run navision Sincronize

hi all we have a sql option for NF 2.60F and we implemented some code to force users to change their nf passwords every 30 days. having nf under sql, the users passwords are saved not in nf user table but in sql logins. how can i run the sincronize process in ‘unattended mode’ [:P] in order to update user passwords? i think we have to make a call to the xp_ndo_enumusersids extended procedure but i don’t know how… some ideas please [:D]
