Thank you both very much for the fast responses!
The UPN suffixes were already correctly listed by ipa.
krb5_use_enterprise_principal = True
helped. In my scenario I additionally had to add
domain_resolution_order =
trusted-domain-a.com trusted-domain-b.com
and I got this finally working!
Thanks again, really appreciate it!
Best,
Florian

We are successfully running a FreeIPA setup connected to an AD using
kerberos to authenticate. (IPA is used as provider).
Our windows domain name is not identical to our main mail domain. For some users the User
logon name in windows (the one with @ not the old pre-win2000 one) is using a domain name
which has no kerberos servers etc. In windows authentication works perfectly, but in our
IPA setup we run into a big issue.
No matter which domain the user chooses to authenticate against our linux servers, the
linux server tries to authenticate against the kerberos servers of the domain which has no
servers.
In the krb5.conf we manually configured the kerberos servers of the windows AD for this
domain. Now we get [Realm not local to KDC] in the krb5_child.log.
Is there any way to forcefully replace the domain name when authenticating? We tried
using auth_to_local without success so far.
Hi,
please try to add
krb5_use_enterprise_principal = True
to the [domain/...] section in sssd.conf, restart SSSD and try again.
There is some logic implemented in SSSD to set the option to 'True'
automatically for 'id_provider = ipa' but it might fail. Currently we
cannot set it to 'True' by default because there might be some older IPA
server versions still around which cannot handle this option properly.
HTH
bye,
Sumit
