[web2py] mssql connect

[patrick moon]

I'm using the doc suggested connection string:

db =  DAL('mssql://shxxx:shaxxx@POPE:1433/xPAC')

and this is the error I'm getting:

Traceback (most recent call last):
  File "gluon/restricted.py", line 192, in restricted
  File "C:/_dev/temp/web2py/applications/welcome/models/db.py", line
18, in <module>
  File "gluon/dal.py", line 3981, in __init__
RuntimeError: Failure to connect, tried 5 times:
'NoneType' object has no attribute 'connect'

Appreciate any help....
