Server Login addresses the requirement for an application to obtain access to Entrust credentials without manual authentication. Server Login is designed for computers, usually servers, which run Entrust applications as services or as background applications. These computers, running 24 hours a day, seven days a week, do not have a user continuously present and are often in a physically secure area with restricted access. Using server login, Entrust-ready services, or background processes can start without operator intervention.

See Server login samples for a complete example.

Installing the server login library

Depending on the operating system of your computer, you would need one of the following login libraries distributed in the etjava_90_lib.zip file.

OS	Library path in etjava_90_lib.zip	Library configuration
Windows	etjava/lib/win/x64/UALJNI_64.dll	Move this file to the `%windir%\system32` folder on your computer.
Linux	etjava/lib/linux/X86_64/libualjni_64.so	Move this file to the `LD_LIBRARY_PATH` of your computer.

Reading credentials

Create a credential reader – for example, to read an Entrust profile.

com.entrust.toolkit.credentials.CredentialReader credReader = new FilenameProfileReader(<epf_file_path>);

Instantiate the credential reader.

com.entrust.toolkit.credentials.UALCredentialReader reader = new UALCredentialReader(credReader, new FileInputStream(<ual_file_path>));

Creating a user

Create a user object.

com.entrust.toolkit.User user = new User();

Logging the user

This use case requires no password; login the user with the null password.

user.login(reader, null);
