Hello,
I'm trying to define two sssd groups in order to assign a different login shell to AD users belonging to two different AD groups in our domain FOOBAR.GLOBAL. However, all users are unable to login and get an error "Authentication failed". If I change a sssd section to [domain/FOOBAR.GLOBAL] so to reflect the existing AD domain, users defined in that sssd group are able to login. However, clearly in this way I cannot define more than one section. Why is that? How to define sssd sections with names different than the existing AD domain?
Thanks in advance. Below is my sssd.conf.
[sssd] domains = FOOBAR_ADMINS.GLOBAL,FOOBAR_NOLOGIN.GLOBAL config_file_version = 2 services = nss, pam
[domain/FOOBAR_NOLOGIN.GLOBAL] ldap_user_search_filter = (memberOf=CN=Simple Users,OU=Security Groups,DC=FOOBAR,DC=GLOBAL) default_shell = /bin/sh ad_server = ad01.foobar.global ad_domain = FOOBAR.GLOBAL krb5_realm = FOOBAR.GLOBAL realmd_tags = manages-system joined-with-adcli cache_credentials = False id_provider = ad krb5_store_password_if_offline = True ldap_id_mapping = True use_fully_qualified_names = True fallback_homedir = /home/%u@%d access_provider = simple simple_allow_groups = Simple Users@FOOBAR.GLOBAL
[domain/FOOBAR_ADMINS.GLOBAL] ldap_user_search_filter = (memberOf=CN=Administrators,OU=Security Groups,DC=FOOBAR,DC=GLOBAL) default_shell = /bin/bash ad_server = ad01.foobar.global ad_domain = FOOBAR.GLOBAL krb5_realm = FOOBAR.GLOBAL realmd_tags = manages-system joined-with-adcli cache_credentials = False id_provider = ad krb5_store_password_if_offline = True ldap_id_mapping = True use_fully_qualified_names = True fallback_homedir = /home/%u@%d access_provider = simple simple_allow_groups = Administrators@FOOBAR.GLOBAL
If you're reading this via web, note that the @ sign got mutated to (a) in the simple_allow_groups configuration lines.

Are you able to at least resolve the users? What exact name are you using to resolve the users, username@foobar_nologin.global or username@foobar.global? The former would work, the latter would not.
btw if all you want is to munge the shell based on group memberships, maybe the sss_override tool would help?

An user belonging to the Simple Users group is resolved correctly via either one of these commands:
id simpleuser@FOOBAR_NOLOGIN.GLOBAL id simpleuser@FOOBAR.GLOBAL
Similarly, an user belonging to the Administrators group can be seen via either one of these commands:
id adminuser@FOOBAR_ADMINS.GLOBAL id adminuser@FOOBAR.GLOBAL
However, no user is able to log in. I've tried all these commands:
ssh simpleuser@FOOBAR_NOLOGIN.GLOBAL@<server> ssh simpleuser@FOOBAR.GLOBAL@<server> ssh adminuser@FOOBAR_ADMINS.GLOBAL@<server> ssh adminuser@FOOBAR.GLOBAL@<server>
Here's the ssh -vvv output after that <server> requests the password:
debug3: send packet: type 50 debug2: we sent a password packet, wait for reply Authentication failed.
SSSD logs would show this better, but I wonder if this is related to also using the AD domain name in the simple access filter. Do logins work if you use the name of the sssd section there instead of the AD domain name? Or, do the logins work if you comment out the access provider for a test?

Thanks a lot, it works. Changed
simple_allow_groups = Simple Users(a)FOOBAR.GLOBAL
to
simple_allow_groups = Simple Users(a)FOOBAR_NOLOGIN.GLOBAL
and it works as intended. One thing to keep in mind: These AD users must now be referenced in Linux (e.g. in /etc/sudoers) not by their AD domain of origin but by their sssd section domain, e.g simpleuser@FOOBAR_NOLOGIN.GLOBAL. For simplicity I also changed the other sssd section to [domain/FOOBAR.GLOBAL], and works fine.
Many thanks for your assistance.
