Hi, I am trying to return a Cisco vendor specific attribute from a python module by adding it to the reply tuple as: (Attr-26, '0x00000009010f54657374417474726962757465') But I am getting the following error in the logs: Debug: authenticate - Failed: 'reply:Attr-26' '0x00000009010f54657374417474726962757465' Any ideas, how I can add VSA to the reply tuple from the python module?
