LDAP Authentication

Tip submitted by @mleneveut

To add an LDAP authentification to your JHipster application, follow these steps :

Add the dependency to spring-security-ldap. Example for gradle in build.gradle :

    compile group: 'org.springframework.security', name: 'spring-security-ldap', version: spring_security_version

Modify the SecurityConfiguration.java, method configureGlobal(AuthenticationManagerBuilder auth)

    @Inject
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

        LdapContextSource contextSource = new LdapContextSource();
        contextSource.setUrl("ldap://[IP goes here]:[port goes here]");
        contextSource.setBase("dc=mycompany,dc=com");
        contextSource.setUserDn("cn=aUserUid,dc=mycompany,dc=com");
        contextSource.setPassword("hisPassword");
        contextSource.afterPropertiesSet(); //needed otherwise you will have a NullPointerException in spring

        auth.ldapAuthentication()
        	.userSearchBase("o=myO,ou=myOu") //don't add the base
        	.userSearchFilter("(uid={0})")
        	.groupSearchBase("ou=Groups") //don't add the base
        	.groupSearchFilter("member={0}")
        	.contextSource(contextSource);
    }

Modify the SecurityUtils.java, method getCurrentUserLogin()

    } else if (authentication.getPrincipal() instanceof LdapUserDetails) {
    	LdapUserDetails ldapUser = (LdapUserDetails) authentication.getPrincipal();
    	return ldapUser.getUsername();
    }
