multiple DNs in check_cert_issuer?

Hi list, we have a freeradius server with enabled tls and an own CA. We prove the validity of the cert issuer like it is aoutlined in the example below. check_cert_issuer = "/C=DE/ST=somewhere/L=someplace/O=AnyCompany" No we want to change our CA and want to use two CAs for a couple of weeks. Is it possible to configure that? Thanks Stephan
