Hello,

Does anybody know how to remove the "" in the answere arround presto ?
Please find here an example of the access-accept answere sended by my 
FreeRadius server.

---BEGINING---
Sending Access-Accept of id 6 to 212.xx.xx.xx port xxx
         Redback-Subscriber-Profile-Name := "presto"
         Service-Type := Framed-User
         Framed-Protocol := PPP
         Framed-IP-Address := 255.255.255.254
---END---

Thank you very much,

Regards,


Thomas
