| * 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. | |

| * - KADM5_PASS_Q_GENERIC: unspecified quality failure | |
