+- bsc#1085064 Add script "openldap_update_modules_path.sh" which
+  which removes the configuration item olcModulePath in cn=config
+  which is after upgrade from SLE12 to SLE15 holds inappropriate
+  information. If the cn=config is being used on a system, the
+  conflicting items in slapd.conf are ignored, despite of it, the
+  backend DB configuration section has been also commented out in
+  the default slapd.conf.
+  In case of correct cn=config (the olcModulePath has been already
+  removed), the script stops without touching anything.
