that's intersting. "performing access check" is really missing.
also the "sdap_access" lines are not there. Therefore i do have:
(Tue May 12 13:16:20 2015) [sssd[be[default]]] [dp_get_options]
(0x0400): Option ldap_access_filter has no value
(Tue May 12 13:16:20 2015) [sssd[be[default]]] [dp_get_options]
(0x0400): Option ldap_access_order has value host
(Tue May 12 13:16:20 2015) [sssd[be[default]]] [be_process_init]
(0x2000): ACCESS backend target successfully loaded from provider [ldap].
"Requesting attrs: [objectClass]" and "Requesting attrs: [host]" are in
the logfile.
So there is no access check apart from username and password check -
otherwise i would not have been able to login.
The question is why doesn't it perform these checks.
Just to repete: My sssd.conf contains
access_provider = ldap
ldap_access_order = host
ldap_user_authorized_host = host
I read something about "pam_check_host_attr" in /etc/ldap.conf But this
does not help in my /etc/openldap/ldap.conf (already tested).
Any idea is still welcome.
With kind regards, ulrich
