These interfaces are functional, but the +interfaces are likely to change in incompatible ways from release to +release. In some cases, it may be necessary to copy header files from +the krb5 source tree to use an internal interface. Use these with +care, and expect to need to update your modules for each new release +of MIT krb5. + + +Kerberos database interface (KDB) +--------------------------------- + +A KDB module implements a database back end for KDC principal and +policy information, and can also control many aspects of KDC behavior. +For a full description of the interface, see the header file +``<kdb.h>``. + +The KDB pluggable interface is often referred to as the DAL (Database +Access Layer). + + +Authorization data interface (authdata) +--------------------------------------- + +The authdata interface allows a module to provide (from the KDC) or +consume (in application servers) authorization data of types beyond +those handled by the core MIT krb5 code base. The interface is +defined in the header file ``<krb5/authdata_plugin.h>``, which is not +installed by the build. |
