Re: dnsdomain schema missing in 389 Directory server - can not run PowerDNS LDAP backend

[Tomáš Brandýský <tomas.brandysky@xxxxxxxxx>]

Morgan,

there is no problem with converting the schema.
Like I wrote I managed to convert the PowerDNS schema but this schema is just extending 'dnsdomain' schema which is actually part of OpenLDAP and was part of 389 DS in the past. As dnsdomain schema is not part of 389 DS anymore all other schemas trying to use it can't be loaded either.

This is how PowerDNS extends dnsdomain schema which doesn't exist in 389 DS:

objectClasses: (
  1.3.6.1.4.1.2428.20.2
  NAME 'dNSDomain2'
  SUP 'dNSDomain'
  STRUCTURAL
  MAY ( DNSTTL $ DNSClass $ WKSRecord $ PTRRecord $  HINFORecord $ MINFORecord $ TXTRecord $ RPRecord $  AFSDBRecord $ SIGRecord $ KEYRecord $ GPOSRecord $  AAAARecord $ LOCRecord $ NXTRecord $ SRVRecord $  NAPTRRecord $ KXRecord $ CERTRecord $ A6Record $  DNAMERecord $ APLRecord $ DSRecord $ SSHFPRecord $  IPSECKEYRecord $ RRSIGRecord $ NSECRecord $  DNSKEYRecord $ DHCIDRecord $ SPFRecord )
  )

Tomas,

It’s been a while since I’ve done it but I seem to remember it being relatively straightforward to convert between OpenLDAP's and 389’s schema formats.  Have you made an attempt to convert the PowerDNS schema?

As I tried to google more information why this schema doesn't work with 389 DS I found out it uses 'dnsdomain' schema which comes with OpenLDAP (https://lists.fedoraproject.org/pipermail/389-users/2011-January/012721.html) and was removed from 389 DS many years ago.

If there is no way to migrate PowerDNS LDAP data from OpenLDAP to 389 DS the whole project of migration to 389 DS would need to be reconsidered. Nevertheless I don't understand why such a worldwide popular DNS server which PowerDNS surely is couldn't be used with 389 DS LDAP implementation which is also quite popular.
