Certificate chain untrusted

Hi, I've got configures freeradius 3.2 with eap tls, and working certificates, users can be authorized to network but I get warnings every time : Certificate chain - 1 cert(s) untrusted (TLS) untrusted certificate with depth [1] subject name /C=PL/ST=MyState/O=MyOrg/CN=Intermediate CA (TLS) untrusted certificate with depth [0] subject name /C=PL/ST=MyState/O=MyOrg/CN=client Is there solution to this or so I have to ignore it, and live with it?
