Workflow installation issue

Hi All AxPerts,

I am installing Workflow… When i was adding users in the user form in Ax, it was adding. When i close and reopen the form, there is no users name which i have added. If i try to add the same name again, it shows that the name is already added. I checked the sql database, there the added users are there. But in Ax, sysuserinfo table, there is no users. So, i cant able to find the mistake i have done…Plz help me to fix this issue…

Also, i am using Windows 2008 Server R2…I have created another instance and there also, the same error came…
