I'm working on accessing Microsoft Endpoint Configuration Manager (SCCM)and it uses Kerberos authentication. I need help in understanding how can I generate the Authorization header (negotiate) with the given username and password which have access to the SCCM server.

i am using the Api Manager service and i have configured my API to use Oauth authentication but to an authentication server in my company, that is, i am not using Azure Active Directory but i get the following error: An HTTP connection to authorization server could not be established or it has been unexpectedly closed. And i do not know what it is lack to configure. I tried giving access to the IP of my API in the authentication server but the problem persists.
I was able to solve my problem. It was due first to my authentication server requiring a certificate so I had to add the certificate "Certificate CA". Then within the configuration of Oauth I had to add as parameters of the bopy the Client Id and secret ID and leave as an authentication method in the body
We have a scenario where we have to authenticate the user with LDAP server
Flow 1:
client --> application server --> LDAP server
In above flow the client enters LDAP credentials which comes to application server and then using python-ldap we can authenticate the user, straight forward. Since the user LDAP credentials comes to application server an organisation may not be willing for such flow for obvious reasons.
Flow 2:
client --> oauth2 --> LDAP server
Oauth scenario suites best here, since authentication of the user is responsibility of the oauth and application server do not need to know the user credentials.
Have anyone encountered such case, if yes, how you tackled it?
Is there are any Oauth client for LDAP free and paid ?
If you don't want user credentials to reach the Application server then what you need is a perimeter authentication. You need to have an external authentication provider , say Oracle Access Manager, that will perform the authentication and set a certain token in the request. The application server can assert this token and let user access resources. This model enables SSO as well.
The resources that require authorized access are configured as protected URLs in OAM.
When a user tries to access a protected resource he is challenged for credentials.
OAM authenticates the user against an LDAP directory(that is configured in OAM).
A token corresponding to the authenticated user is set in the request. Also an SSO cookie is set.
Application server (Weblogic) can assert (verify) this token and let the user access the resource.
Note: Oracle Access Manager supports oAuth as well.
Ory Hydra https://ory.sh/hydra might be what the original poster was asking for. This question is several years old now but in the interest of helping anyone else who sees this...check out Ory Hydra. It provides the OAuth2/OpenID parts and can be linked to an LDAP server behind the scenes.
canaille is a free and light OAuth2/OpenID service over a LDAP backend, written in python. (canaille developper here)

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'm currently have a selfhosted WCF REST service. Using WebHttpBinding and Windows authentication, is it possible at all to get the password or do I have to use Basic authentication?
You can't get the user password using Windows auth - since the authentication is done via a third party (usually the active directory), no passwords are exchanged between the client and the service, only a token which is issued by the AD.
Being able to get the password using Windows auth would also be a huge security risk - in intranets clients (such as browsers) usually don't prompt the user for credentials when authenticating themselves to a server which requires that kind of authentication. You wouldn't want your password to be handed over to a service which you happen to visit that uses that kind of authentication.
I have developed one REST WCF and would like to client will use it with basic Authentication, I have hosted this service in IIS 7.0 and disabled all authentication except Basic Authentication.
Now problem is that when call this service from any other application (in my case i am calling this from ruby command prompt) with Header "Basic bXlhZGRvbjpDcFplcUc5MzlHdDZQMEtD" although i was not able to authenticate this service.
Make it more simple , when i will access this service (.svc) from browser due to basic Authentication
it will prompt to enter username & password , so which residential i need to pass here and to which credential i need to compare (weather i need to set in web.config or IIS)??
Thanks in Advance
Arun.
For basic authentication, IIS would always try to validate the userName & Password as a windows users (either local or domain user).
Dominick has created a Basic Http Authentication module which let's you use other credential stores with Basic Authentication.
