GSSAPI SASL Mechanism Handler

The GSSAPI SASL mechanism performs all processing related to SASL GSSAPI authentication using Kerberos V5.

The GSSAPI SASL mechanism provides the ability for clients to authenticate themselves to the server using existing authentication in a Kerberos environment. This mechanism provides the ability to achieve single sign-on for Kerberos-based clients.

Parent

The GSSAPI SASL Mechanism Handler object inherits from SASL Mechanism Handler.
