We have 3 eDirectory trees connected via IDM2.

I have just installed the licences supplied by Novell, and on 2 of the
trees they are installed fine, however on the third tree it continually
tells me that activation is still required and that:

"This software is being used under an evaluation license; your right to
use the software will expire after a period of time specified in the end
user license agreement. To use this software after the evaluation
period, you must purchase a license, and then obtain from Novell and
apply a Product Activation Credential. For information on how to obtain
licenses to Novell products see
http://www.novell.com/products/howtobuy.html "

Any ideas?
