slapd segfaults when a bind fails due to an incorrect password if the glue
overlay is in use....

I can replicate this by running slapd and attempting to bind (using ldapsearch)
as a real user [not rootdn] with an incorrect password.

Output from gdb follows...

(gdb) run -u ldap -g ldap -h "ldap:// ldaps://" -d0
Starting program: /usr/share/src/openldap-2.3.0alpha/servers/slapd/slapd -u ldap
-g ldap -h "ldap:// ldaps://" -d0
