What is javax security Auth useSubjectCredsOnly?
The useSubjectCredsOnly System Property For this tutorial, we set the system property javax. security. auth. useSubjectCredsOnly to false , which allows us to relax the usual restriction of requiring a GSS mechanism to obtain necessary credentials from an existing Subject, set up by JAAS.
What is a Kerberos context?
The InitializeSecurityContext (Kerberos) function initiates the client side, outbound security context from a credential handle. The function is used to build a security context between the client application and a remote peer.
What is Java GSS?
Java Generic Security Services (Java GSS-API) is used for securely exchanging messages between communicating applications.
Is Gssapi secure?
The GSSAPI, by itself, does not provide any security. The client and server sides of the application are written to convey the tokens given to them by their respective GSSAPI implementations. GSSAPI tokens can usually travel over an insecure network as the mechanisms provide inherent message security.
What is Gssapi Kerberos?
The GSSAPI (Generic Security Services API) allows applications to communicate securely using Kerberos 5 or other security mechanisms. We recommend using the GSSAPI (or a higher-level framework which encompasses GSSAPI, such as SASL) for secure network communication over using the libkrb5 API directly.
How do you use Kerberos authentication in Java?
Procedure
- Create a Kerberos configuration file (krb5.
- Place either the krb5.
- In the sas.
- Also in the sas.
- If the authenticationTarget is KRB5, the Java client application must have the wsjaas_client.
- If the authenticationTarget is KRB5 and loginSource is the Kerberos credential cache, do the following:
What is GSSCredential?
A GSSCredential contains all the cryptographic information necessary to create a context on behalf of a principal and can contain credential information for multiple mechanisms. An acceptor that also behaves as an initiator creates initiate and accept credentials.
