[Djigzo users] How to overide global static password preference?

Hi Our global preferences are set to static password with -1 validity interval. If we try to create a domain or a user with random password (password is blank and uninherited, validity interval is set to 0 and also uninherited) djigzo does not accept these settings and reverts to global password  with inherit checked. If password is not blank then it is set as static and never changes. The only way to create a random password user is to temporarily change global preferences to random, create a user and then change global preferences to static again. Are we doing something wrong?
