Typo in freeradius.inc
There's a small typo in /usr/local/pkg/freeradius.inc on line 2460: conf_mount_r0() should be replaced by conf_mount_ro(). I did not dig deep enough into the code to see what the possible consequences could be–-my installation is working as far as I can tell. At least the error message is gone when starting the radius server.
This occured in package freeradius2 2.1.12 pkg v1.6.5 using pfSense 2.0.1.
Thanks! Fixed that.
If we create certs from the GUI we need to have write ( conf_mount_rw(); ) access to HDD (nanobsd/embedded).
After the files were written on the disk we change back to read-only ( conf_mount_ro(); )
So there shouldn't be a problem with that if using pfsense cert manager. If using freeradius-cert-manager there shouldn't be any big problem, too ;-)
But thank you very much for your help!
