Apache LDAP authentication prompts multiple times for login/password.

I am reposting this since I have not found a solution and never got a
reply on the original post.  I've seen through Google others with the
same problem, but never a solution.  I'm hopeful that someone knows
what's going on...

I am trying to use Apache LDAP authentication and proxying to make sure
users exist in our LDAP repository.  This is working, but the user is
always prompted to login multiple times.  In Firefox the users are
prompted twice for their login; in IE the users are prompted three
times for their login.

My conf file looks something like this.

ProxyRequests Off
ProxyPass / http://localhost:5000/
ProxyPassReverse / http://localhost:5000
ProxyHTMLURLMap http://localhost:5000 
http://1.2.3.4
ProxyHTMLURLMap http://localhost:5000 

http://1.2.3.5

<Location />
  ProxyPassReverse http://localhost:5000
  SetOutputFilter proxy-html
  ProxyHTMLURLMap /     /
  AuthLDAPEnabled on
  AuthLDAPAuthoritative on
  AuthLDAPURL "ladp://myserver:3268/DC=FOO

,DC=BAR,DC=COM?sAMAccountName?sub?"
  AuthLDAPBindDN 'ldapuser@xxxxxxxxxxx"
  AuthLDAPBindPassword "password"
  AuthType Basic
  AuthName "Login in using your domain login."
  require valid-user
</Location>

If you see a mistake in my conf file, or understand why this is prompting for multiple logins I would appreciate any advice.

Thanks,
