Applies To
8x8 Applications
Microsoft Azure
Single Sign-On
Resolution
To resolve this issue:
Navigate to 8x8 Admin Console.
Click on Home > Identity and Security.
Delete the currently-applied URL in Single Sign-On Integration(SSO) > Sign-out page URL. This is typically the same URL as the Sign-in page URL.
Add the following URL in its place: https://login.microsoftonline.com/common/wsfederation?wa=wsignout1.0
Click Save to complete the change.
Test your logout functionality to confirm the fix.
Cause
This issue can occur with 8x8 applications when both of the following apply:
Single Sign-On of 8x8 applications has been configured in both 8x8 Admin Console > Identity and Security and Microsoft Azure.
The tenant-specific (Microsoft-suggested) Azure SSO Logout URL has been applied to the 8x8 SSO configuration in 8x8 Admin Console.
