求助， Nginx 反向代理 Exchange（IIS）遇到的问题。

我想在两台 Exchange2016 前加入 nignx （ Tengine ）做反向代理和负载均衡。 现在遇到的问题是：OWA 可以正常访问，但是 Outlook （ Mac 端）配置时一直弹窗提示输入用户名和密码，正确输入后说用户名和密码错误。Windows 端也是类似的错误。

配置如下： #mail.test.com.conf

upstream test { server xx.xx.xx.xx; server xx.xx.xx.xx; } server { listen 443 ssl; server_name mail.test.com autodiscover.test.com; include rules/ssl.conf; # 设置了服务器证书 location / { index index.php; proxy_pass http://test/; proxy_http_version 1.1; proxy_set_header Connection ""; proxy_next_upstream error timeout; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_ignore_client_abort on; } } server { listen 80; server_name mail.test.com autodiscover.test.com; return 301 https://$host$request_uri; } 

#nginx.conf

worker_processes auto; worker_cpu_affinity auto; events { worker_connections 65535; use epoll; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 128; sendfile on; tcp_nopush on; tcp_nodelay on; gatekeeper_module on; fastcgi_connect_timeout 5; fastcgi_send_timeout 10; fastcgi_read_timeout 10; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; keepalive_timeout 60; keepalive_requests 1024; client_header_buffer_size 4k; large_client_header_buffers 4 32k; client_max_body_size 10m; client_body_buffer_size 512k; client_body_timeout 30; client_header_timeout 10; send_timeout 240; proxy_connect_timeout 10s; proxy_send_timeout 50s; proxy_read_timeout 60s; proxy_buffers 64 8k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 64k; proxy_redirect off; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; gzip_types text/plain application/x-Javascript text/css text/xml application/xml+css application/json text/Javascript; gzip_vary on; log_format main '$server_addr\t$host\t' '$remote_addr\t$remote_user\t$http_x_forwarded_for\t' '$time_local\t' '$scheme\t$request\t' '*#06#$status*#06#\t$upstream_status\t' '$request_time\t$upstream_addr\t$upstream_response_time\t' '$request_length\t$bytes_sent\t' '$operationid\t$HTTP_DIDI_HEADER_SPANID\t' '$http_referer\t$http_cookie\t$http_user_agent\t' '$limit_rate'; access_log logs/access.log main; set_real_ip_from 10.0.0.0/8; set_real_ip_from 100.64.0.0/10; real_ip_header X-Real-IP; include conf.d/*.conf; include sites-enabled/*; } 

另：当 Exchange 中的认证方式从 Windows 认证改成 Basic 认证后，MAC 端 Outlook 配置成功了，但是 Win 端还不行。
