I have encounterd some issue when regional settings is set to german, for the Project Client.
Basically the list separator for the german language is ";" (could be for other languages as well) instead of "," and when someone tries to add ressources for a task he must enter usually "firstname ; lastname"
Here is were the problem arises, the clent will take firstname and lastname as 2 different ressources, instead of one, and will separate the names, and when trying to save the project on the Project Server the Ressouce won't be recognized.
Changing the separator in the Regional settings wouln't be a good idea for Excel Users and not only as it could interfere with formulas and other excel costumizations.
Background : When doing an AD Sync, the username separator for Project is by default ";" as per following KB Article:The following KB article applies to all Project Server versions including 2007 and 2010:How to troubleshoot Active Directory synchronization issues in Project Server 2003http://support.microsoft.com/kb/887025
List separator character
To solve this issue there are 2 Options:
Option 1: Change display name in AD
Option 2: Using following query with the Project Server Published database we are able to replace the display name separator character
Check for your Separator with the following query on the Published Database:select wadmin_ad_sync_replace_char from msp_web_admin=============================================
USE ProjectServer_Publishedexec MSP_ADMIN_SetADSyncReplacementCharacter @replacementCharacter = ', ' (you can replace it with comma or other characters but make sure you don't interfere with your regional settings characters)=============================================
Restart the server and trigger a AD Sync and after that the PWA user name should be in the format "lastname, firstname" when checking under manager users.
