Hi guys
this is sort of a follow up on Cannot get DHCP to work. I got dhcp server working last time but without ucs@school and I want to use ucs@school, so I’m not sure why dhcp is screwed up when this package is installed and no matter what I do to get dhcp working univention-dchp keeps being down and can’t get the damn service up
I’m on version 4.3-3 errata390
single server environment
looking to setup ucs@school
dc server name is optiplex
server’s ip is 10.20.20.24
the network to be served with dchp service is 10.20.20.0 with ranges from .24 to 254
domain is inscope.local
school name is icope
I got 2 dhcp services, one setup under the domain object and another one setup under school object. under each there’s a server called optiplex and subnet which 10.20.20.0 / 24 with ranges from .25 to .254, no pools were setup.
here are the logs

I’ve understand that with ucs@school I’m supposed to set my dhcp entries under the respective dchp container for the school, that’s why i setup anther dhcp service there with it’s respective server and network
and I’ve been playing around with dhcpd/ldap/base in ucr and I set it last as :
cn=optiplex,cn=inscope.local,cn=icdhcp,ou=icope,dc=inscope,dc=local
which I figured must be wrong…but that’s just me trying out. (I’m sorry I’m stil a newbie at ldap)
Any help would be greatly appreciated otherwise I might have to for another AD/domain controller option but I really like yours.
Thank you in advance.
