Hi Shantanu,
Thank you for your update, I've done my config a little differently and it
appears to work just the same. The relevant part looks like this:
<Location />
## ActiveDirectory authentication and authorization
AuthType Basic
AuthBasicProvider ldap
AuthName "R&D Galaxy Testing/QA Server"
AuthLDAPURL "ldap://my.server.com:389/OU=Users &
Workstations,DC=domain,DC=com?sAMAccountName?sub?(|(objectClass=person)(objectClass=group))"
# ...more AuthLDAP directives here...
RequestHeader set REMOTE_USER %{AUTHENTICATE_sAMAccountName}e
</Location>
<Location /datasets>
Order Allow,Deny
Allow from All
Satisfy Any
RequestHeader set REMOTE_USER "anonymous"
</Location>
## Static content and reverse proxy
RewriteEngine On
RewriteRule ^/static/style/(.*)
/path/to/galaxy/galaxy_dist/static/june_2007_style/blue/$1 [L]
RewriteRule ^/static/scripts/(.*)

RequestHeader to 'anonymous' regardless of authentication status. I think
following config should work (still testing). In our case it resides outside
of Location directive now. You may need to adjust it according to your
setup:
