[Bug 673427] [NEW] DHCP with LDAP config should load class definitions first
Public bug reported:
Binary package hint: dhcp3-server-ldap
Take as example the following dhcpd.conf (just as example, it's syntax
is not right):
global parameters...
class VoIP_Phones {
match if (substring (hardware,1,3)=00:04:13);
}
class Other_Clients {
match if not (substring (hardware,1,3)=00:04:13);
}
subnet 204.254.239.0 netmask 255.255.255.224 {
subnet-specific parameters...
pool VoIP {
allow members of VoIP_Phones;
deny members of Other_Clients;
pool-specific parameters...
}
pool VoIP {
deny members of VoIP_Phones;
allow members of Other_Clients;
pool-specific parameters...
}
}
If you want to have such kind of configuration LDAP based, you would
create corresponding LDIF files and load them in the LDAP.
But - and that's tricky - you need to ensure to load all classes that
get referenced by the pool declarations later get loaded into the LDAP
before the pool declarations.
In other words - DHCP does not automatically load class declarations
first. If you you first save the pools into LDAP, followed by the
classes, DHCP will throw an error on restart because it finds the
reference to the class before the class declaration itself.

Uuups, of course it's
class Other_Clients {
match if not (substring (hardware,1,3)=00:04:13);
}
** Description changed:
