I frequently refer to the Official Single-Sign-On post for SSO documentation. I just noticed, however, that the reference implementation has a few accessors that aren’t mentioned in that post (notably avatar_force_update, title, and groups). Would it be possible to update that post to include descriptions of these fields?
It is a wiki 
feel free to give it a shot!
no way! Here goes nothing!
That was easy enough. Thanks @sam!
I inspected discourse code base and added some notes about groups and the discourse option called sso overrides groups based on what I learned from that.
Perhaps someone could verify I got it right? Official Single-Sign-On for Discourse (sso)
Edit seems fine, thanks Erik.
我一直在努力解决这个实现问题，首先想感谢你们对 SSO 功能的文档记录！没有这些文档，我根本无法完成这项工作！
不过，我刚才用全新测试观察到的行为与文档描述并不完全一致。当指定了“SSO 覆盖组”选项时，add_groups 参数并不会添加列出的组，但 groups 参数却能正确定义组成员关系。
而当未指定“SSO 覆盖组”选项时，add_groups 可以正常工作，但 groups 参数却无法生效。
此外，我还发现以逗号分隔的组列表对逗号周围（至少是逗号后）的空格不兼容。据我回忆，如果存在空格，系统只会识别第一个组。
SSO 文档非常优秀，帮助我成功完成了 SSO 配置。然而，现在我需要在有效载荷中包含自定义字段数据，不幸的是，文档中（位于高级功能下）的链接指向了一个错误页面。如果有人能指引我正确的方向，我很乐意更新文档。
