GSSAPI PROGRAMMING GUIDE PDF
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.

University of Bamberg Press. A serialized credential should not be trusted if it originates from a source with lower privileges than the importer, as it may contain porgramming to external credential cache, keytab, or replay cache resources not accessible to the originator.
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. A krb5 GSSAPI credential may contain references to a credential cache, a client keytab, an acceptor keytab, and a replay cache.
This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.
The memory pointed to by the buffers is not required to be contiguous or in any particular order. The value should be a string of the form service or service hostname. DATA buffers must be provided in the iov list so that padding length can be computed correctly, but the output buffers need not be initialized.
Serializing a credential does not destroy it. 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].
Is there any way of providing user’s public key that way? As above, but the value is a decimal string representation of the uid. After the exchange of some number of tokens, the GSSAPI implementations at both ends inform their local application that a security context has been established.
Please help to improve this article by introducing more precise citations. If the input name contains both a service and a hostnameclients will be allowed to authenticate to any host-based principal for the named service and hostname, regardless of realm. In this case, the contents of the credential cache are serialized, so that the resulting token may be imported even if the original memory credential cache no longer exists.
If the security implementation ever needs replacing, the application need not be rewritten. On Unix-like systems, the username of the uid is looked up in the system user database and the resulting username is parsed as a principal name.

Views Read Edit View history. 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.

Probably you are looking for kerberos with pkinit support. The value is ignored. The application must pad the DATA buffer to a multiple of 16 bytes as no padding or trailer buffer is used. Because of this, a serialized krb5 credential can only be imported by a process with similar privileges to the exporter.
The value is treated as an unparsed principal name string, as above. The following name types are supported by the krb5 mechanism: Integration Strategies, Patterns, and Best Practices. After this your machine will receive a TGT, and this transaction happens during domain login or while doing a kinit. Contents previous next index Search feedback.
