FDM "Error: Can't authenticate user" when creating new apps

Question

We are experiencing the above error when trying to create a new FDM application, and cannot seem to get past it. The details are as follows:
- FDM manages to create the folder structure on the server fine, so suspecting SQL or HSS permissions/provisioning
- SQL database is not created
- Creating the SQL database manually beforehand does not help either
- The EPM Admin experiences the same error!
- No FDM logs appear to have been generated in C:\Oracle\Middleware\user_projects\epmsystem1\diagnostics\logs\fdqm
We were able to create FDM apps fine at some stage, but cannot now for some reason. Please let me know if you have any suggestions.

Answer 1

On the FDM server, from the Start menu, go to All Programs --> Oracle EPM System --> Financial Data Quality Management --> Load Balance Manager --> Load Balance Configuration.
On both the Authentication Providers tab and the Application Servers tab, you should see at least one entry. If you do not see an entry on either of these tabs, enter the appropriate settings on each tab, then go to the General tab and enter the password for the DCOM account. If, on the other hand, the original settings are intact, just go to the General tab and enter the password for the DCOM account. If you enter the correct password and do not get an error, then this verifies that the DCOM settings have not been corrupted.
