Please add the possibility to stack several authentication providers.
Hi. Is there a specific reason you are requesting this?
This has been discussed before. It's not hard to combine two authentication modules, but doing it in a generic way is tricky, especially when hashed authentication mechanisms are involved.
yes, I would like to have one authentication provider to be tried first (e.g. LDAP) and if the authentication there fails, to try the credentials with another provider (e.g. mod_auth_external).
