Description Marco Guazzone 2011-06-11 20:32:56 UTC
SELinux is preventing /bin/bash from 'execute' accesses on the file /sbin/ldconfig.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that bash should be allowed execute access on the ldconfig 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 sh /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Dominick Grift 2011-06-11 20:43:27 UTC
Looks like not all fixes were back ported to f15., mgrepl could this be added as well?

Comment 2 Miroslav Grepl 2011-06-12 16:39:45 UTC
*** Bug 712622 has been marked as a duplicate of this bug. ***

Comment 3 Miroslav Grepl 2011-06-12 16:43:46 UTC
Yes, I will add it. 

Not sure how but I had to overlook a commit in flood of F16 fixes.

Marco,
you can allow it using 

# grep sh /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
