Description Wes Morgan 2009-01-30 22:11:35 UTC 
Description of problem: slapd init script assumes /tmp (or $TMP) is executable, but setting noexec on a /tmp partition is a common (and recommended) security practice. It creates a wrapper script in that directory and then tries to execute it, which will fail with a cryptic permission denied error from bash.


Version-Release number of selected component (if applicable): 2.3.43-3.el5


How reproducible: Every time.


Steps to Reproduce:
1. Mount /tmp as a separate partition
2. Set the noexec option on it in fstab
3. Install openldap-servers package
4. Try to start with /sbin/service ldap start
  
Actual results:
permission denied error from bash (mentions the generated wrapper filename, e.g. /tmp/start-slapd.654321)


Expected results:
slapd starts

Additional info:
This wrapper should be created somewhere that is more often consider safe for executables. Maybe /var/run/openldap. It looks like it's created to work around some issues w/ the daemon command, so maybe it could be fixed there too.
Comment 1 Jan Safranek 2009-03-10 12:26:25 UTC 
This was fixed in Fedora some time ago and should be backported to RHEL.
Comment 5 Jan Zeleny 2009-11-16 09:49:31 UTC
