You must be a freshman. I have encountered the same problem. First, you have to log on to campus websites (such as libraries and laboratories). The login account and password of the system are campus card account and inquiry password respectively. The user's campus card account number is the last six digits of the campus card number. For example, the account number of P 1 100 123 is 123, and the account number of p 000 123 is123. After logging in, go to the all-in-one card service center to change the login password. When you go back, you can log in successfully with the intranet address/Dana-Na/auth/URL _ default/welcome.cgi, hehe.
