Caused by: java.sql.SQLException: Login failed for user

Hey folks,

i have installed OO 10.20 and did a patch upgrade to 10.22.0001 and this was done using SQL server account .Now it has to configured to work with windows authentication . So i'm following Database guide 10.2x under that " Configuring HP OO to work with Windows Authentication " section and did the changes accordingly ,but after the doing the changes OO is not coming up .It's giving 404 error in the browser.

when i went through the logs i could see "Caused by: java.sql.SQLException: Login failed for user " .So is that the login issue of the Windows credentials ? I just wanted to double confirm before asking the customer to look into it and i have also encrypted the password to key that in the database,properties file
