You can customize identity conversion rules based on your service requirements. If you do not configure identity conversion rules, the username of the federated user on the cloud platform is <strong id="iam_08_0004__en-us_topic_0272447058_b12497113518215">FederationUser</strong> by default, and the federated user can only access the cloud platform by default.</p>

Ensure that user groups have been created. For details about how to create a user group, see <a href="en-us_topic_0046611269.html">Creating a User Group and Assigning Permissions</a>.</li></ul>
