When trying to log into any Identity Manager frontend, the error "Login for user <username> failed" - "Script assembly [script_name] not found in 'DialogScriptAssembly'." is displayed.
To resolve this issue:
1. On the local workstation, browse to: "C:\Users\[user_account]
2. Backup, and delete all sub-folders.
3. Browse to: "C:\Program Files (x86)\Quest Software\Quest One Identity Manager" and launch the "DBCompiler" to re-compile the database.
4. Once the database is compiled, the error should disappear.
