Why Teams desktop client does not auto-login using ADFS?
On a domain bound machine, while opening MS Teams it does not auto-login user and shows following prompt: Tried to SSO to MS Excel and it worked on same machine and did not prompt for cred...
- Btw, maybe worth looking at https://docs.microsoft.com/en-us/office365/troubleshoot/sign-in/sign-in-issue-with-modern-auth
kpsingh Hello, without knowing much of your config, see if this can assist in any way.
'Sign in to Microsoft Teams using modern authentication'

ChristianBergstrom I followed this article as well. As they suggested, I have updated windows to latest version. Other than Teams, I'm able to auto-login to other MS Office apps such as Excel or Work etc.
However, Teams gives me windows auth prompt while it should auto-login as well.
kpsingh Hey, I'm just about to turn off my laptop. But this is a "basic authentication" prompt as far as I can tell and Teams uses modern authentication by default as well. Is this happening for all users? Please provide some additional tech details about the scenario and I will try to assist.
ChristianBergstrom Please see below for our configuration:
- We are using AD FS on prem and integrated it with O365 for SSO
- Client machines are domain bound which means they login to computer using their AD credentials
- Every Teams URL is added in trusted sites in IE (https://docs.microsoft.com/en-us/microsoftteams/troubleshoot/teams-sign-in/sign-in-loop)
- In IE, User Authentication > Logon is set to "Automatic logon with current user name and password"
Using above configuration, when basic authentication prompt shows up, it should automatically login to teams rather than user to enter credentials again.
This however works with other MS Office apps such as Excel.
I hope this helps more in understanding our issue.
