I had a similar issue in the past
SSSD had a higher init.d/chkconfig start number than network … so it was starting before
the network
Check the starting order of the init scripts to make sure:
lrwxrwxrwx 1 root root 14 Jan 15 2015 /etc/rc5.d/S26sssd -> ../init.d/sssd
lrwxrwxrwx 1 root root 17 Nov 17 2014 /etc/rc5.d/S10network -> ../init.d/network

Hi List,
Facing another issue on RHEL-6. After server reboot, the sssd is unable to go online.

Looks like DNS issue but I am pretty sure DNS worked just fine. After sssd restart
everything goes just fine.
sssd-1.11.7-4.el6

Hello,
does this happen every time you reboot the server or was it one time event?
If you reboot the machine and network is not working SSSD will go offline, but it will
periodically try to connect to the LDAP server and will go online when network/DNS starts
working again.
