Doc Text: |
When the SELinux user content on an IdM server was set to an empty string, the SSSD SELinux evaluation utility previously returned an error. With this update, when an empty string is set, the SSSD correctly uses the default SELinux context value stored in the policy on the client, which prevents the described error from occurring.

I assume that in that case, the default comes from SSSD. Reassigning. Upstream ticket: https://fedorahosted.org/sssd/ticket/2587 The problem here is that SSSD does not delete the user's old selinux context. Jakub already wrote a patch and it is on review. As a workaround, you can use semanage tools to delete the old context: semanage login --delete username Then the right default will be picked up. * master: 01f78f755fde63997ccfded71fb8395569b11430 * sssd-1-12: 90efb3c2a48146d7b6cc81fe8422e9024144402a Verified in version [root@vm-idm-043 ~]# rpm -q sssd sssd-1.13.0-11.el7.x86_64 Master [root@vm-idm-014 ~]# ipa config-show | grep -i selinux SELinux user map order: guest_u:s0$xguest_u:s0$user_u:s0$staff_u:s0-s0:c0.c1023$unconfined_u:s0-s0:c0.c1023 Default SELinux user: unconfined_u:s0-s0:c0.c1023 [root@vm-idm-014 ~]# ipa config-mod --ipaselinuxusermapdefault= Maximum username length: 32 Home directory base: /home Default shell: /bin/sh Default users group: ipausers Default e-mail domain: stvidrange.test Search time limit: 2 Search size limit: 100 User search fields: uid,givenname,sn,telephonenumber,ou,title Group search fields: cn,description Enable migration mode: FALSE Certificate Subject base: O=STVIDRANGE.TEST Password Expiration Notification (days): 4 Password plugin features: AllowNThash SELinux user map order: guest_u:s0$xguest_u:s0$user_u:s0$staff_u:s0-s0:c0.c1023$unconfined_u:s0-s0:c0.c1023 Default PAC types: nfs:NONE, MS-PAC [root@vm-idm-014 ~]# ipa config-show | grep -i selinux SELinux user map order: guest_u:s0$xguest_u:s0$user_u:s0$staff_u:s0-s0:c0.c1023$unconfined_u:s0-s0:c0.c1023 [root@vm-idm-014 ~]# kdestroy -A [root@vm-idm-014 ~]# echo Secret123 | kinit aduser1 Password for aduser1: [root@vm-idm-014 ~]# ssh -l aduser1 `hostname` id -Z Could not chdir to home directory /home/adtest.qe/aduser1: No such file or directory unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 [root@vm-idm-014 ~]# service sssd stop ; rm -f /var/lib/sss/{mc,db}/* ; service sssd start Redirecting to /bin/systemctl stop sssd.service Redirecting to /bin/systemctl start sssd.service Client [root@vm-idm-043 ~]# kdestroy -A [root@vm-idm-043 ~]# echo Secret123 | kinit aduser1 Password for aduser1: [root@vm-idm-043 ~]# service sssd stop ; rm -f /var/lib/sss/{mc,db}/* ; service sssd start Redirecting to /bin/systemctl stop sssd.service Redirecting to /bin/systemctl start sssd.service [root@vm-idm-043 ~]# ssh -l aduser1 `hostname` id -Z unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 [root@vm-idm-043 ~]# rpm -q sssd sssd-1.13.0-11.el7.x86_64 [root@vm-idm-043 ~]# service sssd stop ; rm -f /var/lib/sss/{mc,db}/* ; service sssd start Redirecting to /bin/systemctl stop sssd.service Redirecting to /bin/systemctl start sssd.service [root@vm-idm-043 ~]# ssh -l aduser1 `hostname` id -Z unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
