SNS 3.11.2 LTSB bug fixes
System
Multi-user authentication
Support reference 78887
After CSP (content-security-policy) directives were implemented in phases on some websites and these directives were verified by mainstream browsers, users who have SNS multi-user authentication would see a degraded display of such websites.
This issue was fixed by adding the firewall's FQDN to the list of websites allowed to use external resources for the sites in question.
Support reference 78677
After the recent implementation of a new security policy on mainstream web browsers, SNS multi-user authentication would longer function. Depending on the web browser used, the error message "Too Many Redirects" or a warning would appear in the browser’s web console.
To fix this issue, the authentication cookies that the proxy generates now contain the attributes "SameSite" and "Secure" when HTTPS is used.
When a user visits an unsecured website, i.e., one that uses HTTP, the "Secure" attribute of the cookie cannot be used. The web browser must be manually configured to enable browsing on these websites again.
