building openldap form ports

[Friedrich Locke]

Hi folks,

i am learning a lot with this mailing lists, thank you for your replies.
I would like to build and install openldap server from the ports 
collection. In the configuratin process i was told that bdb is 
deprecated, then which backend should i build support for ?

In my slapd.conf which backend should i specify ?

Thanks a lot for your time and patience.

Best regards.
