Hello, still having issues with ovirt SSO and Debian OS. Other OSes (Windows/Fedora 24) works just fine. Some information: OS: Debian 8.5 (jessie) I've followed manual on https://www.ovirt.org/documentation/how-to/gues t-agent/install-the-guest-agent-in-debian/ and installed ovirt-agent. I can get info via spice socket on hypervisor side, this means that agent works fine. I've compiled pam-ovirt-cred and copied it into /lib/x86_64-linux- gnu/security/ I've configured /etc/pamd/gdm-ovirtcred (just copied from working Fedora 24) But still login fails. I can see this in ovirt-agent log file: Dummy-2::INFO::2016-07-28 12:49:51,046::OVirtAgentLogic::270::root::Received an external command: login... Dummy-2::DEBUG::2016-07-28 12:49:51,047::OVirtAgentLogic::304::root::User log-in (credentials = '\x00\x00\x00\x04test********\x00') Dummy-2::INFO::2016-07-28 12:49:51,047::CredServer::207::root::The following users are allowed to connect: [0] Dummy-2::DEBUG::2016-07-28 12:49:51,047::CredServer::272::root::Token: 760258 Dummy-2::INFO::2016-07-28 12:49:51,047::CredServer::273::root::Opening credentials channel... Dummy-2::INFO::2016-07-28 12:49:51,047::CredServer::132::root::Emitting user authenticated signal (760258). Dummy-2::INFO::2016-07-28 12:49:51,178::CredServer::277::root::Credentials channel was closed. This looks okay. The error is on pam side (auth.log): Jul 28 12:49:39 desktop64 gdm-ovirtcred]: pam_succeed_if(gdm- ovirtcred:auth): error retrieving user name: Conversation error Jul 28 12:49:39 desktop64 gdm-ovirtcred]: pam_ovirt_cred(gdm- ovirtcred:auth): Failed to acquire user's credentials Have no idea, where it fails. Would appreciate, if you could help me here a bit. Thank you.
