Description Matěj Cepl 2011-06-06 20:31:31 UTC
SELinux is preventing /usr/sbin/crond from 'entrypoint' accesses on the file /sbin/mkhomedir_helper.

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

If you believe that crond should be allowed entrypoint access on the mkhomedir_helper 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 crond /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Anything in /var/log/secure?

Comment 2 Tomas Mraz 2011-06-07 07:04:15 UTC
I suppose this is expectable if pam_mkhomedir is configured with authconfig. Although authconfig now prefers pam_oddjob_mkhomedir if it is installed on the system (oddjob-mkhomedir package).

Comment 4 Miroslav Grepl 2011-11-23 22:53:25 UTC
Matej,
does it still happen?

Oh boy. F15 ... that's soooooooo long time ago. I believe this one is gone. If not, then I'll open a new bug.

Comment 6 Miroslav Grepl 2011-11-24 09:24:59 UTC
OK, thx.
