Error Issue Solution
Other When IAM Identity Center creates a SAML Assertion for a user, it uses the value of the 'email' field (if they are present) from the connected directory to populate the 'Email' in the SAML assertion. Many service providers expect these attributes to contain the user’s email address. By default your directory is configured to send 'windowsUPN' in both fields. Your directory may be configured to contain the users email in the 'Email' attribute instead. If so, you may need to change this in your Connected directory settings.
