setup ipa server with DNS when domain is managed by existing DNS server but not yet managing the reverse zones I want to configure

[Rob van Halteren]

Hello,

I have seen more threats like this but not exactly this topic.

I am setting up an IPA server in a existing internal domain on a B-class network range . I have already a DNS server running for this domain, but it holds only a C-class network range. 
I tried to setup the IPA server with the "ipa-server-install --setup-dns --no-forwarders  --auto-reverse --allow-zone-overlap" options but this does not work and results in the disability to create PTR records for any network range in my domain. + it than needs the existing DNS server as forwarder to be able to resolve global addresses.

I intent to install the IPA server as qualified DNS server for my domain , next to the existing DNS server and when setup, decommission the existing  
DNS server.

Any help would be appreciated

Thanks. Rob.

I solved this , by omitting the --auto-reverse option.

I than had to manually take care of the DNS entries of both servers so they did not conflict.
Not a nice solution, but it helped me in this case.
