I understand that AD authentication is possible with the source code of the following URL, but I would like to output the user and authentication URL in the log.

• Auth URL

https://login.microsoftonline.com/{tenantID}/oauth2/v2.0/authorize?response_type=code&client_id={clinet_id}

• Login UserId

user001@tenant.onmicrosoft.com

Redirects are unknown, but user IDs can be output in the following format

    @GetMapping("Adimn")
    public ModelAndView Adimn(HttpServletRequest request) {
    
        try {
            String userId = request.getUserPrincipal().getName();   
            log.info(userId);

        return new ModelAndView("redirect:" + "/index");
    }
