No, if you set an option for a port, it only affects that port.

Before I switched to poudriere, I used to set options on each port
individually, which got to be an unmaintainable mess.  Now I set the
options in the make.conf files that poudriere uses.  In this case, you
would put:
OPTIONS_SET=LDAP
in the make.conf file to set the option globally for all ports.  It is
also possible to set an option for only one port like this:
category_portname_SET=SOMEOPTION
Options can also be turned off by using UNSET instead of SET.

With poudriere it is also possible to build different collections of
ports with different options by using different make.conf files for
each.
