[unclug] Redirect 80 ---> 443 with Apache? -- credentials encrypted?

I have a similar situation, I think you can use tcpdump to check this out:

tcpdump dst port 443 and  host lark.cs.unc.edu

You should see the traffic on 443 and not 80 after submitting
the user/password.

Another way to check this out that works for me, (I think):

I know what you mean about not seeing the https or the security icon, I 
have seen this similar scenario on other web sites including my own
and am not sure if my user/passwe is encrypted, I think it is.

For example, I have a .htaccess file:

RedirectMatch (.*)$ https://lark.cs.unc.edu$1

AuthUserFile /var/www/.htpasswd
AuthName 'Computer Science UserID:'
AuthType Basic
require valid-user

I do a -DINSECURE define on my port 80 server and a -DSECURE on my port
443 server. When I hit the port 80 server the .htaccess file
re-directs me to the port 443 but it does not show the https link etc.
when prompting for the user/password.

But, I have a ssl certificate that does not match my https host name, 
mozilla complains about this with a popup before it pops up the 
user/password box which proves to me it did get re-directed to the ssl 

Setup an alias on your https and redirect to the alias and see if
it commplains about the hostname not matching the certificate name
before the user/passwd prompt.
