 # You will need to replace <ORG_NAME> and <SAML Name ID> with the actual GitHub organization name and the SAML `NameID` value that you're searching stored external identities for in the GitHub organization. 
 # For GitHub Enterprise Cloud organizations that have SAML configured at the organization level, this will query the stored SAML `nameId` and SCIM `userName` external identity values in the GitHub organization, and if one is found that matches the value specified for `<SAML Name ID>`, it will print out the SAML `nameId` and GitHub username for that stored external identity.

 # This query will not print out a user username (`login`) value if there is not a GitHub user account linked to this SAML identity. 
 # Pagination shouldn't be needed since there shouldn't be multiple entries in the organization that have the same SAML `NameID` or SCIM `userName`. However, for more information on pagination. There is also an example of pagination in simple-pagination-example.graphql.
