Latest update with new features is coming soon (December 2025). Most of the changes are SSO and Kerberos improvement. Find out more about each of them below.
SSO test JSON support
We improved SSO test service for better reporting, and also we added JSON test result output for URL queries with MIME type "application/json".
SSO auto-detect (ldap / kdc discovery)
Networking library updates with DNS improvements to discover LDAP and KDC servers based on local network DNS service. Important feature for other SSO features added within this release. Now, Green Screens Server can detect LDAP / KDS from local DNS network to simplify SSO configuration even more.
SSO auto-configuration
New auto-configuration feature allows to automatically configure and register Green Screens Server for MS AD environments. When a service user with defined SPN is used with auto-configuration wizard, Green Screens Server is able to automatically generate "keytab.file", server SPN and all other configs, significantly reducing SSO configuration complexity.
SSO lite support
There are situation when for various reasons, customers can't implement full Kerberos based SSO. Some older systems use custom made mechanism to achieve terminal SSO based on credentials stored in LDAP.
Thus, we added a new feature - SSO Lite based on LDAP storage. Additionally, we added JMX based plug-in system to allow custom data processors, commonly used for LDAP stored password decryption.
Module is implemented primarily to simplify migration to official Kerberos based protocols (MS AD etc.).
URL sharing flags improvements
We changed URL sharing flag from enable/disable to support multiple protection options. We added IP-Hash and Browser-Fingerprint based control mechanism. IP-Hash is less restrictive and can be useful in specific scenarios such as for SSO Lite support. IP-Hash security is relaying on SSO tokens and client IP address matching, while Browser-Fingerprint mode is very restrictive and allows generated connection URL to be used only from a browser that initiated session.
Screen sharing improvements
We made some internal optimizations for screen sharing feature making it more performant and more reliable.
