NIS passwd file is never updated with new users

[Thomas]

Hi

I've configured a NIS master server as descriped in the freebsd handbook
(http://www.freebsd.org/doc/handbook/network-nis.html). I removed all
super and system users from master.passwd in /var/yp, chmod 600
master.passwd and initialized my NIS master server without any errors.

ypcat passwd showed me a correct list with users. But the NIS password
db will not be updated if i add any new user.

I tried:
pw useradd test1234
cd /var/yp
make myusers
`myusers' is up to date.

My new added test1234 user is not added to/var/yp/master.passwd or
/var/yp/passwd but test1234 is in /etc/passwd and /etc/master.passwd.

How can i updated my NIS master.passwd?

System Information:
It's 7.2-RELEASE-p6 (amd64)

my rc.conf for NIS:

nisdomainname="myusers"
nis_server_enable="YES"
nis_yppasswdd_enable="YES"
nis_ypxfrd_enable="YES"
