'some error' does not actually help us to solve your problem. this is
redhat specific and has nothing to do with kerberos or auth. whatsoever
at this stage. look at the redhat docs (which used to be very good -
last one i used was 'shrike' :) ) for the troubleshooting of apache SSL

to answer your question: for apache auth_mod_krb SSL is recomended,
however not necessary. the fact is, it would work without it, but it's
definitely something you do not want to do. without SSL your kerberos
passwords will fly to the web server in cleartext (yes) and therefore
totally compromise your kerberos infrastructure (all your kerberized
services use the same useraname/password yes?)

apart from that, if your goal is to implement SSO solution (so that your
users will use kerberos TGT rather than password -but you never know
what will user do ;) ) the firefox (and IE) plugin is configured to
authenticate only to kerberos enabled websites over SSL - you would have
to override this in about:config setting for each of your URL's in
firefox (no idea for IE).

summary: you want SSL

there is a nice docs here (recommend reading through)
