That's all it means.

MacOS has nothing to do with the classic UNIX approach of free and open

The culture is not UNIX culture, it's BSD and GNU. The entire "classic UNIX approach of free and open" was anti-UNIX backlash! A little history is needed to understand why.

Until "recently", UNIX was a monolithic copyright and licensed software hoarded by AT&T.
Richard Stallman disliked the closed binary approach and began GNU to create a portable, compatible, open UNIX alternative.
BSD, in modern parlance, was an open, pre-AT&T "fork" of UNIX, in pure sourcecode form. "Binary source distribution" in short.
Linux was a madcap project out of nowhere which got so popular that GNU adopted it over their HURD kernel.

The modern meaning of UNIX has changed. It's now a paper standard and series of tests of describing the languages, API's, programs, and shells that must be available for an operating system to call itself UNIX. Certification is not free. The standards need upkeep paid for somehow.

So, open and closed systems can both be UNIX, the same way different brands of appliances use the same wall sockets. And the standard means that one UNIX system can run the same software as a completely different UNIX system, given source code and a little work.

net::ldapi

Net::LDAPI(3)						User Contributed Perl Documentation					     Net::LDAPI(3)

NAME

       Net::LDAPI - use LDAP over a UNIX domain socket

SYNOPSIS

	use Net::LDAPI;

	$ldapi = Net::LDAPI->new('/var/run/ldapi');

	# alternate way
	use Net::LDAP;

	$ldapi = Net::LDAP->new('ldapi://');

DESCRIPTION

       Communicate using the LDAP protocol to a directory server using a UNIX domain socket. This mechanism is non-standard, UNIX-specific and not
       widely supported.

       All the normal "Net::LDAP" methods can be used with a "Net::LDAPI" object; see Net::LDAP for details.

CONSTRUCTOR

       new ( [SOCKPATH] )
	   Create a new connection. SOCKPATH can optionally be specified, to specify the location of the UNIX domain socket to connect to.

	   If SOCKPATH is not given, the environment variable "LDAPI_SOCK" is evaluated, and if that does not exist, the value "/var/run/ldapi" is
	   used.

	   See "new" in Net::LDAP for further details.

SEE ALSO

       Net::LDAP, IO::Socket::UNIX
