(ITS#5284) cn=config overlay order
by dhawes＠vt.edu 14 Dec '07

14 Dec '07

Full_Name: David Hawes Version: 2.3.39/2.4.6 OS: Debian GNU/Linux URL: Submission from: (NULL) (96.228.44.90) Overlays are processed in the reverse order of slapd.conf when using slapd.d. If I have the following in slapd.conf: ... overlay overlay1 overlay overlay2 overlay overlay3 ... and convert it to slapd.d, I will see the following in cn=config: ... # {0}overlay3, {1}bdb, config dn: olcOverlay={0}overlay3,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig olcOverlay: {0}overlay3 # {1}overlay2, {1}bdb, config dn: olcOverlay={1}overlay2,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig olcOverlay: {1}overlay2 # {2}overlay1, {1}bdb, config dn: olcOverlay={2}overlay1,olcDatabase={1}bdb,cn=config objectClass: olcOverlayConfig olcOverlay: {2}overlay1 ... When slapd is started with slapd.conf, the overlay stack is correct (overlay3 -> overlay2 -> overlay1 for processing order), although cn=config reports the above. When slapd.d is used, the overlay stack is the opposite (overlay1 -> overlay2 -> overlay3). This occurs in both 2.3.39 and 2.4.6. I see this as a problem in situations where order of overlays is important (syncprov comes to mind).

(ITS#5280) JLDAP waits for response for request which hasn't been sent because of connection shutdown

Full_Name: Marcin Waldowski Version: novell-jldap-devel-2007.10.12-1netware_windows OS: Windows XP URL: Submission from: (NULL) (83.20.102.205) Hello. Our application gets lots of information from LDAP server which uses refferals. Code which use jldap is executed in single thread. After some time of obtaining informations JLDAP hangs in MessageAgent.getLDAPMessage() as you can see at following thread dump: http://rafb.net/p/kwhTyh67.html It is repeatable every time we execute our application. It hangs always in the same line of JLDAP code. We turned on jldap debug (-Dldap.debug=TraceAll) and also sniffed communication between JLDAP and LDAP server using Wireshark. Interesting part of JLDAP debug you can see here: http://rafb.net/p/diqKzz11.html As you can see some refferal connections is lost in lines 14, 35, 53. After that we have some writes to that connections in lines 240 (message 146), 283 (message 147) and 333 (message 148). All this writes didn't come to the wire (as we can see in Wireshark or rather cannot see) because of "java.io.IOException: Output stream not initialized". This exception is only logged to debug stream and silently discarded in com.novell.ldap.Connection.writeMessage(LDAPMessage msg) because variable clientActive is false. So, If I understand it correctly, caller code doesn't know that anything goes wrong in called (write message) code. As a result JLDAP still wait for responses of messages 146, 147, 148 which hasn't been sent. This ends up with forever wait in line 368 of debug stream. Regards Marcin

And in some cases such a Google search gives a better interface than a browser search, since it can show all resulsts together, with some context. The HTML seems easy enough - I derived this from a "search within results" form in a Google search: <form action="http://www.google.com/search"> <input type=hidden name=q value="site:openldap.org/doc/admin24"> <input type=text name=as_q size=31 maxlength=256 value=""> <input type=submit name=btnG VALUE="Search Admin Guide"> </form> I don't know how easy it is to auto-insert it in the Guide though.

(ITS#5277) Feature request: Impose SSL/TLS for some addresses/interfaces
by michele.codutti＠uniud.it 13 Dec '07

13 Dec '07

Full_Name: Michele Codutti Version: 2.3 OS: Linux/Debian URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (158.110.7.132) Recently I need to implement a clustered system of OpenLDAP with syncrepl replication method. Every node has two interfaces: one public (let's say eth0) and one connected to a private subnet (let's say eth1). What I want is to impose only SSL/TLS connection on eth0 and unencrypted connection on eth1. I want this because is useless to encrypt syncrepl traffic through the private (dedicated and secured) subnet. I haven't found any directive that do what I want. At last I've implemented a solution suggested by Pierangelo Masaratti. I imposed TLS/SSL by these ACL's: access to * by sockurl="ldap://$PUBLIC_NAME" ssf=128 break by sockurl="ldap://$PUBLIC_NAME" stop by sockurl="ldaps://$PUBLIC_NAME" ssf=128 break by sockurl="ldaps://$PUBLIC_NAME" stop by * break Pierangelo also suggested me to write an ITS to ask for a specific directive to do this more naturaly. So here I'm. Could it be done?

