This commit fixes x509 authentication when using nginx as web server.
X509AuthenticationListener depends on the SSL_CLIENT_S_DN_Email field being set.
As is, this field is specific to Apache and cannot be provided by nginx. nginx
can provide the DN of the certificate in SSL_CLIENT_S_DN. If the email field is
not set, the listener tries to extract the email address from the DN.

Some phpdoc are wrong in the Config component after the PR #10701 was merged.
eg:
    IntegerNode was changed to intNode
    BooleanNodeDefinition was changed to boolNodeDefinition
