We have OpenAM plugin for Apache Http server.
Here Apache Http server works as reverse-proxy.
OpenAM plugin validates user requests for authentication and authorisation then forwards the requests to service.
This works fine for some days. But suddenly, OpenAM plugin fails to authenticate and authorise and requests directly goes to service.
Only fix is to restart the Apache HTTP server.
But this is not the correct fix. We would like to find the real route cause of this problem and fix. There is no logging reported from http server.
Thanks.
There is no logs reported. Totally clueless. It is happening once in two days or >so.
You should set the Agent level to message and check the debug.log (in agent root --> instances --> debu --> debug.log) and trace the requests in the agent log files that are not working. There may also be relevant information in the system logs in the agent root log folders.
But suddenly, OpenAM plugin fails to authenticate and authorise and requests
directly goes to service.
What HTTP status code is returned during this period? By default, if the Agent cannot communicate to AM for policy advice (unless it has preconfigured fallback not enforced URLs) will be to 403 each request. You'd really need to check your debug and apache access logs to look at these requests hitting the reverse proxy (or whether they hit them at all).

I'm using oauth2-proxy with Keycloak to authenticate to applications.
Oauth2-proxy sits in the front, and when a request comes to port 4180 it redirects to Keycloak, once you authenticate it redirects to the upstream address (where the application lives)
This works well as long as the application is on the same server as oauth2-proxy.
When the application is on a different server, all the same process goes well with no errors, (exact same configuration except for the upstream which now points to another server:port), but instead of redirecting to the upstream app on the other server, it redirects to the same server:4180 and shows me an Nginx welcome page.
Could this be a configuration issue, or is it mandatory that the application is in the same server as oauth2-proxy?
I developed an application that uses Azure AD Authentication for a single tenant.
I would like to host it inside AKS, but it seems not to be possible, as described below:
The problem is that the application must be running as https if it is not in localhost, but my pod is running on http protocol (as usual). Even if my aks cluster service is running as Https, the callback uri seems like to be looking for the protocol on the pod where it's running, so it redirects the request to http://mydomain and not https://mydomain, returning the "Correlation Error" or "app id doesnt exists" (because the mapped uri was https://)
The redirect URI can not be mapped to http on Azure App as described here.
I've made it work using a certificate inside my pod on the application build using Kestrel Certificate. But it seems not to be a good solution.
Does anyone knows a more suitable workaround?
As of now there is no other solution available as we have restrictions in redirect URL as per the document you are following.
We have a couple of back-end web applications to which we want to provide access via the public internet. To that end, we are setting up a reverse proxy (IIS 7.5) from our DMZ. At the same time, we want these web applications to be claims-enabled through ADFS 2.0.
WEB1.MYCORP.COM/WFE1 is the other back-end web application, on our internal network
WEB1.MYCORP.COM/WFE2 is the other back-end web application, on our internal network
ADFS.MYCORP.COM is the ADFS 2.0 server, on our internal network
FSPROXY.MYCORP.COM is the ADFS 2.0 proxy server, on our DMZ
RPROXY1.MYCORP.COM is the reverse proxy for WFE1, on our DMZ
RPROXY2.MYCORP.COM is the reverse proxy for WFE2, on our DMZ
In keeping with the proper configuration of ADFS, our internal DNS resolves ADFS.MYCORP.COM to the actual internal server, while external DNS points ADFS.MYCORP.COM to the ADFS proxy (FSPROXY).
So, here's the scenario:
End user browses to RPROXY.MYCORP.COM
Reverse proxy forwards request to WEB1.MYCORP.COM/WFE1
WFE1 redirects browser to ADFS.MYCORP.COM (actually FSPROXY)
ADFS Proxy prompts for credentials and authenticates against ADFS server
Upon successful authentication, browser redirected back to web app
I have a couple of questions. Do I need to configure something in the rp or the application to allow this. Also the adfs endpoint is the rp url is that an issue?
Do I need to set up something for the reverse proxy as well? (Should I/can I) set up a claims-enabled reverse proxy in IIS? How do I set up the reverse proxy rules to pass back the ADFS request unaltered? Currently, when I try to access the back-end application, it fails with a 401 authentication error. If I remove the proxy and just hit the app server it works fine.
Further,
This fails:
The path is client --> rp -->app -->adfs --> rp -->app --> rp -->client machine
this works:
The path is client -->rp -->app -->adfs -->app -->rp -->client machine
Any suggestions would be greatly appreciated!
Not familiar with how you enabled reverse proxy in IIS (ARR?). Something like this http://blogs.iis.net/carlosag/setting-up-a-reverse-proxy-using-iis-url-rewrite-and-arr
One choice for you is to use ADFS 2012R2 (if possible) because the proxy in that, the Web Application Proxy, handles both ADFS authentication and can handle app publishing for your claims enabled application. There are 2 ways you can publish your app to the internet. Once is pass-through which is kinda what you are trying to do. But it also allows pre-authentication support for a claims aware app. This way, you can have a different policy that decides whether the application can get pass your EDGE network before a packet goes to your internal application.
After doing lots of digging and fiddler traces I found the issue. In testing idp setup the token was different then stage env. The fiddler traces showed that the token was making it back to the app server. The issue was it also looked like the cookie dropped off for no reason. The issue was because the old dev ipd value disagreed with the stage value...naturally. Once I cleared the old token from the database everything worked.
I have setup IBM MobileFirst 7.0 with IBM HTTPServer. HTTPServer only listens for SSL traffic on 443 (no requests over http on port 80 are being processed). The plugin-cfg.xml is directing the /appcenterconsole URLs to the WebSphere Liberty server running the MobileFirst app.
At first, the App Center console loaded and I could login, but any calls to /appcenterconsole/services/* were getting a certificate chain error. I fixed this by adding the http server's certificate to the Liberty keystore. After executing this change, the behavior changed such that on login to App Center, the user immediately receives a 'Your session has expired' message and is sent back to the login page.
Why is my session getting lost? The HTTP server has a JSESIONID for requests to /appcenterconsole/*.
Can the HTTP plugin send the traffic over http to the Liberty server to avoid the SSL chain issue?
This looks like an SSO (Single Sign On) problem. There are two web application, AppCenterConsole and AppCenterServices, and both require authentication, hence they should be set up with SSO. It seems you reach the AppCenterConsole but not the AppCenterService.
Liberty has SSO by default, but if you are using multiple servers, ensure that you have followed the instructions Configuring LTPA on the Liberty profile in the Websphere Liberty Profile documentation.
Alternatively, you can set the JNDI property ibm.appcenter.ui.cors to false for the AppCenterConsole. This will avoid the redirection of requests from the AppCenterConsole to the AppCenterService. If it doesn't already fix the problem, then at least it will produce a better error message with a stack trace that points to the real problem.
I have a web application with servlets and jsps running on tomcat. I have enabled the tomcat to use https for all the users/visitors. I want to know if there is a way I can disable the https for users who are not logged in and are just browsing through the application.
Thank you
If you are searching by a Tomcat setting to do that, the answer is no. If you open a port https/ssl security, you opened it for everyone (the only exception is if you intent to use client authentication using ssl client certificates, that a guess is not the case here).
However, you can check if the user is accessing using https (using HttpSerlvetRequest.isSecure()) and send him back to http with a redirect, or change all page links to starts with 'http', if he is not logged in. That will make sure that any link the user clicks will send him back to http.
