How to log failed logins?

[Eric Wedaa]

That's (more or less) what I need.  But how do I do that?  I guess I can parse the files to get the IP address from it somehow or another.

Thanks!

        Apologies in advance if I'm misunderstanding the request; here are examples of what I log:
Bare fact of failed LDAP authN at INFO level:INFO [edu.vt.middleware.ldap.jaas.JaasAuthenticator:180] - Authentication failed for dn: uid=••••••,dc=alaska,dc=eduFurther details (LDAP error message) at DEBUG level:
 DEBUG [edu.vt.middleware.ldap.jaas.LdapLoginModule:136] - Authentication failed
javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials]

 And I'm just telling you that the old IdP doesn't do that, only the underlying authentication components do.
 
 If you want to *know* the situation, you go to the actual back-end. LDAP, Kerberos, AD, whatever. Their logs are the ones you really want.
 
 If you want to get the answer on the IdP side in V2, you are relying on the libraries that are calling those back-ends, and that's not a single answer. If you're doing LDAP with the provided code, that's the vt-ldap code, so that is the logging you're looking for, you just used the wrong category I guess. I don't know the correct one offhand, but I log all of the vt-ldap categories on INFO, and I don't think you'll find that very noisy.
