TMG 2010 asks for credentials twice in OWA
Posted on 2013-12-10
I have replaced the old TMG 2010 server with a new one, and now Activesync doesn't work and OWA asks for credentials twice before letting me in.
I have checked that there is only basic and windows integrated authentication on the Exchange server, and forms based on the TMG.
There were some trouble with the certificates, and I had to re-key them, this is maybe some of the problem...
