You're not listening.

Postfix is not 'responding'... it simply relies on the SYSTEM LIBRARY
function to perform user lookups. As Wietse said, this is an OS (system
library) problem.

It doesn't. Again, it is YOUR OS that is responding with 'user unknown'.

Postfix doesn't talk directly to the LDAP server - again, as Wietse
already told you, it relies on the OS SYSTEM LIBRARIES to handle that.

Please don't shoot the messenger (postfix in this case) because you
don't like the message.
