I'm running Fedora 26 sssd --version 1.15.3
I am authentication against an Active Directory Domain that has posix extensions enabled. All my ubuntu and centos machines are using power broker or winbind to authenticate to the domain. I want to transition away from power broker. I tried using winbind to connect fedora but I end up with issues of it not using posix extensions from my active directory. So I tried sssd out and see that users show correctly when I run the command getent passwd <username> when using winbind I had to use template for the shell and home directories which I did not like. This is not happening on my ubuntu or centos servers with the same config. There config if it helps is as follows
[global] security = ads realm = MIND.UNM.EDU workgroup = MIND idmap config * : backend = tdb idmap config * : range = 2000-7999 idmap config MIND:backend = ad idmap config MIND:schema_mode = rfc2307 idmap config MIND:range = 8000-9999999 winbind nss info = rfc2307 winbind use default domain = yes # so that the users show up in getent winbind enum users = yes # so that the groups show up in getent winbind enum groups = yes restrict anonymous = 2 #added the following 2 for the Badlock updates that change the defaults #to no longer work with my domain controllers ldap server require strong auth = no client ldap sasl wrapping = plain
Since that wasn't working, I uninstalled winbind and reinstalled sssd (I had removed it while testing samba since I know they can interfere.)
I used realm to leave and rejoin the domain
It looks like realm rewrote my smb.conf file as such
[global] security = user idmap config * : backend = tdb idmap config * : range = 2000-7999 idmap config MIND:backend = ad idmap config MIND:schema_mode = rfc2307 idmap config MIND:range = 8000-9999999 winbind nss info = rfc2307 winbind use default domain = yes # so that the users show up in getent winbind enum users = yes # so that the groups show up in getent winbind enum groups = yes restrict anonymous = 2 #added the following 2 for the Badlock updates that change the defaults #to no longer work with my domain controllers ldap server require strong auth = no client ldap sasl wrapping = plain template homedir=/na/homes/%U template shell=/bin/bash
My sssd.conf file looks like so
[sssd] domains = mind.unm.edu config_file_version = 2 services = nss, pam
[domain/mind.unm.edu] ad_domain = mind.unm.edu krb5_realm = MIND.UNM.EDU 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 ldap_id_mapping = False #use_fully_qualified_names = True use_fully_qualified_names = False fallback_homedir = /home/%u@%d access_provider = ad # debug = 3
I learned with ldap_id_mapping = True I was getting funny uid's and that interfered with my isilon that is using rfc2307 to our domain. And I want to login with <username> not <domain>\<username> so i set use_fully_qualified_names = False
While reading this https://docs.pagure.org/SSSD.sssd/users/troubleshooting.html
under sections: Common AD provider issues->A group my user is a member of doesn’t display in the id output
In case the group is not present in the id -G output at all, there is something up with the initgroups part.
This is the case but I'm not really sure where to go from here.
I set debug on the domain to 3 and my /var/log/sssd/sssd_<domainname> looks as follows when I run id -G <user> in this case the user is jsadowski
id -G <username> is only showing the primary group for any user I have tried. ...
