Let's use the tools provided by **FastAPI** to handle security.

## How it looks

Let's first just use the code and see how it works, and then we'll come back to understand what's happening.

## Create `main.py`

Copy the example in a file `main.py`:

//// tab | Python 3.9+

```Python
{!> ../../docs_src/security/tutorial001_an_py39.py!}
```

////

	if err = validateConfig(ctx, cfg, subSys); err != nil {

		var validationErr ldap.Validation
		if errors.As(err, &validationErr) {
			// If we got an LDAP validation error, we need to send appropriate
			// error message back to client (likely mc).
			writeCustomErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrAdminConfigLDAPValidation),
				validationErr.FormatError(), r.URL)
			return
		}
