Description of problem: I am trying to run ejabberd with PAM authentication, but SELinux shoots down PAM-related machinery during client authentication. I have the following in my /etc/ejabberd/ejabberd.conf: ---- >8 ---- {auth_method, pam}. {pam_service, "login"}. ---- 8< ---- SELinux is preventing /usr/sbin/unix_chkpwd from using the 'dac_override' capabilities. ***** Plugin dac_override (91.4 confidence) suggests *********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests *************************** If you believe that unix_chkpwd should have the dac_override capability 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: # grep unix_chkpwd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:rabbitmq_beam_t:s0 Target Context system_u:system_r:rabbitmq_beam_t:s0 Target Objects [ capability ] Source unix_chkpwd Source Path /usr/sbin/unix_chkpwd Port <Unknown> Host (removed) Source RPM Packages pam-1.1.6-12.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-69.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.5-301.fc19.x86_64 #1 SMP Tue Jun 11 19:39:38 UTC 2013 x86_64 x86_64 Alert Count 4 First Seen 2013-08-05 13:26:24 MSK Last Seen 2013-08-05 13:26:31 MSK Local ID 2b38c612-c47a-45af-b90a-58a35452340a Raw Audit Messages type=AVC msg=audit(1375694791.125:2106): avc: denied { dac_override } for pid=16560 comm="unix_chkpwd" capability=1 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:system_r:rabbitmq_beam_t:s0 tclass=capability type=AVC msg=audit(1375694791.125:2106): avc: denied { dac_read_search } for pid=16560 comm="unix_chkpwd" capability=2 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:system_r:rabbitmq_beam_t:s0 tclass=capability type=SYSCALL msg=audit(1375694791.125:2106): arch=x86_64 syscall=open success=no exit=EACCES a0=7ff87b5a243b a1=80000 a2=1b6 a3=0 items=0 ppid=16249 pid=16560 auid=4294967295 uid=0 gid=989 euid=0 suid=0 fsuid=0 egid=989 sgid=989 fsgid=989 ses=4294967295 tty=(none) comm=unix_chkpwd exe=/usr/sbin/unix_chkpwd subj=system_u:system_r:rabbitmq_beam_t:s0 key=(null) Hash: unix_chkpwd,rabbitmq_beam_t,rabbitmq_beam_t,capability,dac_override Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.9.5-301.fc19.x86_64 type: libreport
