How to allow redirecting to ldap_login with more custom parameters? #140

Closed hzung closed 3 years ago

hzung commented 3 years ago

When I try to redirect the ldap_login to a new error URL such as /ldap_login?error_captcha. The server keeps automatically redirect this URL to /ldap_login. The system seems to allow only redirect to /ldap_login?error.

Is there anyone who knows where to control this redirection rule?

I try to find all possible places I can think of, but no luck. Thank you so much.

When LDAP is enabled, the page used for handling logins is defined at https://github.com/swri-robotics/bag-database/blob/master/src/main/java/com/github/swrirobotics/config/SecurityConfig.java#L159 . Any unauthenticated request will be directed to that page.

The controller that handles requests to ldap_login is very simple: https://github.com/swri-robotics/bag-database/blob/master/src/main/java/com/github/swrirobotics/ldap/LdapLoginController.java

All it does is use the MVC view ldap/ldap_login. The HTML template for that view is here: https://github.com/swri-robotics/bag-database/blob/master/src/main/webapp/WEB-INF/views/ldap/ldap_login.html

Requesting ldap_login?error_captcha should result in a parameter named error_captcha being set in that view, which you could handle similar to the existing error and logout parameters to change how the page appears.
