为什么shibboleth IdP idp-metadata.xml为SOAP推荐8443？

Question

在2.4.0 Shibboleth Identity Server的install.sh之后，将创建idp-metadata.xml文件。为什么会这样呢？使用标准的HTTPS/443端口不够安全吗？

    <ArtifactResolutionService Binding="urn:oasis:names:tc:SAML:1.0:bindings:SOAP-binding" Location="https://idp.example.com:8443/idp/profile/SAML1/SOAP/ArtifactResolution" index="1"/>
    <ArtifactResolutionService Binding="urn:oasis:names:tc:SAML:2.0:bindings:SOAP" Location="https://idp.example.com:8443/idp/profile/SAML2/SOAP/ArtifactResolution" index="2"/>
    <SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:SOAP" Location="https://idp.example.com:8443/idp/profile/SAML2/SOAP/SLO" />
    <AttributeService Binding="urn:oasis:names:tc:SAML:1.0:bindings:SOAP-binding" Location="https://idp.example.com:8443/idp/profile/SAML1/SOAP/AttributeQuery"/>
    <AttributeService Binding="urn:oasis:names:tc:SAML:2.0:bindings:SOAP" Location="https://idp.example.com:8443/idp/profile/SAML2/SOAP/AttributeQuery"/>

谢谢,

使用Linux时，像"tomcat“这样的非特权用户无法绑定到1024以下的端口。Apache和Nginx等前端负载均衡器以root用户身份启动，以绑定到端口80和端口443等特权端口。常见的设置包括在8080或8443等非特权端口上运行Tomcat实例，然后通过Apache或Nginx代理该端口。
