I checked in SUSE and ENOTSUP is available. But, I defined an extra
error in the lib/krb5/error_tables/krb5_err.et file with the intention
that corresponding plugins can add extra information to this error code
and can return more elaborate information.

error_code KRB5_PLUGIN_OP_NOTSUPP,      "Plugin does not support the
operation"
