Debugging output is always a security exposure. Secure debugging wouldn't be all that helpful to the debugging process especially as seeing the plain text password may be the difference between solving a problem or not. Perhaps 'redacted' debugging output is what you're after (for posting to the mailing list). Perhaps you could add a radiusd flag for that and change the debugging output accordingly.

I understand that it is sometimes useful to display the plain-text password in the debug output; however, I consider this a security exposure. I’d like to see a configuration option (e.g., debug_show_passwords or something similar) with a default of no, that when set to false/no would write “********” instead of a plain-text password in debug output. Currently, modules rlm_ldap, rlm_pap, and perhaps others write the plain-text password in debug output.
Your thoughts?
