Peter:
The SASL_README doc has a section about doing a telnet test of a PLAIN
SASL authentication. There are some methods suggested for generating
the base64 hash required to do the authentication, Of those two methods
one requires downloading a special utility to generate the auth string
and the other requires installing a perl module. I have a third suggestion:
echo -ne '\000username\000password' | openssl base64
This method is relatively easy to do, and will work with the programs
that are already readily available on most systems. I think it would be
good to add it to the docs.
This does not work for me. If you make a suggestion, be sure
to indicate what platform and shell this applies to.
Appears to work in bash and zsh; not in (t)csh. I quickly tested on
FreeBSD and Darwin. Likely related to handling of null byte/char.
Yes, sh (not bash) & csh ignore the \000.
Probably more portable using printf rather than echo, but I
don't have anything other than fBSD to try it on.
printf '\000user\000pass' | openssl base64
