When using the rwm, openldap down

[デージーネット 大野 公善 <ohno@designet.co.jp>]

Hi.

When I changed configuration for openldap, openldap stopped. (Aborted)
I was carried out the following operations.


(1) I created the following environment.
---- ---- ---- ----
# ldapsearch -LLL -Y EXTERNAL -b
'olcOverlay={0}rwm,olcDatabase={1}bdb,cn=config' -H ldapi:///
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
dn: olcOverlay={0}rwm,olcDatabase={1}bdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcRwmConfig
olcOverlay: {0}rwm
olcRwmRewrite: {0}rwm-rewriteEngine on
olcRwmRewrite: {1}rwm-rewriteContext searchFilter
olcRwmRewrite: {2}rwm-rewriteRule "aaa" "111" ":@"
olcRwmRewrite: {3}rwm-rewriteRule "bbb" "222" ":@"
---- ---- ---- ----

(2) I created the following ldif file.
---- ---- ---- ----
dn: olcOverlay={0}rwm,olcDatabase={1}bdb,cn=config
changetype: modify
delete: olcRwmRewrite
olcRwmRewrite: rwm-rewriteRule "aaa" "111" ":@"
-
---- ---- ---- ----

(3) I was carried out ldapmodify.
---- ---- ---- ----
# ldapmodify -Y EXTERNAL -H ldapi:/// -f down.ldif
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
modifying entry "olcOverlay={0}rwm,olcDatabase={1}bdb,cn=config"
ldap_result: Can't contact LDAP server (-1)
---- ---- ---- ----

In this case, openldap has stopped.

Is this openldap BUG?
