Hello Howard,
This means I need to patch the openldap instance or a default ordering rule= can be set for that attribute on the fly? Thanks again for your help and a= ssistance.
BR,
Maria

It seems that openldap as of 2.4.31 is not RFC complaint (https://www.ietf.org/rfc/rfc2891.txt) due to failure in response when or=
dering
match rule is empty while doing server side sorting. Example below:
False. OpenLDAP is completely correct and RFC-compliant in its behavior.
empty ordering rule:
ldapsearch -E sss=3Dcn '(cn=3Dccc*)' cn' (&(objectClass=3DinetOrgPerson)(=
cn=3Dccc*))' -H
ldap://IP:389 -b "ou=3DUsers,dc=3Dopenstack,dc=3Dorg" -D "cn=3Daaa1, ou=3DUsers,dc=3Dopenstack,dc=3Dorg" -x -W # extended LDIF # # LDAPv3 # base <ou=3DUsers,dc=3Dopenstack,dc=3Dorg> with scope subtree # filter: (cn=3Dccc*) # requesting: cn (&(objectClass=3DinetOrgPerson)(cn=3Dccc*)) # with server side sorting control #
# search result search: 2 result: 18 Inappropriate matching text: serverSort control: No ordering rule
This result is correct since the cn attribute has no ordering rule defined = in the schema.
# numResponses: 1
caseIgnoreOrderingMatch ordering rule:
ldapsearch -E sss=3Dcn:caseIgnoreOrderingMatch '(cn=3Dccc*)' cn' (&(objectClass=3DinetOrgPerson)(cn=3Dccc*))' -H ldap://IP:389 -b "ou=3DUsers,dc=3Dopenstack,dc=3Dorg" -D "c3D3Daaa1, ou=3DUsers,dc=3Dopens=
tack,dc=3Dorg" -x
-W # extended LDIF # # LDAPv3 # base <ou=3DUsers,dc=3Dopenstack,dc=3Dorg> with scope subtree # filter: (cn=3Dccc*) # requesting: cn (&(objectClass=3DinetOrgPerson)(cn=3Dccc*)) # with server side sorting control #
# ccc0, Users, openstack.org dn: cn=3Dccc0,ou=3DUsers,dc=3Dopenstack,dc=3Dorg # search result search: 2 result: 0 Success control: 1.2.840.113556.1.4.474 false MAMKAQA=3D sortResult: (0) Success
however the RFC states that the orderingRule is OPTIONAL as below:
SortKeyList ::=3D SEQUENCE OF SEQUENCE { attributeType AttributeDescription, orderingRule [0] MatchingRuleId OPTIONAL, reverseOrder [1] BOOLEAN DEFAULT FALSE }however openldap fails to return entries.
The rule is optional in the control itself, but a valid ordering rule must exist somewhere. Since the attribute schema doesn't define one then you mus= t provide one yourself.
Closing this ITS.
