Database Logon Failed (ASP.NET/Crystal Reports XI R 2)

Posted on 2008-10-03
Last Modified: 2013-11-07
I have a crystal report with several subreports linked to the main report via a parameter, in an application. Whenever I am trying to convert it behind the scenes into a PDF, it does the job just fine on my local machine. The problem is that it throws a database logon failed exception on the server and I have no idea what else I can do to make it work...

Please, help!

Try commenting out line 41.

You are setting the logon information for each table.  You may be overriding it when you set the report document logon info.

I think I already tried that and decided to keep it there because it actually made it possible to login to the DB on my local machine... For some reason, it doesn't work the same way on the server... It seems that ApplyLogOnInfo method doesn't work...

Where do youopen the report document?

Are the logon values set correctly?

The report is being opened in the browser. The logon values are retrieved from the web.config, and I already tested those values by logging into the SQL Server with those credentials. I am not sure why I am getting this exception, since I am providing all the information required for successful login... At least, I think so.

I would try three things.
  1. try making sure that your data souce (if it is not localhost) uses the ip address of the machine, if you are using a dataset and setting the report source that way then make sure your Data Source key in your connection string value is setup like this: Data Source=tcp:,1433; User ID= yada yada).
  2. try looping through your subreports the same as you do now and instead of using the tables logoninfo just set each subreports connection info like this:

    for(int i=0;i<reportDoc.subreports.count;i++)
  3. Make sure that the server has both the same crystal decisions dll's as your local machine and also make sure that if your report uses the SQL Native Client ADO connection type that the SQL Native Client is actually setup on the host machine.  I did a project once that did not have the native client setup on it and it continuously threw logon exception errors.

i don't know what happened on my previous post but the code was supposed to look like this:
for(int i=0;i<reportDoc.subreports.count;i++) {

I solved the problem by implementing the push approach and embedding the subreports into the main report instead of using pre-existing reports as subreports. This way I made sure that all the subreports and the main report used exactly the same connection.

SetDatabaseLogon does not work for subreports
