In some AD environments, there could be multiple UPN domain suffixes setup in a mixed AD hosting setup and the UPN prefix names might not be unique in those cases.
Normally FileCloud uses the UPN prefix names as the usernames and if they are not unique it causes problems identifying the user account correctly.
Therefore if you want FileCloud to authenticate using these kinds of environments, you need to setup the AD connection information slightly differently. In those cases, the account sAMAccountName will be used as the user id.
- Disable the checkbox "Users have the same UPN Account Suffixes"
- Set the 'AD Logon Name Prefix' parameter, this is the prefix used in the non-editable part in the User Logon Name (Pre-Windows 2000)
Users can login using either their email or sAMAccountName.
