Did you reboot after the change?  Did you see the ldap connection
problem before or after the reboot?

When I do a debug run of subnet-change using '-n 10.20.0.0/24', I get
these translations:

N: 10.0.0.0 -> 10.20.0.0
N: 10.0.0.1 -> 10.20.0.1
N: 10.0.2.2 -> 10.20.0.16
N: 10.0.16.20 -> 10.20.0.128
N: 10.0.31.254 -> 10.20.0.254
N: 10.255.255.255 -> 10.20.0.255

No-where do I end up with 10.20.158.203.  Something else must have
gone wrong with your test.  I have no idea what could cause this.

I suspect it worked but you forgot to reboot.  At least it worked for
me to change the subnet.
