I have a site that has SAML enabled security on it's web services. How can I use urllib2 to access this site? Are there any examples showing what I have to do in order to get this to work?
When I access a SAML secure site, should the service url automatically re-direct me to the SAML login site?
Thank you
Answering your second question first: yes, when there is an authentication attempt against a SAML secured resource by an unauthenticated user, the site will redirect to the identity provider.
I'm not particularly familiar with SAML secured web services. The magic words to ask the provider of the resource is what SAML Binding is used. The OASIS spec is at https://www.oasis-open.org/committees/download.php/35389/sstc-saml-profiles-errata-2.0-wd-06-diff.pdf See the sequence diagram on page 25 of 69 : the Enhanced Client or Proxy (ECP) Profile would work well for a webservice.

I am developing a web application using EC2 on AWS.
In this application my client is requesting to use his SSO (Single Sign On) so I can verify the user against his Active Directory. My problem is that I can't get to know where to begin with, these are some of my questions:
1) Is this SSO takes place on my code or on my server?
2) Do I have to make different configuration for differents deployment environments (for example aws, azure, digitalocean, etc)?
3) Where do I define, send and parse SAML 2.0 format?
4) Do I have the send a POST request to the server where the SSO is installed? Or how is it managed?
So far I have found this tutorial, but I am still do not know what to do first, so any step by step information will help a lot.
First you need the client (Identity Provider IdP) SAML2 metadata. This will have their SSO endpoint URL and their X509 signing certificate.
Then you send them your SAML2 metadata with your Attribute Consumer Service (ACS) URL and X509 signing certificate.
Sample metadata here. Or you can build it here.
The certificates are normally long lived self signed certificates. They can be self signed as each side has a copy of the other's certificate which they will use to verify the signed request and response.
You construct a SAMLRequest and POST it to their SSO URL. There's an example request here.
They display their login page to the user and the user authenticates at their end.
They gather attributes for the user from their Active Directory and turn them into SAML attributes and put them in a SAMLResponse.
They POST the SAMLResponse to your ACS URL. There's an example response here.
You verify the signature on their SAMLResponse using their X509 certificate from their SAML2 metadata.
You extract the SAML Attributes from their verified SAMLResponse and take appropriate action in your application, e.g. create the user an account, perhaps their email address is one of their attributes.
The above is called the SAML2 Web Browser SSO Profile, explained here.
Depending on your stack, you can use something like:
Shibboleth (middleware, install on your server, it interrupts requests to specific paths requiring Authn against the Identity Provider [ADFS], and returns the user after successful auth setting some attributes telling you info about the user such as username, etc.). Works best if you can compartmentalize secured content into a particular path on the site like /secure.
SimpleSAMLphp (protect PHP resources directly)
Commercial SAML (ComponentSpace, etc. - works well if .Net app)
Basically, find something for your stack. DO NOT TRY TO ROLL YOUR OWN SAML IMPLEMENTATION!
Is there a way to authenticate the Microsoft or google OAuth token in active directory without using an authentication server?
Here is the scenario:
A client app gets an Microsoft access_token from some external service.
Client app will make a call to some secured web API and pass that access_token along with the request header
If the access_token passed by client is valid then API will provide response to the client.
Is there a way to validate that access_token on API side?
My normal understanding about OAuth 2.0 is there needs to be an authentication server to which both the client and API would talk to as shown in the figure below:
But if the token is provided by some external service, Can we use it to validate our web API. Are there any ways to implement such authentication?
You can learn more about AAD Signing Keys and handling Key Rollover using this page: Signing key rollover in Azure Active Directory
Validation of the token, once you have the signing key, can be done using existing libraries like OWIN. You can also try following instructions like this (although it seems the document isn't 100% complete yet): Manually validating a JWT access token in a web API
This library is also available, but I think OWIN is supposed to have replaced it in general.
Also check out this blog post, which has a pretty great deep dive into token validation.
I am new to this wso2 evaluating wso2,
I am using Identity Server I have web application , want to apply web SSO feature using WSo2, I had check there are soap web service present in wso2 for UserAdmin,
https://server-info:9443/services/UserAdmin.UserAdminHttpsSoap12Endpoint/ using soap client for test , for dev have to write java client for request
but did not find any web services related WEB SSO for example I require authentication web service which will accept Username/password return some token information and using that token I can store in session for single sign out
Is there any web service/ API in wso2 provide authentication? or what is best approach for implement SSO using wso2 for web applications.
Thanks
If you are looking for SSO with WSO2IS, WSO2IS supports several standard ways to achieve it. They are,
SAML2 SSO
OpenId Connect
OpenId
Passive STS (for windows based applications)
From above, most popular way is to use SAML2 SSO or Openid connect. Your web application also must support to talk with WSO2IS using above standards. Say, if you need to achieve SSO using SAML2 SSO. You application needs to send the SAML2 Request and process the SAML2 Response in standard way as mentioned in SAML2 SSO spec. You can find a sample web application that has been implemented to work with WSO2IS from here. This blog contains all configuration details that you need to do in WSO2IS side as well. You can even use the sample web application with other SAML2 IDP as sample web application is talking in standard way. Also. if you are looking for Openid connect, you can find another sample web application from here with config details. I hope this would be a good starting points for you.
I am trying to create an authentication in ADF mobile where the login URL is the peoplesoft login page. When i give in the username and password in the emulator, it throws an error.\
Terminating
Authentication URL responded with an illegal response code.
It is not basic authentication end point.
Please contact administrator
I have followed the following tutorial
https://blogs.oracle.com/shay/entry/accessing_secure_web_services_from
Here instead of creating a remote secured login server, I want to use peoplesoft to authenticate.Any Ideas?
I have also seen somewhere that you can authenticate each web service you call by adding the username and password in the SOAP header. Any tutorials for ADF would be much appreciated and #Shay Shmeltzer any ideas would be helpful
Thanks
Oracle MAF only supports security authentication against HTTP Basic Authentication pages, so I don't think you can use peoplesoft login page to authenticate neither your application nor you web services.
Otherwise you can create a secure ADF page the validates login through peoplesoft login credentials(username-password) then deploy that page to a server and secure your MAF application using that page.
Some useful links

And about your second question yes you can customize the envelop header being send from MAF application to a soap webservice (add username and password or any other attributes) by extending the SOAPProvider class and add it to the datacontrol.dcx file as the provider for the webservice.
The only example I can find online

I'm considering securing a whole Java EE software platform with OpenAM (prev. Sun OpenSSO). Applications - running on WebLogic AS - would be secured by a JEE Policy Agent and web services with WS-Security SAML Token Profile.
As of my understanding, the SSOTokenManager enables application code to retrieve OpenAM's SSO token. But in order to invoke the SAML protected Web Services, I need to obtain a SAML Assertion from OpenAM. Can anybody tell me how to do so ?
Also, in the Web Service code, I may need to get back a SSO Token from a SAML assertion. Is that possible ?
You should be able to achieve both conversions using OpenSSO's Security Token Service. There is a tutorial for configuring it.
The SSOToken is an internal OpenAM representation of a users session, whilst a SAML token is an asserted identity with associated information. As such, these are not directly translatable in the way you describe.
In order to obtain a SAML token for use in your web service call, you should look at the STS functionality in OpenAM. The is a standardised service that will authenticate users and then make an assertion about the identity and authentication of the user, represented by a SAML token. This token is then returned to the calling entity (the web service client) who can include this token as per the relevant WS-* standards.
You may also want to look at the OpenAM wss provider or the Metro/WSIT library to assist implementation on the client side.
