Doc Type:	Bug Fix
Doc Text:	When a server-side control contains a matching rule, Directory Server fails to use the rule to index the values of the attributes. In this situation, the indexed keys are set to NULL. Previously, the server failed with a NULL pointer exception when comparing keys set to NULL. With this update, Directory Server verifies whether indexed values are NULL before comparing them. As a result, the server now returns an LDAP_OPERATION_ERROR message if it fails to index values.

Comment 6 Viktor Ashirov 2018-08-28 09:03:28 EDT

Build tested: 389-ds-base-1.3.7.5-26.el7_5.x86_64

Search with server side sort no longer crashes the server, but it doesn't return sorted results per matching rule (bz1615163):

[root@server ds]# ldapsearch -xLLL -D cn=Directory\ Manager -w Secret123 -b cn=users,cn=accounts,dc=ipa,dc=test -E sss=uid:2.5.13.3 "(uid=tuser*)" uid | grep uid:
uid: tuser2
uid: tuser3
uid: tuser
[root@server ds]# ldapsearch -xLLL -D cn=Directory\ Manager -w Secret123 -b cn=users,cn=accounts,dc=ipa,dc=test -E sss=-uid:2.5.13.3 "(uid=tuser*)" uid | grep uid:
uid: tuser2
uid: tuser3
uid: tuser


Marking as VERIFIED.
