We have had this issue where out WCF invokes antother WCF. We are using SSL for securing the transport and are using client certificates for authentication. We get: Could not establish secure channel for SSL/TLS with authority 'XXXXXX'.
If we run Internet Explorer on that machine, with the service account that is dedicated to run the application pool, the WCF starts to work. Hence we thought that there was an error with the user profile. The solution was to set Load user profile to true in the application pool, my question is..... why? Can't I mark the account as a service account in the Active directory and then get correct user profile loading? Is there another way to accomplish user profile loading? Preferably a setting in the active directory, since the application is going to be installed in several servers etc.
