Should be fine now. The whole thing originated from the fact that be_rootdn_bind() was passed a NULL SlapReply* without handling results accordingly.

Yes it is fixed, But in your fix, only the rootpw password works. If we have the rootdn also= as a dn stored inside the ldap tree then openldap does not tries to bind t= o the dn of the tree if the rootpw is incorrect if we use the same code segment of bind.cpp written for back-bdb which is: /* allow noauth binds */ switch ( be_rootdn_bind( op, NULL ) ) { case LDAP_SUCCESS: /* frontend will send result */ return rs->sr_err; default: break; } And the rootpw is not matched, then slapd will continue to search the ldap = tree and if it finds a dn and its userPassword matches, then it authenticat= es. If an appropriate dn / password is not found in the tree, then it throu= ghs the invalid credentials error. Maybe the bind-dbd way is more correct?

It's simply an issue with the entry cache not running its purge in some cases where it needs to. cn=monitor shows that the entry cache grows far beyond its configured size.

whether or not it could be related to some adverse interaction, e.g. with sssvlv, which has some paged-results specific code. Can you also post on overlays either global or specific to "olcDatabase={2}hdb"? p.

(ITS#6662) ldapsearch with slapd-ndb only works when filter is a substring
by gtzanetis＠pylones.gr 30 Sep '10

30 Sep '10

Full_Name: George Tzanetis Version: 2.4.23 stable OS: Red Hat Enterprise 5.5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (62.169.213.126) It seems that when using slapd-ndb the filters in ldapsearches only work if they are substrings. i.e *text or text* or te*xt for attributes that are not defined as indices. If the attribute is defined as an index then the substring filter does not work, as indicate in the manual. The slapd.conf is as follows: pidfile /usr/local/openldap/var/run/slapd.pid argsfile /usr/local/openldap/var/run/slapd.args ####################################################################### # NDB database definitions ####################################################################### #NDB database defintions database ndb suffix "dc=example,dc=gr" rootdn "cn=root,dc=example,dc=gr" rootpw secret dbconnect 192.168.6.11 dbhost 192.168.6.12 dbport 3306 dbname openldap dbuser ldapUser dbpass "1234" dbconnections 3 dbsocket /tmp/mysql.sock attrblob description index uid ####################################################################### # Monitor Database definitions ####################################################################### database monitor loglevel 5 The ldif of an ou: version: 1 dn: ou=test,dc=example,dc=gr objectClass: top objectClass: organizationalUnit ou: test dn: uid=user1,ou=test,dc=example,dc=gr objectClass: top objectClass: inetOrgPerson objectClass: posixAccount cn: user1 gidNumber: -1 givenName: user1 homeDirectory: * sn: user1 uid: user1 uidNumber: -1 userPassword:: 1234 dn: uid=user2,ou=test,dc=example,dc=gr objectClass: top objectClass: inetOrgPerson objectClass: posixAccount cn: user2 gidNumber: -1 givenName: user2 homeDirectory: * sn: user2 uid: user2 uidNumber: -1 userPassword:: 1234 dn: uid=user3,ou=test,dc=example,dc=gr objectClass: top objectClass: inetOrgPerson objectClass: posixAccount cn: user3 gidNumber: -1 givenName: user3 homeDirectory: * sn: user3 uid: user3 uidNumber: -1 userPassword:: 1234 dn: uid=user4,ou=test,dc=example,dc=gr objectClass: top objectClass: inetOrgPerson objectClass: posixAccount cn: user4 gidNumber: -1 givenName: user4 homeDirectory: * sn: user4 uid: user4 uidNumber: -1 userPassword:: 1234 the ldapsearch queries: -search with specific cn inside the ou: --------------------------------------------------------------------- ldapsearch -h 192.168.132.177 -b 'ou=test,dc=example,dc=gr' -D "cn=root,dc=example,dc=gr" -L -w 'secret' "cn=user1" version: 1 # # LDAPv3 # base <ou=test,dc=example,dc=gr> with scope subtree # filter: cn=user1 # requesting: ALL # # search result # numResponses: 1 --------------------------------------------------------------------- No result but if we search the cn as a substring: --------------------------------------------------------------------- ldapsearch -h 192.168.132.177 -b 'ou=test,dc=example,dc=gr' -D "cn=root,dc=example,dc=gr" -L -w 'secret1' "cn=user1*" version: 1 # # LDAPv3 # base <ou=test,dc=example,dc=gr> with scope subtree # filter: cn=user1* # requesting: ALL # # user1@test, test, example.gr dn: uid=user1@test,ou=test,dc=example,dc=gr objectClass: top objectClass: inetOrgPerson objectClass: posixAccount userPassword:: 1234 sn: user1 cn: user1 uid: user1@test givenName: user1 uidNumber: -1 gidNumber: -1 homeDirectory: * # search result # numResponses: 2 # numEntries: 1 --------------------------------------------------------------------- any substring will give a result i.e. cn=*user1, cn=user1*, cn=us*er1 etc. if we search for cn=user* it will display all entries of the ou as expected. The same behavior exists if we filter using any other attribute with the exception of the objectClass attribute, or with the uid attribute which is indexed. Is this normal? Thank you, George

I wanted to add that I do not find the contextCSN attribute anywhere inside= the database schema that the slapd-ndb backend creates. Maybe that is the reason I get the segmentation fault every time the slapd = process tries to update this attribute?

Hi, I built openldap using the new code. The rootpw now works, but if a wrong p= assword in an ldap query, then the ldap query process locks. e.g.: with rootdn: 'cn=3Droot,dc=3Dexample,dc=3Dgr' and rootpw: secret -when rootdn and rootpw are correct: ldapwhoami -h 192.168.6.10 -D 'cn=3Droot,dc=3Dexample,dc=3Dgr' -w 'secret' >dn:cn=3Droot,dc=3Dexample,dc=3Dgr -when rootdn is wrong: Ldapwhoami -h 192.168.6.10 -D 'cn=3Droot,dc=3Dexample,dc=3Dcom' -w 'secret' >ldap_bind: Invalid credentials (49) -when rootdn is correct and rootpw is wrong Ldapwhoami -h 192.168.6.10 -D 'cn=3Droot,dc=3Dexample,dc=3Dcom' -w 'secret1= ' "NO RESULT, the ldapwhoami locks" Here are the logs of the slapd process: ################################### #with correct rootdn & rootpw # ################################### daemon:

Can you post a configuration that shows the issue? Hi Pierangelo, My testing shows the issue is only really visible with large databases that return giant result sets. I don't expect you to see it with a small database and test003, because the amount of "lost" memory will be a few bytes at best.
