 Configuration for individual maps should be stored in entries directly

- * nis-domain
+ * nis-domain (required, multivalued)
    The NIS domain in which this map appears.  The server will claim to
    support any domain for which it has at least one map configured.
    There is no default value, and a single map will appear in multiple
    domains if this attribute has multiple values.
- * nis-map
+ * nis-map (required, multivalued)
    The name of this map in the domain.  There is no default value, and a
    single map will appear with multiple names if this attribute has
    multiple values.
- * nis-base
+ * nis-base (required, multivalued)
    The entry under which directory server entries which should be
    converted into NIS map entries can be found.  There is no default
    setting.  If this attribute has more than one value, the resulting
    NIS map will include every entry which can be found by searching
    under all of the specified entries.
- * nis-secure
+ * nis-secure (optional)
    Indicates that the contents of this map should only be visible to
    clients whose queries originated from port numbers below 1024.  The
    default setting for all maps is "no".
- * nis-filter
+ * nis-filter (optional)
    The filter which is used to select entries for conversion, given as
    an LDAP search filter.  A default value, which varies based on the
    name of the map, is used if none is specified.
- * nis-key-format
+ * nis-key-format (required if nis-keys-format is not set)
    A format specifier which the plugin will use to convert the contents
    of the directory server entry into a key for the NIS map.  If the
    expression fails to evaluate, or evaluates to more than one value,
    the entry will be ignored.  This can be used to ensure a 1-to-1
    mapping between entries in the directory server and a NIS map.  The
    syntax of format specifiers is described in "format-specifiers.txt".
