 ### Cannot read, list or access files on data lake storage
 
 If you are using Azure AD login without explicit credential, make sure that your Azure AD identity can access the files on storage. Your Azure AD identity need to have Blob Data Reader or list/read ACL permissions to access the files - see [Query fails because file cannot be opened](#query-fails-because-file-cannot-be-opened).

If you have used [SAS token](develop-storage-files-storage-access-contro.md?tabs=shared-access-signature) make sure that it has `rl` permission and that it didn't expired.
