Selection of the License Manager By the Protected Application
This section describes how a protected application selects a License Manager when more than one type of Sentinel LDK License Manager is available to the protected application.
Selection of License Manager Under Windows
On a Windows platform, two or more types of License Managers may be available to a protected application. The application selects the License Manager based on the type and location of the protection key that contains the required license. This section describes the process by which the License Manager that will directly access the protection key is selected.
The Integrated LM is always present in a protected application. The External LM is optionally present also. One of the two is always selected to directly access a local protection key or to hand off access requests to a local or remote Admin LM.
The License Managers to directly and indirectly access the protection key are selected as follows:
1.The Integrated LM is selected if the External LM is missing or is an older version. Otherwise, the External LM is selected.
2. A local SL UserMode key is always directly accessed by the selected Integrated/External LM.
3.A local Sentinel HL (Driverless configuration) key is directly accessed by the selected Integrated/External LM if a local Admin LM is absent or is an older version than the Integrated/External LM. Otherwise, access requests are forwarded to the local Admin LM.
NOTE If all of the following are true:
>A Network Seat license is installed on an HL (Driverless configuration) key.
>The HL key is located on the same machine as a protected application that consumes a network seat.
>The local Admin LM is an older version than the Integrated/External LM.
The access attempt may fail with the error HASP_OLD_LM.
To ensure full functionality, Thales recommends that you install the latest RTE whenever you update the deployed Integrated/External LM.
4.Access requests for other types of local protection keys are always forwarded to the local Admin LM.
5.When the protection key (of a type that supports network operation) is on a remote machine, the selected Integrated/External LM handles communication directly with the Admin LM on the remote machine, even if a local Admin LM exists. However, if a local Admin LM exists and is active, the Integrated/External LM retrieves the list of license server machines (if such a list exists) from the local Admin LM.
The following diagram shows a graphical representation of the process by which the License Manager to directly access the protection key is selected.
Legend:
The External LM is selected unless the Integrated LM is a more recent version than the External LM or unless the External LM is not present. | |
For the Sentinel HL (Driverless configuration) key: The key is directly accessed by the Admin LM unless the selected Integrated/External LM is a more recent version than the Admin LM, or unless the Admin LM is not present. |
The following table provides a summary of which License Manager is selected to directly access each type of protection key. Note that the Admin LM and External LM are not necessarily present in all cases.
Type of protection key that contains the required license | Location of the key | License Manager selection priority (from highest to lowest) |
---|---|---|
Sentinel HL (Driverless configuration) key | Local |
1.Admin LM (if the Admin LM is the same or a more recent version than the External LM and the Integrated LM) 2.External LM (if the External LM is the same or a more recent version than the Integrated LM) 3.Integrated LM |
Sentinel HL (HASP configuration) or HASP HL key | Local | Admin LM |
SL Legacy key or SL AdminMode key | Local | Admin LM |
SL UserMode key | Local |
1.External LM (if the External LM is the same or a more recent version than the Integrated LM) 2.Integrated LM |
A protection key that supports concurrency | Remote | (Remote) Admin LM |
Selection of License Manager for Protected Data Files Under Windows
Selection of the License Manager for data files with licensing protection is determined by the location of the protected application or the Web browser that is used to access the data files, and not by the location of the data files. Therefore, the process for selection of the License Manager is the same as for any other protected application on a Windows platform.
Selection of License Manager Under Mac
On Mac platforms, only the Admin LM is supported. For a local protection key, all access requests are handled by the local Admin LM. For a remote protection key, the local Admin LM passes the access request to the Admin LM on the remote machine where the protection key is located.
Selection of License Manager Under Linux
On Linux Intel and ARM platforms, selection of the License Manager is identical to the process for Windows platforms, with one exception: the External LM is not supported and therefore cannot be selected.
Selection of License Manager Under Android
On Android platforms, only the Integrated LM is supported. The Integrated LM handles all access requests for a local protection key.
The Integrated LM can also consume a network seat from the Admin LM on a remote machine with a protection key that supports concurrency.
