# Define an SSO User Mapping

You can manually define a single-sign on (SSO) user mapping between a user in the Environment Hub and a user in a member org. Before you define a user mapping, enable SSO in the hub member org.

## Before You Begin

|User Permissions Needed| |
|-----------------------|--|
|To set up and configure the Environment Hub:|Manage Environment Hub|

User mappings can be many-to-one but not one-to-many. In other words, you can associate multiple users in the Environment Hub to one user in a member org. For example, if you wanted members of your QA team to log in to a test org as the same user, you could define user mappings.

## Steps

1.  Log in to the Environment Hub, and then select a member org. If you don’t see any member orgs, check your list view.

2.  Go to the Single Sign-On User Mappings related list, and then select **New SSO User Mapping**.

3.  Enter the username of the user that you want to map in the member org, and then look up a user in the Environment Hub.

4.  Select **Save**.
