Hi there,

Can someone help me understand how I can configure a Sql Server 2008 filestream share so that it can be used on a web site that uses forms authentication and sql server authentication?

Well, you don't need a share per se. It is "owned" by sql server. SQL Server 2008 can store blobs in its own private NTFS namespace rather than in the database itself. The database contains pointers to that namespace (and it's contents are named for SQL server so no longer represents the original doco name).

So, it is the SQL Server (and agent) accounts that need access to that folder, and best via a domain accout for those services. The advantage is that SQL server manages it and you can hide all of it from the outside world.

There is a really good whitepaper : http://msdn.microsoft.com/en-us/library/cc949109.aspx

And a discussion : http://blogs.msdn.com/rdoherty/archive/2007/10/12/getting-traction-with-sql-server-2008-filestream.aspx

And an example : http://msdn.microsoft.com/en-us/library/cc716724.aspx  and http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2008/09/08/10729.aspx

And everything else you ever wanted to know about filestream (as a developer) : http://msdn.microsoft.com/en-us/library/bb895234.aspx

Sorry about the links, but they really are the best answers...

I actually implemented FileStream in a web application. The only downside is that I use integrated security and there everything is working perfectly. However I have to consider using forms authentication and sql server authentication and that's were I get a access denied error. I want to workaroung that problem but still use forms and sql server authentication.

Well, that is going to be fun, because "to access the FILESTREAM BLOB by using Win32, Windows Authorization must be enabled." (from the manual)

So, you will need to create a domain user, give them access to those folders / directories add them or associate them with a SQL login and then login using that SQL login. The only account that is granted NTFS permissions to the FILESTREAM container is the account under which the SQL Server service account runs. So, you MUST use the OpenSqlFilestream APIs

In other words, it is impossible to take advantage of FileStream without using Windows authentication. Thanks any way.
