Re: DNS resolve problem with ping but not nslookup

Something with AD configuration?

I got the same problem with my two new virtual redhat and suse. It was
the directory LDAP client which was the problem. Now both servers are
running correctly.

If using linux (redhat or suse):
look at nsswitch.conf & ldap.conf

1) put "bind_policy soft" in /etc/ldap.conf
2) nsswitch.conf must minimum have:

passwd: compat
group: compat
hosts: files dns
networks: files dns
services: files
protocols: files
rpc: files
ethers: files
netmasks: files
netgroup: files
publickey: files
bootparams: files
automount: files nis
aliases: files

3) reboot
4) check with: ping, nmap localhost.
5) now you can enable your ldap client again. (RH: authconfig ; suse:
yast2 ldap). It will modify your nsswitch.conf
