FYI the problem was discovered & fixed a while ago but I did not sent reply to 
you. It was fixed in all maintained branches (v2+) of bind-dyndb-ldap.

All supported versions of Fedora were patched so it should not happen again.

You can watch RHEL status on:

RHEL 6.y:

RHEL 7.y:

Have a nice day!
