Squid3 (latest download) accel does indeed allow sequential username/password authentication with OWA when the same username/passwords are used, however, I had to do two additional things.
1. Change the accel realm to the realm that OWA is in (NT Network). auth_param digest realm 'user_nt_realm' 2. Add cache_peer option to forward credentials (login=PASS) cache_peer #.#.#.# parent 80 0 no-query originserver name=owa.server.tld login=PASS I still get a second popup asking for username and password but I think the login=PASS forwards the realm because now it works and without it it didn't. SSL to the accel works with http://accel.server.tld:443/exchange but does not work with https://accel.server.tld/exchange with the following: cache_peer #.#.#.# parent 80 0 no-query originserver front-end-https=auto log errors produced indicate a header problem: 2003/07/30 23:11:27| parseHttpRequest: Requestheader contains NULL characters 2003/07/30 23:11:27| clientParseRequestMethod: Unsupported method 'L' 2003/07/30 23:11:27| clientProcessRequest: Invalid Request Is there something that I can do so that https:// will work, as well? -- Jim Flowers<[EMAIL PROTECTED]>
