Hi I am totally new to freeradius and with the help of the excellent wiki ( https://wiki.freeradius.org/guide/eduroam) have a working test server with only one apparent simple niggling issue, operator name matching is case sensitive when using the expression below to match multiple domains. I understand that cannot use "/i" in the this instance but am really struggling to find another way making this case insensitive. I should really appreciate it if someone could give me a hint, point me in another direction or even better give an example. many thanks Pete if (&Stripped-User-Domain != "${operator_name1}") && (&Stripped-User-Domain != ${operator_name2}")&& (&Stripped-User-Domain != "${operator_name3}") && (&Stripped-User-Domain != "${operator_name4}") { update { control:Load-Balance-Key := &Calling-Station-ID control:Proxy-To-Realm := 'eduroam' # Operator name (RFC 5580) identifies the network the # request originated from. It's not absolutely necessary # but it helps with debugging. request:Operator-Name := "1${operator_name1}" } return } -- <https://twitter.com/warwickshirecol> <https://www.facebook.com/WarwickshireCollege>   <https://www.linkedin.com/edu/warwickshire-college-group-355076>  <https://www.instagram.com/warwickshirecol/> College Email Disclaimer This message and any files transmitted with it is intended for the addressee only and may contain information that is confidential or privileged.
