I've been trying to get our new AD environment and our existing IPA
environment all happy, but am having little luck. To start, our info
and a few questions:
IPA servers running CentOS 6.5 and ipa-server-3.0.0-42
Windows DC servers running Windows Server 2012
Anonymized domain info:
IPA NetBIOS domain: IPA
IPA DNS domain: domain.com <http://domain.com>
WIN NetBIOS domain: AD
WIN DNS domain: win.domain.com <http://win.domain.com>
AD environment using itself for DNS, IPA environment using external
DNS (Cobbler/Bind). The appropriate _tcp, _ldap, etc. DNS entries have
been created in the domain.com <http://domain.com> domain in Bind. I
have set up users in IPA and AD with the same username and added a
name mapping in AD to usern...@domain.com <mailto:usern...@domain.com>.
How are the domains connected? Do you use trust or sync?
1) Is it possible to log into a workstation that's been joined to a
domain with IPA credentials?
You mean can I access a Windows workstation joined to AD domain by user
from IPA domain?
No it is not implemented. It will require Global Catalog support in IPA.
2) If so, what are the minimum requirements for that? Do I need to run
FreeIPA 3.3 on CentOS 7? FreeIPA 4 on Fedora? Something else?
3) Is there any way to log into the domain workstation with the
NetBIOS domain and username and have it authenticate against the IPA
environment? As in AD\username instead of usern...@domain.com
<mailto:usern...@domain.com>? If only the latter will work, will users
be able to map drives and access other AD resources without being
prompted for username/pass?
You seem to be looking for the full mutual trust capability. It is not
Help is welcome!
4) For initial setup of users, do the passwords for the AD and IPA
accounts need to be the same? Will a password change in the Windows
environment change the IPA password?
If you use sync then users and passwords are synced.
If you use trust, users stay where they are created (in AD or in IPA)
and client is redirected to the AD or IPA domain the user is created in.
Any other hints, etc. for how to get this all working would be
appreciated. I've gone through the FreeIPA AD Trust page(s) and
various other sources, but am unclear on how things should work and
whether or not I'm doing something wrong. Our old Windows 2003 domain
is authenticating fine against MIT Kerberos, so I'm rather surprised
how difficult this is proving to be.
If you just want to use IPA for windows you for now have to use the same
Kerberos setup on Windows workstations as you have in the old domain.
The main point if IPA is to server Linux clients not to replace AD. The
AD can be replaced with Samba 4 and we are working on making it support
trusts with IPA.
