Where can I see the user after creating an End User via API?

Hello,

I'm having trouble seeing the end user in MediaSpace when it's created via an API call. I'd appreciate any pointers!

Here's what I'm doing to create an End User:

KalturaUser newKalturaUser = new KalturaUser();
newKalturaUser.id = userId;
newKalturaUser.firstName = firstName;
newKalturaUser.lastName = lastName;
newKalturaUser.screenName = userId;
newKalturaUser.fullName = firstName + " "+ lastName;
client.getUserService().add(newKalturaUser);

This seems to add an end user, because when I list users or get user
client.getUserService().list();
or
client.getUserService().get(userId);
user is there.

However, when I go to the Manage Users page (http://[instanceId].mediaspace.kaltura.com/admin/user-list), I don't see the user I just added. I can go through the UI to add a new user and the user will show up in the UI and via the API "getUser"/"listUser" call.

Also, I do not expect this end user to show up in the KMC user list, but in KMC UI, we're able to assign a content to this user that we can't even see via UI. So we just can't see this user anywhere, and can't update or delete this user unless we go through the API call.

(And just a note, using KalturaAdminUser object instead of KalturaUser works just fine when we want to add an admin user to KMC - the admin user shows up in the KMC user list.)

So what do I need to do in addition to just adding an end user for it to show up in the Manage Users page in MediaSpace?

Thank you,
Kumi
