We have a Siteminder running in our organization and I want to use Kerberos to authenticate users.
The setup is like this:
Our appserver has siteminder agent that can authenticate users, agent connects to Siteminder, siteminder connects to active directory.
My question is this - what do I need to do on my appserver in order to be able to use Kerberos to authenticate users.
I might accept a good guide to how to do it as an answer.
This guide says you need to set your service account to system and set authentication in IIS to be anonymous only. This sounded totally crazy to me at first, but as you read on they explain how the additional ISAPI dll they have you add will intercept the SiteMinder auth and should pass the authentication through. Not sure if it's actually kerberos or not...

I have an Apache server where users authenticate to a website through Kerberos/GSSAPI (mod_auth_gssapi). In the event of a user attempting to visit the site externally (not available on the network ldap server), I would like to fallback to SAML authentication (mod_auth_mellon), but am having trouble figuring out if this is even possible. I am managing the config for this in httpd.conf. Both work independently of each other.
I have seen a number of suggestions and threads, but nothing seems to work for me. The Mellon module github page recommends using a config to preemptively check for credentials, but in my case, credentials do not exist yet, and any IF statements executed would happen before I can retrieve them.
Essentially, I would like to do this:
User visits site
Apache checks for LDAP username credentials through Kerberos/GSSAPI
If Kerberos credentials do not exist, try to mauthenticate through SAML/Mellon
I do not know ahead of time which users' information will be available in my local AD server or attempting to access externally.
I would like to keep this on the Apache side if possible, though I may have to relent and run SimpleSAML or something after Apache authenticates.
I am expecting to have an authentication fallback of Kerberos to SAML in my Apache config. Currently, Apache defaults to the last authentication method listed in the config file. I would like an either/or scenario, depending on whether the first authentication method is able to obtain a valid user.
Any ideas, thoughts, solutions, criticisms appreciated.
I would like to authenticate automatically to wso2 IS with a kerberos ticket obtained from kerberos authentication (using Windows server 2K12 as KDC).
I didn't find any information related to kerberos authentication on WSO2 documentation. The list of all handled are defined here : https://docs.wso2.com/display/IS460/Managing+the+Identity+Server.
The one that is closer to kerberos authentication is the "integrated windows authentication".
Have I missed the documentation page or is it impossible to authenticate with this methods ?
I think I should go with https://docs.wso2.com/display/IS500/Creating+Custom+Authenticators but not sure about it.
Thanks.
I think, you basally need the window authentication? It means once you login to windows machine, you can access the service protected with Identity Server by default. In IS 5.0.0 version, you can find IWA authentication that can be used for external application authentication and login to WSO2IS management console. There is some aricle that explain about this. Please refer it from here you can use it.
Yes. you can plug custom authenticator.. But i guess IWA can help you to achieve this.
I have implemented OAM SSO Authentication for my web application deployed on weblogic. Now i want use weblogic embedded LDAP to provide app level authorization. I dont want to use the weblogic authentication, just the authorization since i already have authentication handled by OAM. Is that possible? Can someone please point me to any examples, tutorials, or ideas to achieve this?
Depending on your OAM version, you need to add a OAMIdentityAsserter Provider in your WLS domain. I say depending on your OAM verison, because you need to tell it which type of cookies to use.
OAM Admin guide will tell you how to do this.
I have set up OpenDS and installed the DSML service in Tomcat.
I can verify that the setup works correctly. However, I cannot authenticate to make changes using the DSML service.
In soapUI, I have prepared a request. I have put the principal and password in the HTTP basic authentication properties of the request.
However, when executing the call, I get the following error message in the response from the service:
The entry o=TestOrgUnit,dc=example,dc=com cannot be added due to insufficient access rights
What is the correct way of specifying the credentials otherwise? Is it something that must be done in the SOAP request message?
This should work as long as the principal is in the form of a DN (of an existing user).
The server should also have access controls setup to allow that users to Add entries.
Insufficient access rights seems to indicate that either the LDAP connection was not authenticated, or the ACI do not allow that user to add to the OpenDS directory.
You might want to check OpenDJ DSML gateway as it offers more capabilities that OpenDS with regards to authentication (including support for LDAPS). The trunk or OpenDJ 2.5.0-Xpress1 have that support.

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:

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.
