I do like the use of a configuration option to turn on hostname
verification.  And as you say there have been requests for this
feature in the past, but there have also been posts of patches
implementing it in the past (e.g.
by me, but sans the option bit :-).  I do have some questions though:

1. If I read this patch correctly it only checks CN, is that correct?
2. Is there any particular reason for not including SAN in the
verification as well?
3. Are the patches released under GPL?
