描述

### problem

Within the portal, SAML accounts operate normally without any issues until the logout process. Currently, a loop is generated during sign-out, and the web browser session is never properly terminated. As a result, users must either clear their browser cache or open a new session in incognito/private mode to log in again.

### versions

ACS. 4.22.x

### The steps to reproduce the bug

1. Enable Saml integration with Cloudstack

2. Login as saml user

Check the session key

2. Execute the following api

https://cloudstack.apache.org/api/apidocs-4.22/apis/samlSlo.html

https://your-mgmt-serverip:8080/client/api?command=samlSlo,

- If your IdP exposes its own Single Logout trigger, use that (it should redirect the browser to CloudStack's samlSlo URL).

Inspect the response in the Network tab
- Find the command=samlSlo request.
- Check its response headers: status 302, a Location header pointing at the redirect target — but no Set-Cookie header clearing JSESSIONID/userid/sessionkey (i.e. no Max-Age=0 entries for those names).

研究方向

先查看連結的已合併 pull request #14017,接著重現 issue 中描述的 samlSlo API 流程,並在瀏覽器的 Network 分頁中檢查重新導向回應。當 logout 回應清除列出的工作階段 Cookie,且後續登入無需清除瀏覽器資料即可成功時,即表示完成。
