I had trouble logging in but was finally successful by granting an existing auth_user superuser membership. I ran into the same "password must be 6 chars" error.
One thing I noticed is that it did not seem to pick up my auth_user table (I don't see it listed in the right side nav). I am using a custom auth_user table. Then was not able to access any table records with this error: Traceback (most recent call last): File "/Users/pbreit/web2py/gluon/restricted.py", line 192, in restricted exec ccode in environment File "/Users/pbreit/web2py/applications/init/views/plugin_instant_admin/list.html", line 65, in <module> if request.vars.get('sort_reverse') == 'false': File "/Users/pbreit/web2py/gluon/html.py", line 287, in URL args, other, scheme, host, port) File "/Users/pbreit/web2py/gluon/rewrite.py", line 112, in url_out acf = map_url_out(request, env, application, controller, function, args, other, scheme, host, port) File "/Users/pbreit/web2py/gluon/rewrite.py", line 1177, in map_url_out return map.acf() File "/Users/pbreit/web2py/gluon/rewrite.py", line 1115, in acf self.omit_acf() # try to omit a/c/f File "/Users/pbreit/web2py/gluon/rewrite.py", line 1067, in omit_acf if self.args[0] in self.functions or self.args[0] in self.controllers or self.args[0] in self.applications: TypeError: unhashable type: 'Table'
