Case Sensitivity in Group and Application Role Names
By default, the human workflow system is case insensitive to user names. All user names are stored in lowercase. However, group names and application role names are always case sensitive. User name case insensitivity can be changed in Oracle Enterprise Manager Fusion Middleware Control.
Caution:
Only change this setting after performing a new installation. Changing this value on an installation that is actively processing instances, or has many instances in the database, causes serious issues.
To change case sensitivity:
If you are upgrading from 10.1.3, which by default was case sensitive, set caseSensitive to true
for the system to be the same as with 10.1.3.
