We are developing a self registration app.
Our app allows users to register for web apps and is deployed on a weblogic 10.3.5 app server. The weblogic is connected to a local ldap system.
Once the user registeres with our app we call corporate servces to generate a user id. password activation, authentication is all handled by the corporate servcies. which also has a corporate ldap that contains all users in the company.
The approach works fine for 'new users' ie users that are not present in the corporate ldap or the local ldap: users enter their details and are issued a user id which we then copy into the local ldap once the user activates their account.
The use case we're grappling with at the moment is how to handle 'existing' users that wish to register. These are users that are currently in the corporate ldap and wish to 'register' with our applications. They get rejected during the normal registration process as they already exist in the coroporate ldap.
What i'd like to do is force them to login (simply so they don't register on behalf of somone else) and once they're logged in simply copy their data into the local ldap.
The problem is even if they are successfully authenticated by the corporate service, they don't (yet exist) as far as the weblogic server is concerned. is there a way to obtain the user id that comes with the authentication token ?
The authentication method is SAML 1.1
The application is a standard Java EE servlet based webapp using the struts2 framework.
Any ideas would be much appreciated.
Within WebLogic, you can define multiple authentication providers and set them up in the order you would like the system to use. Since you are copying data over, you would have to programmatically check for the existence of the account before attempting to create it on the LDAP server.
It would be a lot simpler if you use the external LDAP server directly instead of copying the data to the internal LDAP server, letting you attempt logging the user in and creating the account only while catching the appropriate exception.

here is my specifications
Some users of my application are employees of the company and must use the Active Directory to connect.
Others are external users who are referenced in the application database.
Once authenticated, the user receives a JWT token and it's this token which gives him access (RBAC) to the services of the application.
So I have to implement an authentication system that manages three methods, LDAP, JDBC, JWT.
How can we do that with quarkus ?
With Wildfly my authentication module tries to validate the login successively on a list of realms.
A simple solution seem be to use keycloak to aggregate different providers
But I'm asked preferably to have only one executable to deploy.
So I'm looking for a standalone solution.
Thank
I'm a newbie in the LDAP + Liferay + OpenAM world, so I wonder if someone could point me in the right direction in a problem I have. In a real life environment, there are 2 LDAP servers, a OpenAM server and a Liferay application. What the customer needs is to authenticate users in Liferay against OpenAM, and OpenAM should use the LDAP servers. Problem is, the user exists only in one of the LDAP servers (it will be moved from one to the other in one point of the future). What the customer wants is:
Users must be able to authenticate independently of what LDAP contains the user.
The obtained token must be valid for both LDAP servers, as it will be used in a different service (I have no control over it) against only one of them to validate authentication.
As I said, I'm new to this world so, if the answer is too complex (I'm afraid it will be for me), maybe you could point me to books or docs that could resolve this scenario.
Thanks
You should configure LifeRay to use OpenAM for all authentications and you can configure OpenAM to use both LDAP servers (use different realms).
Details for OpenAM configuration will be in the OpenAM documentation.
As the previous answer states you should route all your authentication requests to the OpenAM server and let it validate the credentials against the right LDAP server. Using two different realms (one for each LDAP server) won't work in your case since that will require LifeRay to know where to find the user before hand. Also, sessions are linked to a specific realm.
There are multiple solutions to your problem. Here are just a couple:
Option 1
If you have control over the authentication flow. That is, if your application uses a custom UI and communicates with OpenAM via REST, you could create two different authentication module instances under a single realm (let's say two instances of the DataStore authentication module) each one pointing to a different LDAP server.
Let's call this module instances DataStore1 and DataStore2. Your application can collect the user credentials (username and password) and submit them to DataStore1. If authentication succeeds the user is already logged in. If it fails, the application can try with DataStore2.
Of course this is not ideal since you'll be making two authentication requests per login instead of just one.
Option 2
A better option (though more complicated to implement) would be creating a custom authentication module. This module can try authenticating the user against LDAP Server 1 and then try with LDAP Server 2 if the first authentication failed. Notice that with this option you don't need custom logic on the application side since it will only send a single authentication request to the OpenAM server. In fact, you can protect your application with an OpenAM Policy Agent.
Another advantage of this approach over Option 1 is that you can migrate your users behind the scenes assuming that the end goal is to migrate users from LDAP Server 1 to LDAP Server 2. If the first authentication succeeds your custom code could read the user entry from LDAP Server 1 and copy it over to LDAP Server 2.
Hope this helps you solve the problem.
After some theoretical help on the best approach for allowing a SaaS product to authenticate users against a tenant's internal Active Directory (or other LDAP) server.
The application is hosted, but a requirement exists that tenants can delegate authentication to their existing user management provider such as AD or OpenLDAP etc. Tools such as Microsoft Online's hosted exchange support corporate AD sync.
Assuming the client doesn't want to forward port 389 to their domain controller, what is the best approach for this?
After doing some research and talking to a few system admins who would be managing this, we've settled on an two options, which should satisfy most people. I'll describe them here for those who were also interested in the outcome.
