Hi - I've been reading through WiKi pages but still not clear. I need to evaluate two attributes and I'm doing this with the =~ operator. But the second attribute is not evaluated but instead returned as reg expr (exactly as stated below) DEFAULT *User-Name =~ "^([aA-zZ]+)-([aA-zZ]+)$", Auth-Type := Local, User-Password == "csetestp"* Alc-Subsc-ID-Str := "%{NAS-Port-Id}", Alc-Subsc-Prof-Str := "%{1}", Alc-SLA-Prof-Str := "%{2}", Alc-MSAP-Serv-Id := "100", Alc-MSAP-Policy := "msaps", *NAS-Port-Id =~ "^([^:]+):", * Alc-MSAP-Interface := "port-%{1}" Why is NAS-Port-ID returned, according to operators is should not be. I'm trying to evaluate NAS-Port attr and then based on the results assign a value to the last attribute: Alc-MSAP-Interface. If I put a DEFAULT keyword with credentials (Auth-Type, User-Pswd), infront of NAS-Port-Id, then, NAS-Port-Id and Alc-MSAP-Interfaces are not returned at all. What is the significance of this 'DEFAULT' keyword in the 'users' file? Thanks, Marlon
