Client ___ authentication failed
Is an error message logged when a client attempts to open a database with an incorrectly entered account name or password. It may not have anything to do with what happened--talk to your client and see if they had to enter a password a second time.
You'll need to look more closely at your user interface and try to figure out how this happened. Is this an instant web published database where the user used a web browser to access your database or did they use a fileMaker Pro client to access it? Is this a custom published database?
OK, I am glad the error message isn't anything too drastic. To answer your questions, the database IS hosted using IWP and it is a custom made layout. Is there something about this configuration that is not set up right? Thanks.
Don't know. If you had used custom web publishing with PHP or such, I'd suggest checking the code for that, but I can't conceive of how the data entered in the browser page for field 1 would mysteriously appear in a different field. Are there any scripts that might somehow have been involved? The one way I know of to get mismatched data and fields is with an Import records action that imports records from one table to another and fails to correctly map the target fields to the correct source fields and this seems highly unlikely for this situation.
