Below is my scenario:
Client is connecting to intermediate service and intermediate service is connecting to the target service. I want to use the client credentials from the intermediate service to connect to the target service.
I used the below code in the intermediate service to acquire the credentials of the client.
GSSCredential clientCredential =((ExtendedGSSCredential)intermediateServiceCreds).impersonate(clientGSSName);
Establishing the context is failing with
NOT_ALLOWED_TO_DELEGATE
Do I need to set any flags while creating the principle of the client, intermediate service and target service? I don't want to make code changes in the client to set the credential delegation to true.
Looks like your intermediate service principal is missing "ok_to_auth_as_delegate" attribute. https://web.mit.edu/kerberos/krb5-devel/doc/admin/admin_commands/kadmin_local.html#add-principal

I have a Data Factory that is being using private endpoint and would like to configure an integration runtime to have conection between my ADF and an SQL Server that is in another organization but without using vpn connection.
What I've been trying. I create a new record (CNAME) on DNS to direct mytest.domain.com to my FrontDoor and there I've configured a frontend (mytest.domain.com) > backend (adf service endpoint) > routing rule then in the IR side I grab the key authentication from ADF and change the adf service endpoint for my CNMAE was created mytest.domain.com mantaing the others information. Therefore when I go to IR to register it I got error saying
Is possible have my ADF as private endpoint and expose it using FrontDoor and limited it only for the IP of my client?
I'm expecting to allow only the client IP to connect by IR using FrontDoor instead a VPN.
We have a cluster that runs a number of dotnet apps, one of which runs the identity server. All the other apps need to authenticate with the identity server. If the identity server was external this wouldn't be an issue as it would have an HTTPS endpoint, but internally they are all running HTTP.
With istio adding MTLS security to all the comms, do all the apps just get set with RequireHttpsMetadata = false?
Is this the correct way to setup the network with internal requests being sent as http://auth-server.default.svc.cluster.local/...?
or should they be sent as https://auth-server.default.svc.cluster.local/..., if so how?
I would like to know whether OSB plays a crucial role in terms of security apart from just behaving as a middle-ware.
Inbound Security:
Inbound security ensures that Oracle Service Bus proxy services handle only the requests that come from authorized clients. (By default, any anonymous or authenticated user can connect to a proxy service.) It can also ensure that no unauthorized user has viewed or modified the data as it was sent from the client.
You set up inbound security when you create proxy services and you can modify it as your needs change. For outward-facing proxy services (which receive requests from service consumers), consider setting up strict security requirements such as two-way SSL over HTTPS. For proxy services that are guaranteed to receive requests only from other Oracle Service Bus proxy services, you can use less secure protocols.
For each proxy service, you can configure the following inbound security checks:
Transport-level security applies security checks as part of establishing a connection between a client and a proxy service. The security requirements that you can impose through transport-level security depend on the protocol that you configure the proxy service to use.
For example, for proxy services that communicate over the HTTP protocol, you can require that all clients authenticate against a database of users that you create in the Security Configuration module of the Oracle Service Bus Administration Console. You then create an access control policy that specifies conditions under which authenticated users are authorized to access the proxy service.
Custom Authentication for message-level security. Oracle Service Bus supports client-specified custom authentication credentials for inbound transport- and message-level requests. The custom authentication credentials can be in the form of a custom token, or a username and password.
Message-level security (for proxy services that are Web Services) is part of the WS-Security specification. It applies security checks before processing a SOAP message or specific parts of a SOAP message.
Outbound Security
Outbound security secures communication between a proxy service and a business service. Most of the tasks that you complete for outbound security are for configuring proxy services to comply with the transport-level or message-level security requirements that business services specify.
For example, if a business service requires user name and password tokens, you create a service account, which either directly contains the user name and password, passes along the user name and password that was contained in the inbound request, or provides a user name and password that depend on the user name that was contained in the inbound request. For more information, see Section 2.1.15, "Creating Service Account Resources."
If a business service requires the use of PKI technology for digital signatures, or SSL authentication, you create a service key provider, which provides private keys paired with certificates. For more information, see "Service Key Providers" in the Oracle Fusion Middleware Administrator's Guide for Oracle Service Bus.

I have a project that have embedded jetty with SPNEGO enabled. I would like to be able to run this project locally for development purposes (WITH SPNEGO enabled!)
My question is, is the SPN and keytab associated with a particular server at all or can I use the same set on multiple instances of my service?
Kerberos requires that both the client and server somehow figure the service principal to use without any prior contact. If you have control of both the client and server, you can use any principal you want provided you configure both sides to
use the same principal.
In the SPNEGO case, the client does the "standard" thing and builds a principal based on the hostname of the server. (i.e. I want to talk to www.foo.com, I'll try
requesting an HTTP/www.foo.com service ticket and see if the server accepts it. )
I don't know of any way to get the SPNEGO code in the browser to use a fixed service principal. So in this case you'll need a separate keytab for each server.
I need to deploy a Azure Worker Role with input endpoint on port 21 so that it can accepts incoming FTP connections.so that i should be able to connect to worker role through FTP Client like Filezilla and access the azure blob storage.
For secured communication between client and SErver(Azure worker role) i need to implement AUTH TLS/SSL command.
can we able to support FTP over SSL/TLS - aka FTPS (FTP secure) on Azure Worker role via socket programming(tcplistener and tcpclient).
Regards,
Vivek.
IF you make sure that FTP server is running in the Windows Azure Worker Role, you sure can configure a TCP/IP endpoint in worker role set to use port 21 and then configure a SSL certificate set over this TCP/IP endpoint. Once endpoints are properly configured in the worker role along with SSL certificate bindings, and the application listening on those port is able respond to incoming connections, you can make secure FTP connection.
The bottom line is that you would need to configure it correctly they way you want and the infrastructure will not prohibit your doing so, just you would need to make it happen correctly.
