Description Aleksandar Milivojevic 2005-08-18 10:25:32 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050721 CentOS/1.0.6-1.4.1.centos4 Firefox/1.0.6

Description of problem:
I've configured squid to check passwords using SASL like this:

# grep 'sasl_auth' /etc/squid/squid.conf
auth_param basic program /usr/lib/squid/sasl_auth

# cat /usr/lib/sasl2/squid_sasl_auth.conf
pwcheck_method: saslauthd

However, SELinux is blocking Squid's sasl_auth module from connecting to saslauthd's socket:

Aug 17 15:51:09 t112 kernel: audit(1124311869.679:0): avc:  denied  { write } for  pid=6417 comm=sasl_auth name=mux dev=dm-3 ino=180280 scontext=root:system_r:squid_t tcontext=root:object_r:var_run_t tclass=sock_file

Version-Release number of selected component (if applicable):
selinux-policy-targeted-1.17.30-2.88

How reproducible:
Always

Steps to Reproduce:
1. configure squid and sasl_auth as described above
  

Additional info:

Comment 1 Aleksandar Milivojevic 2005-08-18 10:38:28 EDT

Just a small note.  sasl_auth is not a "loadable module".  It is stand-alone
helper application (runs as separate process, started by Squid).  So it is
sufficient for sasl_auth process to have access to saslauthd's socket.  Squid
itself does not need access to it.

Fixed in U2.
