|
|
* Declarations for password quality plugin module implementors.
|
|
*
|
|
* The password quality pluggable interface currently has only one supported
|
|
* major version, which is 1. Major version 1 has a current minor version
|
|
* number of 1.
|
|
*
|
|
* Password quality plugin modules should define a function named
|
|
* pwqual_<modulename>_initvt, matching the signature:
|
|
*
|
|
* krb5_error_code
|
|
* pwqual_modname_initvt(krb5_context context, int maj_ver, int min_ver,
|
|
* krb5_plugin_vtable vtable);
|
|
*
|
|
* The initvt function should:
|
|
*
|
|
* - Check that the supplied maj_ver number is supported by the module, or
|
|
* return KRB5_PLUGIN_VER_NOTSUPP if it is not.
|
|
*
|
|
* - Cast the vtable pointer as appropriate for maj_ver:
|
|
* maj_ver == 1: Cast to krb5_pwqual_vtable
|
|
*
|
|
* - Initialize the methods of the vtable, stopping as appropriate for the
|
|
* supplied min_ver. Optional methods may be left uninitialized.
|
|
*
|
|
* Memory for the vtable is allocated by the caller, not by the module.
