Free user import tool - password issue

Hello,

I am new in AD. We use in my shcool the User import tool from Solarwinds.

When I try to import my csv, everything is ok but the user is not enabled. The password is not working. I need to reset the password manually in AD to active the user.

I have to download 850 students so I really need this to work.

Do you have an idea to solve this problem?

Thank's a lot!

Fanny
