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 'read' accesses on the file /etc/shadow. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that unix_chkpwd should be allowed read access on the shadow 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: # 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:object_r:shadow_t:s0 Target Objects /etc/shadow [ file ] 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 setup-2.8.71-1.fc19.noarch 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 2 First Seen 2013-08-05 13:28:14 MSK Last Seen 2013-08-05 13:28:14 MSK Local ID 1c1f1163-2f24-4c22-8798-c05c0d7faa70 Raw Audit Messages type=AVC msg=audit(1375694894.607:2114): avc: denied { read } for pid=16674 comm="unix_chkpwd" name="shadow" dev="dm-3" ino=395927 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:object_r:shadow_t:s0 tclass=file type=SYSCALL msg=audit(1375694894.607:2114): arch=x86_64 syscall=open success=no exit=EACCES a0=7f76d525c43b a1=80000 a2=1b6 a3=0 items=0 ppid=16249 pid=16674 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,shadow_t,file,read Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.9.5-301.fc19.x86_64 type: libreport
