I've tried following this guide to set up realmd and sssd with active directory: http://funwithlinux.net/2014/04/join-ubuntu-14-04-to-active-directory-domain-using-realmd/
When I run the command realm –verbose join domain.company.com –user-principal=c-u14-dev1/
[email protected] –unattended everything seems to connect. My sssd.conf looks like the following:
[nss]
filter_groups = root
filter_users = root
reconnection_retries = 3
[pam]
reconnection_retries = 3
[sssd]
domains = DOMAIN.COMPANY.COM
config_file_version = 2
services = nss, pam
[domain/DOMAIN.COMPANY.COM]
ad_domain = DOMAIN.COMPANY.COM
krb5_realm = DOMAIN.COMPANY.COM
realmd_tags = manages-system joined-with-adcli
cache_credentials = True
id_provider = ad
krb5_store_password_if_offline = True
default_shell = /bin/bash
ldap_id_mapping = True
use_fully_qualified_names = True
fallback_homedir = /home/%d/%u
access_provider = ad
My /etc/pam.d/common-auth looks like this:
auth [success=3 default=ignore] pam_krb5.so minimum_uid=1000
auth [success=2 default=ignore] pam_unix.so nullok_secure try_first_pass
auth [success=1 default=ignore] pam_sss.so use_first_pass
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth required pam_permit.so
# and here are more per-package modules (the "Additional" block)
auth optional pam_cap.so
However, when I try to SSH into the machine with my active directory user, I see the following in auth.log:
Aug 21 10:35:59 c-u14-dev1 sshd[11285]:
Invalid user nwalke from myip
Aug 21 10:35:59 c-u14-dev1 sshd[11285]: input_userauth_request:

Aug 21 10:36:12 c-u14-dev1 sshd[11285]: Failed password for
invalid user nwalke from myip port 34455 ssh2
What do I need to do to allow active directory users the ability to log in?
