An allowance beyond the number of license units purchased.
Software manufacturers can allow unlicensed access (a grace condition) on their license certificates. This functionality allows users to continue using the product while you purchase and install more license certificates.
NOTE:Unlicensed access does not grant licenses. The terms and conditions of your license agreement specify how the product is to be used.
To see how a product handles unlicensed access, refer to the product-specific documentation. NetWare allows up to 3 grace connections.
Scenario: You install licenses for 100 users. The company hires 10 more employees, and you create network accounts for them. Even though 110 user accounts exist, only the first 100 users that log in can gain access to the network, until 10 more licenses are added to accommodate the 10 unlicensed users.
