I have set WANT_OPENLDAP_SASL in /etc/make.conf
When I build net/samba410 or net/nss-pam-ldapd without synth and without having openldap-sasl-client installed both ports will use openldap-sasl-client.
When doing this using synth, they will build against openldap-client.
This in turn will result in openldap-sasl-server getting uninstalled...
Is this a bug or a configuration error on my side?
It looks like synth just ignores /etc/make.conf.
After copying /etc/make.conf to /usr/local/etc/synth/LiveSystem-make.conf net/samba410 net/nss-pam-ldapd are built against openldap-sasl-client.
Sorry for the noise.
