News. 2011-11 GSS-API is Generic Security Service API (RFC 2744). It provides a common interface for accessing different security services. One of the most popular security Vertica uses the GSS-API (Generic Security Services Application Programming Interface) to communicate with the Kerberos client. When you create an GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Unknown code krb5 194). Error code 194 refers to "Credentials cache file SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)] Aug 16, 2020 It is a modified form of TSIG authentication that uses the Kerberos v5 authentication system.

Consequently, it helps applications to decouple themselves from the security mechanisms directly. To clarify, security here spans authentication, data integrity, and confidentiality. 2.1. The cyrus-imap package uses Kerberos 5 if it also has the cyrus-sasl-gssapi package installed. The cyrus-sasl-gssapi package contains the Cyrus SASL plugins which support GSS-API authentication. Cyrus IMAP functions properly with Kerberos as long as the cyrus user is able to find the proper key in /etc/krb5.keytab , and the root for the principal is set to imap (created with kadmin ). DESCRIPTION ¶ The Kerberos system authenticates individual users in a network environment.

Rather, it is a framework that provides security services to callers in a generic fashion, supportable with a range of underlying mechanisms and technologies such as Kerberos v5 or public key technologies, as shown in Figure 1–1: Figure 1–1 The GSS-API Layer GSSAPI is an industry-standard protocol for secure authentication defined in RFC 2743. PostgreSQL supports GSSAPI with Kerberos authentication according to RFC 1964. GSSAPI provides automatic authentication (single sign-on) for systems that support it.

This is presently used only for carrying the IAKERB conversation to be checksummed in the GSS authenticator. For each cassandra node, create a new Kerberos service principal (see here for further details) Note that the service name portion of the principal (cassandra, in this example) must be the same for each node in the cluster, and must also match the SASL protocol name specified when configuring the Cassandra Java driver Kerberos authenticator.The hostname portion of the principal (e.g. node1 Use of RPCSEC_GSS and Kerberos V5 Status of this Memo.

Apparently the kvno for the kadmin/admin was out of sync with the /etc/krb5/kadm5.keyfile.

Beginning with version 3, NFS supports generic security services for RPC (RPCSEC_GSS), which enables the use of Kerberos 5. Kerberos provides strong secure authentication for client/server applications.

GSS uses GNU Shishi to implement the Kerberos V5 mechanism. Projects using GSS include: GNU SASL.

In this scenario, your applications may want access to the Kerberos ticket so that they can re-use it to interact with other services secured by Kerberos.

The GSS-API SASL mechanism is described in RFC 2222. It specifies how GSS-API services can be used for SASL authentication and establishment of a security layer.

GSS-TSIG (Generic Security Service Algorithm –Transaction Signature) is used to authenticate DDNS (Dynamic Domain Name System) updates. It is an extension of TSIG authentication that uses the Kerberos v5 The RPCSEC_GSS protocol, defined in RFC 5403, is used to provide strong security for RPC-based protocols such as NFS. Before exchanging RPC requests using RPCSEC_GSS, an RPC client must establish a GSS security context.
