I implemented "express-ntlm" on my NodeJS server for to provide SSO login. It run well with Chrome: user's login and password are validated by the navigator... But with Firefox or Edge, it seems there is no check: you can enter any user login and a wrong password, but nothing is check, and these identities are send directly to the server.
How to force Firefox and Edge to check these identities ? Or, do I have to check these identities with a LDAP on the server ? (but the NTLM package doesn't provide the password...)
