Huntgroup-Name

Hi, I use the huntgroup text file for my NAS myshare NAS-IP-Address == 192.168.102.43 and now I would like to do a check in sites-enabled/default post-auth { (0) if ("%{Huntgroup-Name}" == "myshare") { (0) ERROR: Failed retrieving values required to evaluate condition (0) else { How could I access/or is there a variable with the name of the huntgroup? There are only examples using sql :(. Thanks + Regards Carsten
