# MinIO FTP/SFTP Server

MinIO natively supports FTP/SFTP protocol, this allows any ftp/sftp client to upload and download files.

Currently supported `FTP/SFTP` operations are as follows:

| ftp-client commands | supported |
|:-------------------:|:----------|
| get                 | yes       |
| put                 | yes       |
| ls                  | yes       |
| mkdir               | yes       |
| rmdir               | yes       |

NOTE: If `etcd` is configured with `Client-to-server authentication with HTTPS client certificates` then you need to use additional envs such as `MINIO_ETCD_CLIENT_CERT` pointing to path to `etcd-client.crt` and `MINIO_ETCD_CLIENT_CERT_KEY` path to `etcd-client.key` .

### 4. Test with MinIO STS API

Once etcd is configured, **any STS configuration** will work including Client Grants, Web Identity or AD/LDAP.
