Hi,

What's possible and what's practical could well be 2 different things. So yes you may get say XP to join, whether its stable, reliable, gives you the functionality you need and wont take a huge effort to look after is something else.

I realise there is the nirvana ideal that says get one "AD" to rule them all, but simply that isn't simple.

Sure IPA acts like an AD for Linux but pretty much Red Hat linux at that.  We will see other linux distros become as effortless and more "real" Unix happen as the eco-system develops, but managing windows and all its versions in a practical sense? cant see it.

So if you want to manage windows platforms at the lowest overall cost, lowest risk, minimal impact to your users and least effort buy a Win2k8R2 server licence and run it in a virtual environment, this is what I do at home and it will work well for say 5~100 users.   (NB we do it at work at well, just there is a huge difference between 5 users and 20000)

You then can sync the IPA and AD with winsync.  If that is too complex and you only want authentications then consider AD with something like Likewise Express which is free and connect your linux kit to AD, its limited but its simple/trivial.

Hi Dimitri,

Thanks for your response but I'm a little bit confused. Indeed, some users tell me that it's possible to join an IPA domain from a windows workstation and you say this is not possible.

I don't have an AD server, I want to configure IPA to act like an AD. My network contains Windows/Linux workstations and I want to centrally manage authentications.

Regards

If you setup trusts between IPA and AD then yes.
If not then you need to ssh from the system that belongs to the API domain.
IPA does not support Windows systems to be joined to IPA domain. But you can configure kerberos for Windows and use local Windows accounts. There are some HowTos on the wiki about it.
Alternatively you join Linux systems to AD and use it as your central authentication server then SSO would also work but you will loose ability to manage your Linux related policies.

Trusts is probably the best for you but there will be dragons.

For http restart you control that via sudo in IPA so its centrally managed, I have this working for one such server though I use the reload option instead.
to enable SSO with SSH from a ipa workstation, just edit /etc/ssh/sshd_config and make sure the line below is set to yes
"GSSAPIAuthentication yes"

If you've just made the change, it won't take effect until SSH is restarted. So do the usual service sshd restart.

I want to authenticate users on the server and controlling what can be done or not by them on the network. 10 other linux web servers should be accessible (console) by specific users and without the need to authenticating again (single sign on). On these web servers, users can issue specific commands like "/etc/init.d/httpd restart".
