If you want to implement a multi-user environment based on Microsoft Windows RDS, Microsoft and we recommend “per user” licensing for the Microsoft RDS. A valid Microsoft access license (CAL or SAL) is also required per accessing user. Either Microsoft RDS CALs with active “Software Assurance” contracts have already been purchased for the accessing users or the accessing users can be licensed on a monthly basis using Microsoft RDS SALs. RDS-SAL licenses cost EUR 6.00 per user and month plus VAT and can be purchased together with our oneclick™ app licenses – in this case the licensing for accessing users is automatically compliant with the Microsoft license terms and conditions and the purchase of RDS-CAL incl. active “Software Assurance” contract can be skipped.
