use admin domain as user domain

[piziwate]

Hello !

Thank you for your answer.

I put :
SERVER_HOSTNAME = host-srv01

and changed my /etc/hosts
127.0.0.1 host-srv01.local localhost
xxx.xxx.xxx.xxx host-srv01

But it still not working. The admin.domain.tld is not resolved !!

Code:

host-srv01:~# nslookup domain.tld
Server:         127.0.0.1
Address:        127.0.0.1#53

Name:   domain.tld
Address: xxx.xxx.xxx.xxx

----------------------------------------------------
host-srv01:~# nslookup admin.domain.tld
Server:         127.0.0.1
Address:        127.0.0.1#53

** server can't find admin.domain.tld: SERVFAIL

An idear ?
