/** @struct krb5plugin_kuserok_ftable_desc
*
* @brief Description of the krb5_kuserok(3) plugin facility.
*
* The krb5_kuserok(3) function is pluggable. The plugin is named
* KRB5_PLUGIN_KUSEROK ("krb5_plugin_kuserok"), with a single minor
* version, KRB5_PLUGIN_KUSEROK_VERSION_0 (0).
*
* The plugin for krb5_kuserok(3) consists of a data symbol referencing
* a structure of type krb5plugin_kuserok_ftable, with four fields:
*
* @param init Plugin initialization function (see krb5-plugin(7))
*
* @param minor_version The plugin minor version number (0)
*
* @param fini Plugin finalization function
*
* @param kuserok Plugin kuserok function
*
* The kuserok field is the plugin entry point that performs the
* traditional kuserok operation however the plugin desires. It is
* invoked in no particular order relative to other kuserok plugins, but
* it has a 'rule' argument that indicates which plugin is intended to
* act on the rule. The plugin kuserok function must return
* KRB5_PLUGIN_NO_HANDLE if the rule is not applicable to it.
*
* The plugin kuserok function has the following arguments, in this
* order:
*
* -# plug_ctx, the context value output by the plugin's init function
* -# context, a krb5_context
* -# rule, the kuserok rule being evaluated (from krb5.conf(5))
* -# flags
* -# k5login_dir, configured location of k5login per-user files if any
* -# luser, name of the local user account to which principal is attempting to access.
* -# principal, the krb5_principal trying to access the luser account
* -# result, a krb5_boolean pointer where the plugin will output its result
*
* @ingroup krb5_support
