Jakub, thankyou for your reply.
Client OS is Ubuntu Xenial. Yes, I know... pats favourite labrador
goodbye. Sound of drawer opening and service revolver being loaded...
I did realise that the option p_auth_disable_tls_never_use_in_production =
true
the problem I have is that there is a CA cert on the Active Directory
controller. But I cannot see if there is an SSL certificate.
I may well be misunderstanding things.
Please don’t use this, not only it is very insecure, but also it
doesn’t
make any sense, this option is only useful if you use auth_provider=ldap.
With id_provider/auth_provider=ad, TLS is not used, but GSSAPI is.
Aha. Thankyou for that information.
I then have to ask the assembled choir (as I am not at the pearly gates) -
does AD in the default configuration have SSL certificate capability?
I have installed the Active Directory Certificate Services role

I find it easier to debug this kind of an issue with:
KRB5_TRACE=/dev/stderr ldapsearch -Y GSSAPI -H ldap://your.ad.dc -s base
-b “”
Also, what version and on what OS are you running?

This is expected, only the client$@realm principal is a user/computer
principal, the rest are service principals.

Because 9 is the highest?
