Data Provider is offline

[Michaël Van de Borne]

Hi all,

So I have 2 Centos7 hosts, with same sssd and nsswitch configs.
One does find the users in IPA, and the other doesn't.
Looks like the Data Provider is offline.
I sent the SIGUSR2 signal to sssd which is supposed to bring him online. 
Didn't help.
The hosts can resolve the IPA server hostname. SElinux is enforced. 
Iptables is disabled.

here's my sssd.conf

[domain/vgt.vito.be]
cache_credentials = True
krb5_store_password_if_offline = True
ipa_domain = vgt.vito.be
id_provider = ipa
auth_provider = ipa
access_provider = ipa
ipa_hostname = epoddev8.vgt.vito.be
chpass_provider = ipa
ipa_server = _srv_, epoddev5.vgt.vito.be
ldap_tls_cacert = /etc/ipa/ca.crt
debug_level = 7
[sssd]
services = nss, sudo, pam, ssh
domains = vgt.vito.be
[nss]
homedir_substring = /home
debug_level = 7
[pam]
[sudo]
[autofs]
[ssh]
[pac]
[ifp]

here's the log of sssd_nss.log
