If I take the rewrite out of the <location> block then NTLM auth fails as the username is re-written and isn't a valid corporate username. On the plus side, If I just set "RequestHeader set REMOTE_USER smithiesr" then I get logged in as I should.

Put it in the global configuration file, after the <Location> part, but before the proxy statement. Also, the exact incantation that worked for me (after many many trials and errors) is: === RewriteRule . - [E=RU:%{LA-U:REMOTE_USER}] RequestHeader set REMOTE_USER %{RU}e === It's voodoo (to me) because it probably has something to do with deep apache internals, relating to execution order of the authentication module vs the "mod_rewrite" parts (and the "LA-U" [Look-ahead] thing sure doesn't help to make it clearer...). -gordon ======================================================================= Attention: The information contained in this message and/or attachments from AgResearch Limited is intended only for the persons or entities to which it is addressed and may contain confidential and/or privileged material.
