• I have confirmed that there is currently no similar issue

• I have fully browsed the project README and project documentation and did not find a solution
• I understand and am willing to follow up on this issue, assist in testing and provide feedback
• I will ask questions in a polite and respectful manner and shall not use uncivilized language (the same applies to everyone who posts comments here, those who do not comply will be blocked)
• I understand and agree with the above content, and understand that project maintainers have limited energy. Issues that do not follow the rules may be ignored or closed directly

Function description
I hope that the commercial version will add a single sign-in method like Casdoor: [https://github.com/casdoor/casdoor](https://github.com/ casdoor/casdoor), which is convenient for enterprises to use for unified authentication.

After taking a look, Casdoor is similar to OAuth inside OAuth? Is it equivalent to building the Casdoor platform itself as an OAuth? In this case, I can't integrate

是的，他本身是有账号管理的（方便企业统一管理账户信息），但是可以通过SSO 或者 OIDC 进行链接，以三方登录的方式实现（类似于微信登录）：
