What problem did you meet?

Logto cannot be used directly for authentication of services such as OpenVPN and Squid.

Describe what you'd like Logto to have

It looks like Logto supports getting user information and verifying their passwords via the API. Is it possible to integrate an LDAP server just to verify that the username and password provided by the user match? This way, logto can be easily used with email servers, etc.
I know it would be difficult to get logto to get data from an LDAP server because they have different architectures. But I just hope that logto can provide a read-only LDAP interface internally without having to support getting changes through LDAP. Just like Casdoor（https://casdoor.org/docs/ldap/ldapserver/）.
I believe this will greatly improve Logto's integration capabilities.
