Hi, We haven't gotten this working but I think that we've made some progress in diagnosing. First of all, by comparing to a different, working configuration, what I mentioned previously about the sequence of the two denies and the "Faking" log message is probably a red herring. From that other system that sequence is "normal" and messages with the authentication against the LDAP occur AFTER the "Faking" message. One of the things we noted, which we're not sure is significant or not, is that the requests are not GETs, but are CONNECT requests, so now we are wondering if maybe it's possible that Apache somehow is skipping the authentication if the request is a CONNECT request. I know that that is a long shot, but I figured that I'd ask.

We CAN already do username/password (Basic) authentication against the LDAP using something like: AuthType Basic AuthName "xyz" AuthBasicProvider ldap AuthBasicLDAPURL AuthBASICLDAPDN AuthBASICLDAPPassword Require valid-user and that works fine. However, if we use client certs and do the following: SSLVerifyClientCertificate SSLOptions +FakeBasicAuth AuthType Basic AuthName "xyz" AuthBasicProvider ldap AuthBasicLDAPURL AuthBASICLDAPDN AuthBASICLDAPPassword Require valid-user then it doesn't work. Looking at the Apache logs, what we see when this fails is: mod_authz_core: AH01626: authorization result of Require valid-user : denied (no authenticated user yet) then mod_authz_core: AH01626: authorization result of <RequireAny>: denied (no authenticated user yet) then ssl: AH02036: Faking HTTP Basic Auth header: "Authorization: Basic xxxxxxxxxxxxx" From the logging (as above), it seems like mod_authz_core is denying the authentication (because there is no authenticated user yet) BEFORE the Basic Auth "Faking" occurs, and thus, BEFORE the LDAP authentication occurs. Does anyone know if this interpretation of what is happening correct? And, if so, is there some way to configure Apache so that it does the authentication vs. authentication checking in "the correct" order/sequence? Thanks!
