I am authenticating my users with the following configuration (simplified)
<AuthnProviderAlias ldap server1> AuthLDAPURL ldap://server1/whatever?uid?one? </AuthnProviderAlias> <AuthnProviderAlias ldap server2> AuthLDAPURL ldap://server2/whatever?uid?one? </AuthnProviderAlias> <Location /> AuthName "Realm" AuthType Basic AuthBasicProvider server1 server2 AuthzLDAPAuthoritative off require valid-user </Location>
Is there any way I can know if which LDAP server my user was authenticated from? When the authentication is sucessful I'd like to set an HTTP header (something like "SourceLDAPServer: server2") to be able to tell which server the user was valid in. Is that possible with Apache 2.2.x?
