Hello --
We are running the 14.04.3 LTS 64-bit release as a virtual machine on a Vmware appliance. The goal of the installation is to create a Samba server that utilizes Active Directory authentication. To that end I utilized the following procedure:
http://www.kiloroot.com/add-ubuntu-1...n-credentials/http://www.kiloroot.com/add-ubuntu-14-04-server-or-desktop-to-microsoft-active-directory-domain-login-to-unity-with-domain-credentials/
Afterwards, I referenced the following documentation to confirm that all configuration files had the appropriate entries:
https://help.ubuntu.com/lts/serverguide/sssd-ad.html
The problem is the following: I am unable to log into the server from the console or via SSH using my Active Directory user account. The syntax that I use when doing an SSH connection is the following:
ssh -v -l <username>@<domainname> <fully qualified domain name>
The output that was generated is the following:
OpenSSH_6.0p1 Debian-4, OpenSSL 1.0.1e 11 Feb 2013 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to <fully qualified domain name> [<ip address>] port 22. debug1: Connection established. debug1: identity file /home/knoppix/.ssh/id_rsa type -1 debug1: identity file /home/knoppix/.ssh/id_rsa-cert type -1 debug1: identity file /home/knoppix/.ssh/id_dsa type -1 debug1: identity file /home/knoppix/.ssh/id_dsa-cert type -1 debug1: identity file /home/knoppix/.ssh/id_ecdsa type -1 debug1: identity file /home/knoppix/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.7 debug1: match: OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.7 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.0p1 Debian-4 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA ec:09:c1:bc:d0:11:f3:8c:45:3f:dd:3a:96:ba:2a:17 debug1: Host '<fully qualified domain name>' is known and matches the ECDSA host key. debug1: Found key in /home/knoppix/.ssh/known_hosts:29 debug1: ssh_ecdsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Trying private key: /home/knoppix/.ssh/id_rsa debug1: Trying private key: /home/knoppix/.ssh/id_dsa debug1: Trying private key: /home/knoppix/.ssh/id_ecdsa debug1: Next authentication method: password <username>@<domainname>@<fully qualified domain name>'s password: Connection closed by <ip address>
I checked the auth.log file, and the following entries were present:

Does anyone have thoughts on this?
Thanks.
