Unfortunately it is not possible to use DNSMasq as a backend for the --setup-dns option. This option depends on a bind specific LDAP backend (bind-dyndb-ldap) and there is no equivalent plugin for DNSMasq. > I am really hoping someone might be able to give me a few pointers in > replicating the IPA named configuration in DNSMasq. If you want to use DNSMasq you will have to create an appropriate zone and fill it with the necessary SRV, TXT and A records. When you do not use --setup-dns the FreeIPA install script generates an example zone file. You can use that file to configure DNSMasq. Keep in mind this will also mean no Dynamic DNS updates nor LDAP updates are possible so you will have to manually mange your DNS for each replica and client you add to the FreeIPA domain. Another alternative is to use bind for DNS and keep using DNSMasq for the other services.
