Re: perl one-liner, is it possible?

Sure!

perl -i -e '$/=\32000; while(<>) {s/\s{2}//sg;print $_;}' oid.ldif

Change the input record separator, so that instead of the reading of the file breaks on new lines, we read chunks of data.
Next, just substitute the two white space characters ('\n' and ' ') with nothing and the lines get concatenated.
