ZENWorks for Desktops 7 with SP1 on Novell OES Linux

We have this error in our awsi.log:

Aug 22, 2006 10:49:30 AM OS = <linux>
Aug 22, 2006 10:49:30 AM FindImport Policy serverDN = CN=servername.O=company

Aug 22, 2006 10:49:31 AM No import policy found.

No workstations will import!! I've checked all TIDs and all our policies. We have an identical ZENWorks setup in another tree. Conf files and everything is the same and in this setup the import works fine.

Kind regards,
