Restricting dropwizard admin page - dropwizard

Question

How to authenticate Dropwizard admin portal, so as to restrict normal users from accessing it?
Please help

Answer 1

In your config, you can set adminUsername and adminPassword under http like so:
http:
adminUsername: user1234
adminPassword: pass5678

Answer 2

For DW 0.7 my approach would be:
public class AdminConstraintSecurityHandler extends ConstraintSecurityHandler {
private static final String ADMIN_ROLE = "admin";
public AdminConstraintSecurityHandler(final String userName, final String password) {
final Constraint constraint = new Constraint(Constraint.__BASIC_AUTH, ADMIN_ROLE);
constraint.setAuthenticate(true);
constraint.setRoles(new String[]{ADMIN_ROLE});
final ConstraintMapping cm = new ConstraintMapping();
cm.setConstraint(constraint);
cm.setPathSpec("/*");
setAuthenticator(new BasicAuthenticator());
addConstraintMapping(cm);
setLoginService(new AdminMappedLoginService(userName, password, ADMIN_ROLE));
}
}
public class AdminMappedLoginService extends MappedLoginService {
public AdminMappedLoginService(final String userName, final String password, final String role) {
putUser(userName, new Password(password), new String[]{role});
}
#Override
public String getName() {
return "Hello";
}
#Override
protected UserIdentity loadUser(final String username) {
return null;
}
#Override
protected void loadUsers() throws IOException {
}
}
and using them in the way:
environment.admin().setSecurityHandler(new AdminConstraintSecurityHandler(...))

Answer 3

Newer Jetty versions do not have MappedLoginService, so #Kamil's answer no longer works. I have modified their answer to get it working as of Dropwizard 1.2.2:
public class AdminConstraintSecurityHandler extends ConstraintSecurityHandler {
private static final String ADMIN_ROLE = "admin";
public AdminConstraintSecurityHandler(final String userName, final String password) {
final Constraint constraint = new Constraint(Constraint.__BASIC_AUTH, ADMIN_ROLE);
constraint.setAuthenticate(true);
constraint.setRoles(new String[]{ADMIN_ROLE});
final ConstraintMapping cm = new ConstraintMapping();
cm.setConstraint(constraint);
cm.setPathSpec("/*");
setAuthenticator(new BasicAuthenticator());
addConstraintMapping(cm);
setLoginService(new AdminLoginService(userName, password));
}
public class AdminLoginService extends AbstractLoginService {
private final UserPrincipal adminPrincipal;
private final String adminUserName;
public AdminLoginService(final String userName, final String password) {
this.adminUserName = Objects.requireNonNull(userName);
this.adminPrincipal = new UserPrincipal(userName, new Password(Objects.requireNonNull(password)));
}
#Override
protected String[] loadRoleInfo(final UserPrincipal principal) {
if (adminUserName.equals(principal.getName())) {
return new String[]{ADMIN_ROLE};
}
return new String[0];
}
#Override
protected UserPrincipal loadUserInfo(final String userName) {
return adminUserName.equals(userName) ? adminPrincipal : null;
}
}
}
