[RADIATOR] Password Length Limits

What do the log files say? Is an accept/reject packet being sent, or is the request just terminating part way through (or even not reaching the radiusd)?

If you can't pull the logs for any reason, a packet capture will do the same job.

Only thing I can think of that directly relates to any sort of length, is that if you were running close to a fragment size limit, a longer password could trigger an issue.

Start with the log files before tweaking your config though.
