure it out?

@ali.fadavinia no we havent made much more progress on this just yet but also have not had much time to spend on it at the moment. I had contacted JAMF support and they have seen the same results as us.

Any news on this ? -

 

I've been testing this config and was able to have Zscaler take the credentials from an Intune enrolled test device. (Leveraging the JAMF\\Conditional Access Intune enrollement).

Although Safari just shows a blank screen when getting to a login page that should take AzureAD creds. 

Chrome and Outlook dont appear to be affected by the SSO config as they just show the usual AzureAD login prompts.

 

Anyone else make any progress with this config?

 

Im doing the same as in the screenshots except I am using the following for my plist.

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>AppAllowList</key>
<string>com.zscaler.Zscaler, com.apple.Safari, com.microsoft.Outlook, com.google.Chrome, com.mozilla.firefox</string>
<key>AppPrefixAllowList</key>
<string>com.microsoft.</string>
<key>Browser_SSO_Interaction_Enabled</key>
<integer>1</integer>
<key>Disable_Explicit_App_Prompt</key>
<integer>1</integer>
</dict>
</plist>

Anyone got this SSO working. Trying to get it working with chrome, but it always prompt for username password even loggin into microsoft site

I'm also having problems getting the SSO to work after following the directions listed here. https://docs.microsoft.com/en-us/azure/active-directory/develop/apple-sso-plugin.

 

From Hobbs155's screen shot, there is a Custom Configuration using the com.microsoft.CompanyPortalMac.plist. Can anybody here who has this working share their plist and advise where the file should be stored (Jamf Pro and/or end-user machine)?

 

Thank you in advanced!

According to MS chrome is not supported with SSO
