In our ASP.NET 2.0 application, we are using
ActiveDirectoryMembershipProvider that comes with ASP.NET 2.0 and following
the guidance on using it published by the patterns and practices team on MSDN.

Using the above model we create a user into our application by first
searching the user in Active directory and then assigning a proper role to
the user.

Everything works fine on production server but on the development server
when we search for a user, we get the following error message:

“Logon failure: unknown user name or bad password”

Both the production and the development servers are running ASP.NET 2.0 on
Windows Server 2003 and have the exactly same application running on both
servers with exactly same configuration on IIS 6.0. The SQL Server 2005
databases on both the servers are also exactly the same.

Could someone please guide us to resolve this issue?


Thanks in Advance,
Nam
