I would create and set a password according to RFC-3062, a little Perl
script could do this and mail the password to the trial user. I would
not allow a user to modify her pasword in a trial period.

Policy would be
pwdAllowuserChange: false
pwdMustChange: false
pwdSafeModify: false
pwdMaxAge: according to your requirements.
