CAL and SAL describe access under different Microsoft commercial models. A customer licensing its own Windows Server environment commonly uses Client Access Licences. A service provider may report Subscriber Access Licences under its provider agreement and include them in a monthly hosted service.
Microsoft documents RDS CALs as either Per User or Per Device and requires an activated licence server for RDS Session Host deployments after the applicable grace period. Always confirm current terms for your agreement and deployment with Microsoft or your licensing provider.
CAL belongs to the customer licensing model
Per User or Per Device RDS CALs are acquired and managed for a customer deployment under the applicable agreement. The organisation keeps entitlement evidence and operates the RD Licensing infrastructure.
SAL supports a service-provider model
A hosting provider can license access for subscribers through Microsoft’s service-provider programme. The provider reports usage and incorporates the rights into its service. Microsoft’s planning guidance describes Per User SALs as the flexible provider option.
The contract should translate the acronym
Customers do not need to administer the provider’s agreement, but they should know how many named users are included, which server and applications are covered, and how monthly additions or removals are handled.
A practical checklist
- Identify customer-owned or hosted deployment
- Ask which party reports licences
- Confirm the subscriber count
- Separate RDS from Office and SQL rights
Licensing reference: Microsoft Learn: RDS Client Access Licences and licensing Remote Desktop Session Hosts. Product terms and agreements control; confirm the current rules for your organisation.
The practical conclusion
CAL and SAL can support similar user experiences under different commercial responsibilities. Choose a provider that states the hosted entitlement clearly rather than leaving customers to infer it.
