First, update your base OS, you are a couple of patches behind.

Second, read the handbook. Handbook: Chapter 5 Installing Applications: Packages and Ports

net/openldap24-server

Sorry, but I cannot use ports

My machine isn't connected to the internet, is there any other way I could apply the patch?

Thanks.
