[Users] DNS reverse configuration

[Eduardo Ramos]

Hi all!

I'm trying to connect my ovirt-engine in a samba4 server. Samba4 is 
ActiveDirectory complaint. But when I use engine-manage-domains, it 
returns me a strange message:

[root at ovirt-dir eduardo]# engine-manage-domains -action=add 
-domain=gsr.inpe.br -provider=activeDirectory -user=Administrator 
-interactive
Enter password:

Error: Authentication Failed. Error in DNS configuration. Please verify 
the oVirt Engine host has a valid reverse DNS (PTR) record.. Problematic 
domain is: getconnection: driver class 
name=org.postgresql.xa.pgxadatasourcegetconnection: 
url=jdbc:postgresql://localhost:5432/enginegetconnection: considering 
encrypted passord. secdomain=encryptdbpasswordexecute: beginning 
execution of action action_get.fetching key=domainname ver=general
Failure while applying Kerberos configuration. Details: Authentication 
Failed. Error in DNS configuration. Please verify the oVirt Engine host 
has a valid reverse DNS (PTR) record.

Using host command, I got the following results:

[root at ovirt-dir eduardo]# host ovirt-dir.gsr.inpe.br
ovirt-dir.gsr.inpe.br has address 150.163.80.125

[root at ovirt-dir eduardo]# host 150.163.80.125
125.80.163.150.in-addr.arpa domain name pointer ovirt-dir.gsr.inpe.br.

[root at ovirt-dir eduardo]# host -t srv _kerberos._tcp.gsr.inpe.br
_kerberos._tcp.gsr.inpe.br has SRV record 1 0 88 samba4.gsr.inpe.br.

[root at ovirt-dir eduardo]# host samba4.gsr.inpe.br
samba4.gsr.inpe.br has address 150.163.73.109

[root at ovirt-dir eduardo]# host 150.163.73.109
109.73.163.150.in-addr.arpa domain name pointer samba4.gsr.inpe.br.

As you can see, it is everything ok. No DNS problem.

Someone have any idea?

Thanks.
