The Generic Security Service Application Program Interface (GSSAPI, also GSS- API) is an . Sun Microsystems (). “GSS-API Programming Guide”. The GSSAPI (Generic Security Services API) allows applications to communicate securely using Kerberos 5 or other security mechanisms. We recommend. The Secure Shell protocol supports Kerberos authentication via GSSAPI (Generic Security Services Application Programming Interface). Advantages of using.

Note In MIT krb5 versions prior to 1.

GSSAPI tokens can usually travel over an insecure network as the mechanisms provide inherent message security. Are you going to do programming this is not clear form your question?

Do you know if this is a krb library-specific thing, or can putty somehow use this too? Note If a hostname is specified, it will be canonicalized using forward name resolution, and possibly also using reverse name resolution depending on the value of the rdns variable in [libdefaults].

Probably you are looking for kerberos with pkinit support. The following name types are supported by the krb5 mechanism: This page was last edited on 25 Januaryat The memory pointed to by the buffers is not required to be contiguous or in any particular order. Articles lacking in-text citations from October All articles lacking in-text citations Pages using RFC magic links. Please help to improve this article by introducing more precise citations. These name types may work with mechanisms other than krb5, but will have different interpretations in those mechanisms.


After this your machine will receive a TGT, and this transaction happens during domain login or gssspi doing a kinit. Retrieved from ” https: The only guides I’ve found so far are very low-level protocol descriptions or server configuration guides for admins Once a security context is established, sensitive application messages can be wrapped encrypted by the GSSAPI for secure communication between client and server.

Because of this, a serialized krb5 credential can only be imported by a process with similar privileges to the exporter. Post as a guest Name.

As with other GSSAPI serialization functions, these extensions are only intended to work with a matching implementation on the other side; they do not serialize credentials in a standardized format. Sign prgramming or log in Sign up using Google.

The following name types are supported by the krb5 mechanism:.

Kerberos (GSSAPI) Authentication

buide If the security implementation ever needs replacing, the application need not be rewritten. A serialized credential should not be trusted if it originates from a source with lower privileges than the importer, as it may contain references to external credential cache, keytab, or replay cache resources not accessible to the originator.

The application must pad the DATA buffer to a multiple of 16 bytes as no padding or trailer buffer is used.

Is there any way of providing user’s public key that way? I’m looking at a way of authenticating users connecting to gsdapi SSH daemon.

This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations. The calling application must take care to protect the serialized credential when communicating it over an insecure channel or to an untrusted party.

October Learn how and when to remove this template message. Yes, I believe I need to implement my own server-side component to do the authentication, so it’s a programming question. As above, but the value is a decimal string representation of the uid.

The definitive feature of GSSAPI applications is the exchange of opaque messages tokens which hide the implementation detail from the higher-level application. Putty uses this TGT and ghide a service ticket and proceed, so a simple kerberos enabled putty is sufficient. In this case, the contents of the credential cache are serialized, so that the resulting token may be imported even porgramming the original memory credential cache no longer exists.

The anonymous principal is used, allowing a client to authenticate to a server without asserting a particular identity which may or may not be allowed by a particular server or Kerberos realm. Sign up using Facebook. Contents previous next index Search feedback.
