我正在尝试实施 SAML2 SSO，但收到错误saml2.sigver.SignatureError: Signature missing for response。我正在使用djangosaml2，反过来使用pysaml2。寻找签名时似乎遇到了问题：https://github.com/IdentityPython/pysaml2/blob/master/src/saml2/sigver.py#L1648
看起来它正在尝试在响应属性中查找签名，但是我的 IDP 在响应属性中没有返回签名，但是可以在响应中找到签名作为其自己的元素ns2:Signature。
我是否应该要求 IDP 提供不同的响应，或者我是否缺少配置选项？
