Hello, when I try to add a workstation in a dhcp subnet I have the next error. But, my new client machine is well save.

 LDAP modify operation failed!

Object: cn=192.168.10.0,ou=dhcp,cn=dhcp,dc=labo,dc=opensides,dc=be

Error: Cannot modify object class (structural object class modification from 'dhcpSubnet' to 'dhcpService' not allowed, while operating on 'cn=192.168.10.0,ou=dhcp,cn=dhcp,dc=labo,dc=opensides,dc=be' using LDAP server 'ldap://192.168.10.200')
