[Freeipa-users] Free ipa Configurations

Wed Nov 12 03:09:45 UTC 2014

I have another question, well I've achieved the state where I can't log in to my admin account in the server side, it happens because I'm changing the time of the server machine. 

but the time is really wrong. and I disabled NTP and the server has no access to the internet. 

these are my network configurations. 

peerdns = no 
ipaddr  = 192.168.1.1
netmask = 255.255.255.0
dns1 = 192.168.1.1
onboot = yes 

as you can see I've made the server also the dns1, (is this correct though ? i really don't know ) 

feel free to correct my network config 

And another problem is that I need to sync my freeipa server time to the right time zone? if thats the case then I do need internet connection for my Freeipa server , so that it could access ntp servers right?  ( or am I wrong? ) 

still this is a great breakthrough for my work 

Now what to do? 

ps. Martin attached is the krb5kdc.log after I changed the time of the server.  Httpd error log didnt changed at all after I tried to access the web UI and tried to log in.. 

TIA

Does:

$ id user at example.com

return you the user info?

if not and ipa-client-install was run successfully before, check 
nsswitch.conf if it has sssd configured (sss next to various providers).

if not run:
$ authconfig --enablesssd --update

if it doesn't help, try to run:
$ authconfig --disablesssd --update
$ authconfig --enablesssd --update

if it helps, please tell me. I'm curious if you suffer from one issue I 
experienced.
