Otherwise, you're going to have to use a wildcard cert on the ISA itself. Regarding the use auth, all you need to do is use RADIUS for the non-trusted AD. FBA can resolve accounts with RADIUS jes' fine, jes' fine... Make sure you have SP2 and the 916106 rollup installed and take a read here: http://support.microsoft.com/kb/884560 ------------------------------------------------------- Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles! ------------------------------------------------------- -----Original Message----- From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Mathieu CHATEAU Sent: Saturday, July 01, 2006 04:07 To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] ISA 2004 as OWA FE and multiple domains http://www.msexchange.org -------------------------------------------------------Hello exchangelist, I am looking for a temporary solution. Here is the setup: One ISA 2004 acting as reverse proxy. One AD with exchange 2003 One AD with exchange 2003. I must provide OWA & ActiveSync access to users in both domain from the ISA 2004. There isn't domain trust between domains up to now. I am thinking about doing something like: webmail.XXX.com/Exchange/ webmail.XXX.com/Exchange2/ or: webmail.XXX.com/Exxchange/ webmail2.XXX.com/Exchange/ The second looks much easier, but i only have one SSL certificate, so would have to self generate for webmail2. I need a temporary workaround, all users will be in one AD in a month. I am using formbased on ISA. Thanks in advance !
