[SOLVED] Is it possible to authenticate with bind on ldap using the "username" in a webflux application with spring security like in php?

Is it possible to authenticate with bind on ldap using the "username" in a webflux application with spring security like in php?

I have searched on google but I always find only methods using the dn but for the login I don't have the dn and the username is not part of the dn. I also have looked into the code and the various different errors I have encountered and I have found nothing so far.

that's the log output with trace enabled when I try to login.

Solution

I found out how! I needed to use ActiveDirectoryLdapAuthenticationProvider instead of LdapAuthenticationProvider with BindAuthenticator.
