> LDAPLoginModule does not correctly implement login method

>                 URL: https://issues.apache.org/jira/browse/KARAF-4968
>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-security
>    Affects Versions: 4.0.8
>            Reporter: Stijn Strickx
>            Assignee: Jean-Baptiste Onofré
>            Priority: Minor
>             Fix For: 4.0.9, 4.1.1
> When the LDAPLoginModule fails to authenticate a user, given the provided credentials,
the login() method will return false.
> This is incorrect behavior as explained in the JAAS Dev Guide: http://docs.oracle.com/javase/8/docs/technotes/guides/security/jaas/JAASLMDevGuide.html#login
> The login() method should throw a LoginException in that case. Returning false actually
tells the LoginContext that this LoginModule should be ignored.
> As long as the LDAPLoginModule is the only LoginModule configured within a Realm, the
resulting behavior from the LoginContext is as expected. The problem becomes apparent when
using the LDAPLoginModule as one of multiple LoginModules defined within a Realm. If, for
example, all LoginModules their flags are set to "required", a failure to login in the LDAPLoginModule
will just be ignored (while it logs a warning about invalid credentials) as long as the other
LoginModules were able to do a successful login. This is not the expected behavior since the
LDAPLoginModule is also configured to be "required".
