We're having the same problem. We are running FMSA (7.0v3) on a Win 2003 Standard virtual server, with external authentication enabled (against Microsoft Active Directory) and IIS 6.0. We are creating local groups on the server and adding the AD users to those groups; then adding those groups to the FM databases and assigning those groups privilege sets w/i the database. We also enabled encryption via SSL and generated a server certificate. When I try to log into the sample config db via web browser from a remote client (with the guest access TURNED OFF), I get a uname/password prompt. When I put in a correct username and pwd combination, the dialog pops back up and fills in the IP address of the server machine as the "domain" for the user (e.g. 000.00.000.000username). Putting in the AD domain preceding the username (e.g. ADusername) doesn't work either. We're not sure if this is an SSL problem. IWP is enabled for the db in question and my user account is assigned Full Access Privilege (and Full Access has the web extended privilege assigned). Anyone have any thoughts? Thanks!
