This section provides solutions for an error screen displayed when configuring SAML authentication.

Messages

No user account for that NameID found.

Cause

cybozu.cn has no user whose login name matches the NameID in the SAML response.

Solutions

• Configure your IdP so that the NameID specifies an element to identify a user.
• Ensure that the value associated with the NameID corresponds to the login name of a cybozu.cn user.

Messages

Corresponding AuthnRequest not found.

Cause

This occurs in the following cases:

• Multiple SAML requests were issued in one session.
  Example:
  • A user tried to single sign-on from multiple tabs in one Web browser.
  • After a user single signed-on, the user clicked the "Back" button of the Web browser to display the endpoint URL of cybozu.cn.
• An IdP-initiated SSO process was tried.

Solutions

• Ensure that users do not perform actions that generate multiple SAML requests in one session.
• Configure your IdP so that it can use SP-initiated SSO.

Messages

Cause

There is no SAML response in the request parameter that the IdP sent to cybozu.cn.

Solution

Invalid HTTP method. Use POST as the HTTP method.

Cause

HTTP POST Binding is not being used to send the SAML response.
