We're about to go into production with OWA2007 behind ISA2006. Our ISA servers are part of the domain - so we are using Windows authentication*not*LDAPS. http://blogs.technet.com/isablog/archive/2007/08/23/password-change-with-fba.aspx States "You must use an LDAPS connection to the LDAP server/dc" [ for Password Change to work on FBA with ISA 2006] So how do we do that when we're using Windows Authentication ? Do we need to setupan LDAPS connection just for Password Change ? Will that break/over-ride our existing Windows Authentication ? Many Thanks!
