Outra grande funcionalidade necessária pelas APIs é a validação de dados, garantindo que os dados são válidos, dados certos parâmetros. Por exemplo, que algum campo seja `int`, e não alguma string aleatória. Isso é especialmente útil para dados de entrada.

	TotalRefreshFailures            uint64

	sync.Mutex

	iamRefreshInterval time.Duration

	LDAPConfig   xldap.Config  // only valid if usersSysType is LDAPUsers
	OpenIDConfig openid.Config // only valid if OpenID is configured
	STSTLSConfig xtls.Config   // only valid if STS TLS is configured

	usersSysType UsersSysType

	rolesMap map[arn.ARN]string

	// Persistence layer for IAM subsystem

     * @param data the data to write

    protected void write(final String path, final byte[] data) {
        validateFilePath(path);
        LdiFileUtil.write(path, data);
    }

    /**
     * Validates the file path.
     *
     * @param path the file path to validate

#### Sobre `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` significa:

*Pasa las claves y valores de `user_dict` directamente como argumentos clave-valor, equivalente a:*

```Python
UserInDB(
    username = user_dict["username"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

        assertEquals("deadbeef", blob.toString(), "toString() should reflect underlying content");
        assertEquals(data.hashCode(), blob.hashCode(), "hashCode should equal the array's hashCode");
    }

    // Validates equals() returns true for same-sized, equal-content blobs
    @Test
    @DisplayName("equals: identical content and size -> true")
    void equals_identicalContent_true() {
        // Arrange

	}

	claims["exp"] = time.Now().UTC().Add(defaultExpiryDuration).Unix() // update with new expiry.
	return nil
}

const (
	audClaim = "aud"
	azpClaim = "azp"
)

// Validate - validates the id_token.
func (r *Config) Validate(ctx context.Context, arn arn.ARN, token, accessToken, dsecs string, claims map[string]any) error {
	jp := new(jwtgo.Parser)
	jp.ValidMethods = []string{
		"RS256", "RS384", "RS512",

        } catch (Exception e) {
            context.invalidate();
            throw new CIFSException("Failed to update preauth integrity hash for session " + sessionId, e);
        }
    }

    /**
     * Validates the preauth integrity for completed negotiation.
     *
     * @param sessionId the session identifier
     * @param expectedHash the expected final hash
     * @return true if validation passes

### Document Language Detection

During crawling and indexing, Fess:

1. Detects language from document content using Apache Tika
2. Validates against `supported.languages` list
3. Creates language-specific fields (e.g., `content_ja`, `title_en`, `content_sv`)
4. Applies language-specific analyzers for better search results

Configured in `fess_config.properties`:
