Is there a switch I can add to the end of the dmt.exe to specify no SSo and point to a different server? Currently this shows Default and the incorrect environment. I cannot change the selections because SSO is selected and not let you change the input.
Open a command prompt where DMT.exe is located and run “dmt.exe -?”, or add the “-?” option to the icon temporarily to start DMT and to show you the command line options. There are plenty of them and -User, -Pass, -ConfigValue (this is probably easiest to set you own special DMT .config file) should all help you escape the SSO problem.
