help!!! Login failed for user .

[Ken]

I used two datasource but same connectionstring.
When I used to retrieve data then it works fine (impersonation correctly).
However, when I used login asp.net control, it returned an error (below).
"Login failed for user 'USERNAME'".

Anyone has idea why I got this???

Well, you haven't provided any information about either what your connection
string looks like or what kind of authentication you are using. But one thing
is for sure - whatever credentials you are getting from the login control,
they aren't getting you into your database. So the solution should be
self-evident.
