[Spacewalk-list] Spacewalk and AD/SSSD Based User Authentication

Mon Mar 12 18:58:04 UTC 2018

Try to go trough the SW/FreeIPA documentation (https://github.com/spacewalkproject/spacewalk/wiki/SpacewalkAndIPA) 
DON'T COPY PASTE, read, understand and skip the parts of ipa installation and config as you already have sssd up and running so that should be sufficient. 
Take a backup before you mess around with you SW deployment so I won't feel bad about the tips! 

As far as the channel related stuff, after you have the external auth working for rhn admins, you should be able to map another group for dev's with specific permissions (subscribe/unsubscribe systems to software channels) 

That's at least how the theory would be, personally I would prefer to add all development required software channels to the whole development env/machines, and they can install whatever they want from that channels. 
It will save you the hassle of educating users on how to use spacewalk or other time consuming questions.

SW 2.7 on RHEL 7.4 

The HTTPD conf files are either commented out, or in the case of auth_kerb.conf, empty. This is a completely out of the box setup and the only documentation I’ve been able to find on this on RH’s portal mentions just the config changes I made. Nothing to do with the files you mentioned. 

Is there a better how-to to describe the full changes that need to take place to enable this? 

As far as role map, I only want end users to be able to subscribe to additional software channels that we don’t push by default. For example, we don’t have Microsoft’s channel in our base activation key, but would like to give our developers an opportunity to install software from it without admin intervention. 

It appears that doing spacewalk-channel –add –c microsoft_rhel7 prompts for a username and password so they are unable to add the channel.

Spacewalk version and OS please... 

Also log entries except the tomcat would be helpful. 

What's the content of following: 
/etc/httpd/conf.d/intercept_form_submit.conf 

/etc/httpd/conf.d/ authnz_pam.conf 

/etc/httpd/conf.d/ auth_kerb.conf 

I don't think that you need to create the user if you do role map for external authenticated users ( Admin -> Users -> External Authentication -> Group Role Mapping )

Hi! 

I’m looking to potentially use SSSD and Active Directory to authenticate our users to Spacewalk. The Spacewalk server is already on the domain and we authenticate just fine via SSH using AD. 

I added the following to the rhn.conf file: 

pam_auth_service = spacewalk-satellite 

Created the spacewalk-satellite pam.d file: 

#%PAM-1.0 

auth required pam_env.so 

auth sufficient pam_sss.so no_user_check 

auth required pam_deny.so 

account required pam_sss.so no_user_check 

Restarted spacewalk. Created a user mdiorio in the GUI and checked the box to use PAM. 

But get the following error when I go to log in. 

Mar 12 11:51:21 la-1pspacewalk server: 2018-03-12 11:51:21,304 [ajp-bio-0:0:0:0:0:0:0:1-8009-exec-4] WARN com.redhat.rhn.domain.user.legacy.UserImpl - PAM login for user User mdiorio (id 2, org_id 1) failed with error Permission denied. 

Mar 12 11:51:23 la-1pspacewalk server: 2018-03-12 11:51:23,304 [ajp-bio-0:0:0:0:0:0:0:1-8009-exec-4] INFO com.redhat.rhn.frontend.action.LoginAction - LOCAL AUTH FAILURE: [mdiorio] 

I can kinit my account on the server without a problem. 

Not sure what I’m missing. Thanks!
