+.SH NOTES
+Databases that are glued together should usually be configured with
+the same indexes, even for attributes that only exist in some of
+these databases.
+A search for an attribute which is only indexed in some of the glued
+databases must otherwise examine each entry in the search scope in the
+other databases, looking for the attribute.
+
+If the extra indexes assist searches one would prefer not to
+support, these can be disabled with access controls in some of the
+databases.
+E.g.:
+.RS
+access to attrs=cn by * =rcxd

+See
+.BR slapd.access (5).
