Checking to see if a user has a licence for a managed package

Question

So I'm aware that there is a method on UserInfo called isCurrentUserLicensed which lets you check if the user running the code has a licence for a namespace that you specify, i.e. for a particular managed package.

What I want to know is whether there is a way I can test to see if some other user (assume I have their ID) has a licence for a particular package. Has anybody found a way to do this?

Answer 1

This is possible by querying on the UserPackageLicense object, available as of Summer 14, as described in my answer to this post:

Get the list of users licensed for a managed package

private static boolean IsUserLicensedForPackage(
    String userId, String packageNamespace
) {
   return [
       SELECT count() 
       FROM UserPackageLicense 
       WHERE PackageLicense.NamespacePrefix = :packageNamespace 
       AND UserId = :userId limit 1
   ]==1;
}

User u = [select Id from User where Name = 'Grace Hopper' limit 1];

System.debug('Does Grace have a license? ' +
    IsUserLicensedForPackage(u.Id,'skuid') ? 'Yes!' : 'No :('
);

Answer 2

I know of no inbuilt way to do this (Although my employer is absolutely desperate for it).

The way that we track if a user is licensed for our managed package is whether or not they have one of our permission sets assigned to them.

However there is one enormous caveat. If the license for the managed package is revoked, the permission set remains assigned to the user. This is a significant drawback and can result in false positives, but short of a screen scraping solution it's all we've got.

There is an idea on the idea exchange that is close to what you are trying to achieve.
