I configured single sign on SAML between mattermost and keycloak but we have problem during single logout. When I called url for logout I get response from mattermost api that logout was success. But after open mattermost url for login I can login without username and password. When I close and open browser after logout everything is fine and keycloak ask for username and password. I need scenario for keycloak ask user and pass without closing browser after logout.
During logout process firstly I called url defined in keycloak documentation
https://keycloak-app/auth/realms/master/protocol/openid-connect/logout?redirect_uri=https://mattermost-app/login/sso/saml
I get response from mattermost api but I'm not redirect to login site. I must go to login manually
{"status":"OK"}
Configuration in keycloak:
Force Post binding: Enable
Front Channel Logout: Enable
Logout Service POST biding URL: https//:mattermost-app/api/v4/users/logout
Logout Service Redirect Binding URL: https://mattermost-app/login/sso/saml
I hope I wrote enough information for explain my problem. Thank for help
