[Freeipa-users] Recommendations for FreeIPA implemenation in existing organization

Hello, I'm planning to implement FreeIPA in an existing organization that is providing services - DNS - Active Directory - LDAP - Certificates My question for the experts is: What is your best practice / recommendation for implementation of FreeIPA considering the existing services? Should I simply *not activate* services in FreeIPA that already exist, e.g. DNS, Certificates? Regards Thomas
