System SLES10 SP3, OES2 SP3 eDirectory 8.8

I try to insert DSFW in the NDS Tree , if I do it under Unit Organizational (OU=DSFW,O=TEST), there is no problem everything work correctly, I can insert in it a Xp Workstation with the Administrator account.

If I insert DSFW under organizational (O=TEST), when I insert a workstation I have an error with Administrator account (password policies error), I need to insert Xp with Administrator@dsfw.test to do it.

And the existing users can connect on the XP only after to have change a password (not very funny with 900 users)

Does somebody have this problem? Or any solution?
