Before creating a Workspace ONE Access directory, review the User Attributes page and specify the user attributes to sync to Workspace ONE Access. You can select which attributes are required. You can also add custom attributes.
When you configure the User Attributes page before any directory is created, you can change default attributes from required to not required, mark attributes as required, and add custom attributes.
After a directory is created, you can change a required attribute not to be required, and you can add and delete custom attributes. You cannot change an attribute to be a required attribute.
