Question about integrating sso with docker

[AidenZ]

hello all,

Due to business needs, I need modules to integrate sso.

But after I followed the tutorial to generate my-saml.keystore file, and made file placement and configuration changes, strange info appeared.

Prompt "SAML key store must have one alias" and "Missing SAML key for SP share".

Below is my directory structure：

May I ask if I have a configuration error or the file is in the wrong place.
