Public bug reported: Bug Description copied from : https://bugs.launchpad.net/keystone/+bug/1577666
The following error occurs when a user tries to login using Horizon Single Sign-On feature after the Idp authenticates the user and sends SAML assertion successfully : {"error": {"message": "An unexpected error prevented the server from fulfilling your request: [Errno 2] No such file or directory: '/etc/keystone/sso_callback_template.html' (Disable debug mode to suppress these details.)", "code": 500, "title": "Internal Server Error"}} I reproduced the above error while trying to configure Keystone for Federation taking TestShib.org as Idp and Keystone as SP. I am using Security Assertion Markup Language(SAML) for configuring Keystone for federation. The above error got fixed when I copied the sso_callback_template.html file to /etc/keystone directory. cp /opt/stack/keystone/etc/sso_callback_template.html /etc/keystone/ I would recommend to add one more point(5) under Keystone changes as follows: 5. Copy the sso_callback_template.html file to /etc/keystone/ directory: cp /opt/stack/keystone/etc/sso_callback_template.html /etc/keystone/ in the following documentation(Setup Web Single Sign-On (SSO): http://docs.openstack.org/developer/keystone/federation/websso.html ** Affects: keystone (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1578102 Title: Error: No such file or directory: '/etc/keystone/sso_callback_template.html' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keystone/+bug/1578102/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
