[Freeipa-users] AD trust users cannot login to Solaris

[Nathan Peters]

I am using FreeIPA 4.1.2 on CentOS 7.

Yes, AD users can login to all Linux / Centos machines.

Also, when I'm at a shell prompt on the FreeIPA DC, I can getent passwd 
<aduser> and I see their info properly.

The guide you linked below is the first thing I read while trying to 
troubleshoot this.  It seems aimed toward older sssd clients < 1.9 and not 
Solaris clients.

I will try this again tomorrow and confirm that the request is being passed 
to the FreeIPA DC and rejected there.  I was assuming that it was being 
rejected by the Solaris machine.

What version of IPA are you using?
Have you verified that trust actually works by looking up or
authenticating with the AD users on the SSSD client or on the server itself?

The compat tree fills the data dynamically as you need it. When an AD
user accesses Solaris box Solaris would authenticate against the compat
tree. Compat tree will use SSSD on the server to authenticate against
the AD. It seems that this part is failing. SSSD logs from the IPA
server with high debug level would be helpful.