Authentication Service installed in the origanisation's DMZ
If users wish to utilise authentication with an on-premises active directory server they will be required to install an agent in their DMZ and open port 443 to it. Our service will be configured to hit this service to perform authentication.
This service will sit in the DMZ and receive authentication requests from the SaaS application. The service will attempt to bind to active directory with these credentials and return a status to indicate success or failure.
In this instance the application's forms based authentication will not change, and the user will not be aware of the authentication behind the scenes.
OpenId
Similar to the first approach, a service will be installed in the client's DMZ, and port 443 will be opened. This will be an OpenId provider.
The SaaS application will be an OpenId consumer (already is for Facebook, Twitter, Google etc login).
When a user wishes to log in, the OpenId provider will be presented, asking them to enter their user name and password. This login screen would be served from the client's DMZ. The user would never enter their username or password into the SaaS application.
In this instance, the existing forms based authentication is replaced with the OpenId authentication from the service in the client's DNZ.
A third option that we're investigating is Active Directory Federated Services, but this is proprietary to Active Directory. The other two solutions support any LDAP based authentication across the internet.
Perhaps this might help…
This vendor, Stormpath, offers a service providing: user authentication, user account management, with hookups to your customers’ on-premise directories.
What about an LDAPS connection to the customer's user directory? They can firewall this off so that only your servers have access if they're concerned about it being public. Since it's SSL it's secure end to end. All you need from them is the certificate from their issuing CA (if it's not a public one). I struggled to get this working for an internal web project in the DMZ and there's a real lack of any guides online. So I wrote one up when I'd got it working:
http://pcloadletter.co.uk/2011/06/27/active-directory-authentication-using-ldaps/
Your best bet is to implement a SAML authentication for your SaaS application, and then sign up with identity providers like Okta or OneLogin. Once that's done then you can also connect it with ADFS to provide Single Sign On for your web application through Active Directory.
I'm just doing this research myself and this is what I've came across of, will have more updates once implementation is done. Hope this gives you enough keywords to do another google search
My understanding is that there are three possible solutions:
Installing something on the domain controller to capture all user changes (additions, deletions, password changes) and send updates to the remote server. Unfortunately there's no way for the website to know the initial user passwords - only new ones once they are changed.
Provide access for the web server to connect to your domain controller via LDAP/WIF/ADFS. This would probably mean opening incoming ports in the company's firewall to allow a specific IP.
Otherwise, bypass usernames/passwords and use email-based authentication instead. Users would just have to authenticate via email once every 3-6 months for each device.
I have to begin implementing this for an upcoming project and I'm seriously leaning towards option #3 for simplicity.
I have a project with the purpose of exposing multiple web applications over the internet. These applications are build using IIS/DotNet and Apache/Php.
The internet user should log-in in only one place, and then be able to access any aplication.
What are the posible solutions to this scenario? One requirement is that changes to existing applications be minimum and another is to use ActiveDirectory for user management.
I have found so far the following solutions:
use a reverse proxy (COTS product) to publish web applications to the internet, and the proxy should take care of authentication/SSO
using forms authentication and a domain wide cookie; this solutions requires changes to existing applications and manual log in in AD
create a new application using forms authentication and after user enters credentials into this application, use these credentials to send a XMLHttpRequest to another applications (this will log in the user)
use client certificates, so that when a user connects to an applications, his certificate will handle the log in process; this approach has a problem when there is more than one certificate installed in the client browser because the browser will ask the user to choose a certificate (and this will happen for every app)
I have a database with LDAP login enabled. It works fine when logging in through the PIA or when logging into app-designer through the application server.
I need to make app-designer allow me to login with 2-tier mode using LDAP authentication. Is this possible without customization?
I do not think this is possible. 2-tier logs directly into the database and more importantly, does not run the signon peoplecode that does call-outs for LDAP authentication. In fact, 2-tier is really just a Win32 app that runs no peoplecode - it isn't a peoplesoft "application." There is a user callout dll delivered with peoplesoft, and some scant documents on what you have to do to use it - but again, likely not going to meet your need. You may need to use the ldap synch online app engine job to pull in your ldap users to security tables if you want to use those login identities for 2-tier access.
The only delivered way to use LDAP Authentication for App Designer is to use connection 3-Tier through the app server. Only with the 3-Tier connection will the Signon PeopleCode be executed. With 2-Tier, there is no hook to the LDAP Server.
You could look at using the Grey Sparling Desktop Single Signon, which does integrate with App Designer and uses Windows and NTLM to grab Active Directory authentication. This would give you some degree of LDAP Authentication if you Windows machine authenticates with a domain. But it is an add-on product you would need to purchase.
Otherwise, as Epictetus mentioned, you can use the LDAP Username if you have it synced with your PeopleSoft database and use the local password stored in PSOPRDEFN.
One problem I have seen is that when using LDAP and 2 tier when you login with LDAP it somehow decrypts the password in PSOPRDEFN. The next login 2 tier by that same account throws the error cannot login please encrypt password using data movoer encrypt password *. If you encrypt that users password the same results happen following that users next LDAP login.
