I am using Jenkins version 1.638, and i do the configure global security for using LDAP as my access control, i setup the load serer and its manager DN/manager password, it looks like already working, because when i do the save, there is no error in GUI.

how ever, i get error "Invalid login information. Please try again." when i try to login with my AD access, i try both username like 'abc' and domain\username like 'AP\abc' but both failed.

Also i Failed to connect to https://www.google.com.hk/ (code 407). when i use plugin manager-->HTTP proxy configuration, error logs are as below:
