Hi Johan,

I'm using Ubuntu with FreeIPA. I'm not using the ldapd as I've found it 
unreliable. I'm using the libnss-ldap and manually configured kerberos. 
ldapd does not support nested groups last I checked, that's a downside 
too. It's not perfect, sssd would have been better, but it works just fine.

If you lower the bind_timelimit and timelimit quite low (a few seconds) 
it's not too bad when a ipa server is unavailable. nscd is required to 
overcome some issues with the libnss-ldap. (Such as Thunderbird 
segfaulting...)

I've used cfengine to make an IPA config script for clients not 
supporting sssd and ipa-client-install. I'm sure you could do the same 
with puppet.

To get group based login, I've used the AllowGroups property in sshd.

Hope this makes sense. :)

Regards,
Siggi
