Description of problem: Happened in normal system use after the 'map' permission was introduced. SELinux is preventing gdm-session-wor from 'map' accesses on the file /var/lib/sss/mc/passwd. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that gdm-session-wor should be allowed map access on the passwd file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'gdm-session-wor' --raw | audit2allow -M my-gdmsessionwor # semodule -X 300 -i my-gdmsessionwor.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:sssd_public_t:s0 Target Objects /var/lib/sss/mc/passwd [ file ] Source gdm-session-wor Source Path gdm-session-wor Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages sssd-common-1.15.3-2.fc27.x86_64 Policy RPM selinux-policy-3.13.1-270.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.13.0-0.rc4.git4.1.fc27.x86_64 #1 SMP Fri Aug 11 15:03:46 UTC 2017 x86_64 x86_64 Alert Count 27 First Seen 2017-08-12 17:35:42 PDT Last Seen 2017-08-14 21:51:53 PDT Local ID be93f57a-7b81-4d10-989c-fb3f2da68ae7 Raw Audit Messages type=AVC msg=audit(1502772713.494:687): avc: denied { map } for pid=15521 comm="gdm-session-wor" path="/var/lib/sss/mc/passwd" dev="dm-2" ino=393238 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:sssd_public_t:s0 tclass=file permissive=1 Hash: gdm-session-wor,xdm_t,sssd_public_t,file,map Version-Release number of selected component: selinux-policy-3.13.1-270.fc27.noarch Additional info: component: selinux-policy reporter: libreport-2.9.1 hashmarkername: setroubleshoot kernel: 4.13.0-0.rc4.git4.1.fc27.x86_64 type: libreport
