Im looking for some "cheap" or free (open source) AD adminsitration software....

We have about 15 individual domains (dont ask why we havent centralized) to administer, and at the moment pretty much manually add/remove users as they come and go..... which is unfortuntely quite often as we run courses so students come and go all the time.

Im in the process of using ADUser to help cut down on some of the time adding users, but overall Im after something that will allow multiple domain administration with options of bulk user importing from CSV etc.

I have found ADManager Plus which is great, but the free version is limited to 100 users and 1 domain. We would look at the Standard/Pro version, but they have an annual fee system which is a tad annoying.....

Does anyone know of anything that will allow the above at a "cheaper rate" as it were ? :)

TIA
