Package org.springframework.security.web.authentication.preauth.x509

Class SubjectDnX509PrincipalExtractor

  • All Implemented Interfaces:
    org.springframework.beans.factory.Aware, org.springframework.context.MessageSourceAware, X509PrincipalExtractor
    public class SubjectDnX509PrincipalExtractor
extends java.lang.Object
implements X509PrincipalExtractor, org.springframework.context.MessageSourceAware
    Obtains the principal from a certificate using a regular expression match against the Subject (as returned by a call to X509Certificate.getSubjectDN()).

    The regular expression should contain a single group; for example the default expression "CN=(.*?)(?:,|$)" matches the common name field. So "CN=Jimi Hendrix, OU=..." will give a user name of "Jimi Hendrix".

    The matches are case insensitive. So "emailAddress=(.*?)," will match "[email protected], CN=..." giving a user name "[email protected]"
