[SOLVED] DBMS_LDAP.delete_s result in error: ERR

DBMS_LDAP.delete_s result in error: ERR_268 Cannot find a partition for

I have problem in deleting any LDAP entry using DBMS_LDAP.delete_s function. My code looks like:

DECLARE
    l_ldap_user    VARCHAR2(256) := 'dc=example,dc=com';
    l_session      DBMS_LDAP.session;
    ...
BEGIN
    ...
    l_retval := dbms_ldap.delete_s(l_session, l_ldap_user || ',cn=Tink');
    ...
END
/

I use Apache Directory Studio version 2.0.0 to store LDAP data and it looks like:

dn: dc=example,dc=com
objectclass: top
objectclass: domain
dc: example
userPassword:: e1NTSEF9YTZIYUF0U1BGSnFOQ2piZm9ENStpV3BMQnJ1VnBlT21IbFAraHc9P
 Q==

dn: cn=Tink,dc=example,dc=com
objectClass: inetOrgPerson
objectClass: person
objectClass: organizationalPerson
objectClass: top
cn: Tink
sn: Tink
userPassword:: e1NTSEF9eDZBZUV2SzVEYmkrYlA2c0FCZU1zdk5YMzlUN1JUL3FOSk9KQmc9P
 Q==

As a result I receive following error message:

Error report -
ORA-31202: DBMS_LDAP: LDAP client/server error: No such object.

*Cause:    There is a problem either on the LDAP server or on the client.

Help me please because I run out of ideas how repair this code.

Solution

Problem was in the line:

l_retval := dbms_ldap.delete_s(l_session, l_ldap_user || ',cn=Tink');

Correct reading nodes in LDAP is: leaf.domainname.domainname

Answer for this problem:

l_retval := dbms_ldap.delete_s(l_session, 'cn=Tink,' || l_ldap_user); --l_ldap_user = 'dn=domain,dn=com'.
