More on IMAP

I have been attempting to implement IMAP authentication in my
organization— it has been nothing but a nightmare. Take this simple
function (It’s quick and dirty for testing purposes… definitely a
nasty recursive call in there)

def authenticate_user(u, p)
imap=Net::IMAP.new(‘imap.server.net’, 993, true)
isvalid = imap.authenticate(‘LOGIN’, u, p)
return isvalid
rescue Errno::ECONNRESET
authenticate_user(u, p)
rescue
false
ensure
imap.disconnect
end

On any platform in a flat .rb file: works 100% of the time
On Mac OS X in a RoR instance: works 100% of the time
On Ubuntu 8.10 (x64 & i386): works, but sometimes throws the
Errno::ECONNRESET error which must be rescued
On SuSE 10.2 (i386): will not rescue Errno::ECONNRESET error

What is going on?! Why do RoR instances on Linux hate Net/IMAP when
everything functions fine within Ruby itself or within OS X. There is
clearly some kind of issue with OpenSSL, but I’ve tried compiling from
source and cross-compiling Ruby on top of it.

It should be noted that my OS X box is using 1.8.6 darwin version of
Ruby, whereas my Linux servers are using 1.8.7 linux versions. Should I
try downgrading Ruby?

Any suggestions would be greatly appreciated.

Here are more errors for your pleasure:
