samba_dnsupgrade

[Aaron E.]

I'm working of the current post "redundant DNS setup with bind_dlz possible"

When I try to run samba_upgradedns I recieve the following error..

root at adc2--/opt/samba4/private\>> samba_upgradedns
Traceback (most recent call last):
   File "/opt/samba4/sbin/samba_upgradedns", line 31, in <module>
     import ldb
ImportError: No module named ldb

I've added /opt/samba4/lib/ldb and /opt/samba4/lib/private to ldconfig 
but this still did not change anything.. Any ideas what I'm doing wrong?
