Hi I am newbie in freeradius. Thank you for support. :) I have enabled sqlcounter in mods-enabled directory. When I debug freeradius -X Its giving this error including configuration file /etc/freeradius/3.0/mods-enabled/sqlcounter /etc/freeradius/3.0/mods-enabled/sqlcounter[43]: Reference "${modules.sql.dialect}" not found /etc/freeradius/3.0/mods-enabled/sqlcounter[52]: Reference "${modconfdir}/sql/counter/${dialect}/${.:instance}.conf" points to a variable which has not been expanded. Errors reading or parsing /etc/freeradius/3.0/radiusd.conf I have already tried method from this post. Found on mail list. If I changed in radiusd.conf then its saying duplicate sql module. https://github.com/FreeRADIUS/freeradius-server/commit/bb842ece01025e40906fe... Tried few method from mail list but none of them worked. What I am trying to do is change Mikrotik-Rate-Limit based on time by CoA. Thank you
