--- Comment #7 from Howard Chu hyc@openldap.org --- I don't see any provision for deleting individual values from the configs in bconfig.c. That needs to be addressed.
I think it will be better overall to just make the internal structure store a charray, but that still doesn't address how to undo a setting when it's deleted from the config string.
