--- Comment #3 from Howard Chu hyc@openldap.org --- Since the symbol in question is part of an unsupported feature, only built when the unsupported LDAP_CONNECTIONLESS flag is defined, we will not be adding it to the officially released library map files. If you want to add unsupported features to your builds, then you'll be responsible for tweaking your map files appropriately to make those unsupported features visible in your builds.
Thanks for bringing this to our attention and giving us the opportunity to clarify the Project policy on the matter. This ticket will now be closed.
