I was in a lot of trouble due to this error for the last couple of days. I used the option of setting up Web Configuration for Master Data Service (SQL Server 2008 R2) from Configuration Manager.
The screen shot of it is as follows:
I was logged in using my domain user account, and I had used User Name as “domainuser” instead; the error message continuously popped up each time. My domain account has administrator privileges, but even that didn’t help at all. Any help will be greatly appreciated.
Application pool not valid
The user does not match a known account in Active Directory.
The user does not match a known account in Active Directory
First of all start with making a local user and put this user in the admin group privileges so that it has all the rights an admin has.
Create a new login in SQL and access the rights to access the SQL server databases that you are using with the application.
Enter the new user name that you have just created.
If it grants you the access then it means that there is something wrong with that user which you are trying to access. So it is better to delete that user and put those user permissions to a new user that you will create to tackle this problem. Actually it will help you also to see which permission is causing the problem.
