module fails parsing output, expecting operator

[Richard Green]

Hi Matthew

You are correct with regards to the use of the script /usr/local/bin/multiotp.php being used in both the authenticate and authorize sections, and that script returning a value which, when parsed by FreeRADIUS 3, resulted in an an error.

To work around this issue, I was able to write wrapper scripts to parse the output of /usr/local/bin/multiotp.php, so they only return one output pair.

Thank you for your help :)

It's returning

  Filter-Id += "Erica-Users",NT_KEY: EBEEE229885004ACEA55894DFDC1272D

that's not a valid response, at least not from the ',' onwards.

It wasn't a valid response in v2, either. I suspect the code may have
been a bit more lax in what it was willing to accept.

The external script needs to be fixed to return valid output pairs.

However, it looks like it's also being used to run ntlm_auth. Therefore
I'd hazard a guess that it needs to be passed an argument to return
either the output pairs (Filter-Id += "Erica-Users") or the NT key
(NT_KEY: EBEEE22...) depending on whether it's called from 'exec' or
from 'mschap', as they expect to see different formats.
