KADM5 hook interface (kadm5_hook)ΒΆ

The kadm5_hook interface allows modules to perform actions when changes are made to the Kerberos database through kadmin. For a detailed description of the kadm5_hook interface, see the header file <krb5/kadm5_hook_plugin.h>.

The kadm5_hook interface has four primary methods: chpass, create, modify, and remove. Each of these methods is called twice when the corresponding administrative action takes place, once before the action is committed and once afterwards. A module can prevent the action from taking place by returning an error code during the pre-commit stage.

A module can create and destroy per-process state objects by implementing the init and fini methods. State objects have the type kadm5_hook_modinfo, which is an abstract pointer type. A module should typically cast this to an internal type for the state object.

Because the kadm5_hook interface is tied closely to the kadmin interface (which is explicitly unstable), it may not remain as stable across versions as other public pluggable interfaces.