After chatting with Kurt, we confirmed that there was no reason to drop the alias from our schema files, so I've restored it.

For example with this slapd.conf, we get: #ucdata-path "/opt/zimbra/openldap/ucdata" include "/opt/zimbra/openldap/etc/openldap/schema/core.schema" include "/opt/zimbra/openldap/etc/openldap/schema/cosine.schema" include "/opt/zimbra/openldap/etc/openldap/schema/inetorgperson.schema" include "/opt/zimbra/openldap/etc/openldap/schema/amavisd.schema" include "/opt/zimbra/openldap/etc/openldap/schema/zimbra.schema" include "/opt/zimbra/lib/conf/zimbra-ext.schema" threads 8 pidfile "/opt/zimbra/openldap/var/run/slapd.pid" argsfile "/opt/zimbra/openldap/var/run/slapd.args" TLSCertificateFile /opt/zimbra/conf/slapd.crt TLSCertificateKeyFile /opt/zimbra/conf/slapd.key TLSVerifyClient never loglevel 32768 # Load dynamic backend modules: modulepath /opt/zimbra/openldap/libexec/openldap moduleload back_bdb.la moduleload back_monitor.la moduleload syncprov.la moduleload accesslog.la <acl lines snipped> database config rootpw {SSHA}+wKEnqbcbxssdGDKx1LeNsoL90Ha2Lzx database monitor rootdn "cn=config" access to dn.children="cn=monitor" by dn.children="cn=admins,cn=zimbra" read include /opt/zimbra/conf/bdb-conf include /opt/zimbra/conf/syncrepl-conf bdb-conf is: database bdb suffix "" rootdn "cn=config" cachesize 10000 idlcachesize 10000 checkpoint 64 5 directory "/opt/zimbra/openldap-data" index objectClass eq sizelimit unlimited timelimit unlimited And we can see it is clearly processed, so why is the syncrepl line getting tagged to the monitor backend? line 47 (index entryCSN eq) index entryCSN 0x0004 line 48 (sizelimit unlimited) line 49 (timelimit unlimited) line 154 (include /opt/zimbra/conf/syncrepl-conf) reading config file /opt/zimbra/conf/syncrepl-conf line 13 (syncrepl ***) /opt/zimbra/conf/syncrepl-conf: line 13: database monitor does not support operations required for syncrepl /opt/zimbra/conf/slapd.conf: line 154: <include> handler exited with 1!

(ITS#5275) Poor LDAP performance when we reach 1000 connections

Full_Name: Chris Hodson Version: 2.3.32 OS: Red Hat EL 4 Rel 4 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (198.207.0.5) We're using a Red Hat EL 4 release 4 box to run openLDAP version 2.3.32. Every night we find ourselves reaching 1000+ (netstat | grep ldap | wc -l) connections to our LDAP server and have found the only resolution to restart the LDAP service daily. When we get to 1000+ connections performance takes a huge hit and no one is able to login to any box utilizing LDAP. This server consists of 2 dual core Opeterons with 8 GBs of memory, so its not a hardware performance issue. We're able to duplicate this issue on a RHEL 4 release 5 box also when we reach 1000+ connections using the same config files. Is there a setting that needs adjusting so connections timeout or some other config file misconfiguration? Any help would be much appreciated. Thank you.

(ITS#5274) add search to online docs

Full_Name: Craig Sebenik Version: 2.3.35 OS: CentOS 4.5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (209.220.152.66) It would be helpful if the admin documentation on the OpenLDAP web pages had some way to search. http://www.openldap.org/doc/admin24/ IMO, it would be fantastic if there was a simple search box on each page and an "advanced search page" with more options. However, a simple search box on just the main page would be a great start.
