I can't get SQL xlat to work in the Clients file. I'm trying to do a DB query for the Shared Secret.

And where did you find that it should work?

I'm getting invalid Message-Authenticator (Shared secret is incorrect) errors.

You should fix client secret to match the server not other way round.

The select statement works fine when ran on my DB server.

Have any suggestions?

You can load clients from nas table. See read_clients setting near the end of sql.conf file. Ivan Kalik Kalik Informatika ISP
