authentication/db connection issues with new setup

Hi,
I've pretty much just thrown together a reporting services (2005)
configuration which connects to a mature sql server 2000 database held
elsewhere. Forgive me for probably not having too much of a clue
about how things should be set up, but I had a go.
I'll get straight to the problem.. that is I can view reports from the
machine running the server, using my own credentials or those of
someone else (tested by running IE7 under an alternative account on
the domain).
However, when using those same user credentials but from a different
machine, I get the following error:
An error has occurred during report processing.
Cannot create a connection to data source 'dsTachyon'.
Login failed for user '(null)'. Reason: Not associated with a trusted
SQL Server connection.
Any ideas as to what would be causing this?
cheers,
ChrisMy guess is that it's a "double hop" authentication problem.
You can connect directly to the db when you're on the server, which is a
direct connection. But when you're trying to connect to the db through the
report server, you have one connection hop from your pc to the report
server, and one hop from the report server to the db server. This is called
a double hop.
There are two ways of fixing it.
1) You can connect to the db with a static account that has read access to
the db you get your data from. Instead of using Windows Integrated
Authentication, you use "Credentials stored securely in the report server".
This can be either a SQL account or a Windows account. If you use this, make
sure you're encrypting the data in your report database, in order to encrypt
the password you add.
2) Configure the report server and the db server to use Kerberos, to allow
the credentials to be sent from your pc through the report server to the db
server.
If you want to use Kerberos, start by reading
Configuring Authentication for Reporting Services
http://msdn2.microsoft.com/en-us/library/bb283249.aspx
Specifying Credential and Connection Information
http://msdn2.microsoft.com/en-us/library/ms160330.aspx#
And
Configuring Constrained Delegation for Kerberos (IIS 6.0)
http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/df979570-81f6-4586-83c6-676bb005b13e.mspx?mfr=true
You also need to make sure Anonymous Access to the Report Server web
application is not allowed.
My suggestion is to first see if you're able to connect to the data with the
first setup (using a static account). If it works, you should use Kerberos,
as this is a more secure solution. If it doesn't work with a static account,
you might want to work out why before setting up Kerberos, because it's
usually easier, but less secure to make it work with a static account.

Thank you! Great depth to your reply, I've tried the static account
solution and that works so I'll give Kerberos a look.

Authentication mode / configuration issue

I'm having a little issue here with the MSSQLServer service which installs as part of the BlackBerry Enterprise Server. I can connect to it and run queries on it via Query Analyzer, but when I attempt to have a PHP script query against it, I get an error stating that the login failed because the user is not associated with a trusted SQL connection (severity 14). I've seen this before with other servers, and it was always a result of the server not being in mixed authentication mode.

So the question is this: How do I change it? There doesn't appear to be an Enterprise Manager or anything equivalent installed. Digging through the SQL Server folder, the only thing I saw that might have been useful is the SQL Server Network Utility located at Program Files\Microsoft SQL Server\80\Tools\Binn\SVRNETCN.EXE. This utility appears to only let me disable/enable protocols however, nothing about authentication.

I checked the Service Manager as well and didn't see anything of use there. Any ideas how I can do this?

It looks like I might have figured this one out. Using a copy of Enterprise Manager that I had installed on my machine, I added the MSSQL server installed on the BlackBerry server and changed its authentication properties that way. It looks like I'll have to tweak with some permissions for the individual databases but I think I've got it now.

Attempt to fetch logical page error

Hello,
I have recently moved some packages I had been working on from my development to production environment. Having come across many configuration related errors, I believed my latest one to be of this type. However I'm recieving one I've never seen before:

"Attempt to fetch logical page (1:95152) in database 8 failed. It belongs to allocation unit 72057594043301888 not to 72057594045661184.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly"

This package works fine on the development db, however I don't even know where to start tracking this issue down. Any thoughts?

Thanks,
Adrian CrawfordI just googled that message and got a link to an article by Bob Dorr who works for PSS supporting SQL Server.
In other words - I suspect this is a SQL Server engine problem, not a SSIS one.

-Jamie|||This sounds like you have a database problem. If it is SQL Server then you should probably post this to the relational engine forum. Again if this is SQL Server, you might try running DBCC on the database to see if that shows any problems.

Matt|||Thanks for the responses, I'll see if anyone knows about this in the database engine forum.
