Once you enable WAS security on the WAS instance to which the TAM WPM was deployed you will see that you will be prompted for a username and password before even getting to the WPM homepage. That’s WAS security kicking in.
In order to disable it navigate to the WAS console then Applications -> Enterprise Applications -> TAMWPM -> Map security roles to users/groups. Uncheck everything under “All Authenticated?” and check everything under “Everyone?”. Save and restart. The next time you browse to the WPM you will get to the WPM homepage without WAS prompting you for anything.
Oh yeah…probably not a bad idea to apply WAS & Java fixpacks…
