Please reread the install docs, the part specific about setting up the authentication information. Depending on the backend used:

• TracCgi#AddingAuthentication
• TracModPython#ConfiguringAuthentication
• TracStandalone#UsingAuthentication

I'm leaving this open though, as I think we get that installation issue reported often enough and that maybe it's time to output a more friendly and informative message to the user.

Error message improved in r4160 (trunk) and r4162 (0.10-stable).

Hopefully we'll get less messages of this kind in the future ;)
