All available bug fixes should now be in OPENLDAP_REL_ENG_2_2. Please test. I intend to release this as .16 later this week. If a fix (in HEAD) is missing (in OPENLDAP_REL_ENG_2_2), holler. (Note: I know of a number of fixes that are "in the works". Depending on when they are ready, they'll either go into .16 or some subsequent patch release.)
