You can use certutil on the master to make a cert for the slave,
using
the above command on the master. Then, use pk12util to export the slave
cert/key, then take that pk12 file to the slave and use pk12util to import
it (and use certutil to import the CA cert).
Thanks for this, it worked. I had to disable: check hostname against name
in cerfificate for outbound SSL connections, but its actually working now.
