reordering email aliases ?
by Frank Bonnet 08 Nov '10

08 Nov '10

Hello I'm facing a cosmetic problem with email aliases. Some users has aliases for their email adresses some has not. For example a professor named Jean Dupont has two valid email adresses : dupontj(a)domain.tld ( which is unixlogin(a)domain.tld ) j.dupont(a)domain.tld ( which is the alias that point to duponj(a)domain.tld ) Students have only one email adress of the form : unixlogin(a)domain.tld In many applications we use LDAP to fetch the user's email address and other data. The problem is sometime we get unixlogin(a)domain.tld and sometime we get emailalias(a)domain.tld I would like to do the following : if a user has an alias of the form emailalias(a)domain.tld then display it first Is it possible to reorder my LDAP database to do so ? Thanks a lot !

Abou 'make test'
by su heng 07 Nov '10

07 Nov '10

Hi All, I encountered an error when I was installing openLDAP. I mean 'make test' It gave me a message at the end of the output message: ... ... No race errors found after 10 iterations Found 2 errors >>>>>> Exiting with a false success status for now >>>>> ./scripts/test058-syncrepl-asymmetric completed OK for hdb. make[2]: Leaving directory `/home/suheng/Downloads/openldap-2.4.23/tests' make[1]: Leaving directory `/home/suheng/Downloads/openldap-2.4.23/tests' He said I had 2 errors encountered, however, I couldn't locate where the error is. Although I can install it, I worried about if it works fine. So, How can I locate the error location when I do 'make test'? Thanks & Best Regards, Su Heng

Configuring the chain overlay with cn=config
by Jaap Winius 07 Nov '10

07 Nov '10

Hi folks, My old chain configuration in slapd.conf works fine and looks like this: ################################################# moduleload back_ldap overlay chain chain-uri ldap://ldaps.example.com:389/ chain-rebind-as-user TRUE chain-idassert-bind bindmethod=simple binddn="cn=ldaps2,dc=example,dc=com" credentials=bilineatus mode=self chain-return-error TRUE ################################################# (Debian lenny, slapd v2.4.11-1) Some research has led me to believe that the proper cn=config equivalent in LDIF format would start like this: ################################################# dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: {1}back_ldap dn: olcOverlay={0}chain,olcDatabase={1}hdb,cn=config objectClass: olcOverlayConfig objectClass: olcChainConfig olcOverlay: {0}chain ################################################# (Debian squeeze, slapd v2.4.23-6) Does that look correct? If so, could someone please explain how to translate the other chain overlay directives I've used as well? I've tried translating the old configuration with slaptest, but it seems to ignore the existing chain configuration completely -- not even the back_ldap module gets loaded as a result. I've also tried searching the schema for them with this command: ~# ldapsearch -LLQY EXTERNAL -H ldapi:/// -b cn=schema,cn=config \ -s base | grep -A 2 -i chain However, the list of candidates that I've found with it seems incomplete: slapd.conf chain overlay directive => cn=config equivalent attribute ---------------------------------------------------------------------- chain-cache-uri => olcChainCacheURI chain-chaining => olcChainingBehavior chain-idassert-bind => ?? chain-max-depth => olcChainMaxReferralDepth chain-rebind-as-user => ?? chain-return-error => olcChainReturnError chain-uri => ?? ?? => olcChainConfig ?? => olcChainDatabase Can anyone fill in what's missing? Thanks, Jaap

Syncprov checkpoint and sessionlog with cn=config
by Jaap Winius 06 Nov '10

06 Nov '10

Hi folks, When configuring a sync provider with cn=config, it was not too difficult to figure out how to load the syncprov module and create the entry for its overlay, but it is unclear how to configure two associated statements that appear as follows when using slapd.conf: syncprov-checkpoint 100 10 syncprov-sessionlog 100 Can anyone say how this might be accomplished? Thanks, Jaap

Syncrepl filtering
by Bram Cymet 06 Nov '10

06 Nov '10

Hi, I would like to control what gets replicated to my ldap slaves. How would I specify what I don't want to be replicated? Is this even possible or do I have to create a filter that finds everything that I want to send down? Thanks, -- Bram Cymet Software Developer Canadian Bank Note Co. Ltd. Cell: 613-608-9752

Accesslog overlay to get IP from user connection
by Alberto Frontera 06 Nov '10

06 Nov '10

Hello this is my scenario: - Centos 5.2 - ldap 2.420 - Mysql 5.07 Ldap is used to authenticate users from Ubuntu systems. We want to storage some info from the connections: - date - IP I can see this info on ldap logs, but i want to save this info on a ldap DB (mysql backend if possible). Actually i have configured accesslog overlay, but i think this info is not registered or i can not see it. :p The question is: is access overlay the tool to register this info? (i think the answer is no) ... and if it is not, how can i do this? I need some advice on this. Thx

Hey guys, And sorry to Quanah for the type-o. ;) At any rate thanks for the ldapsearch.

Any further ideas on why this isn't working? Thanks!

loglevel question / problem
by Aaron Bennett 05 Nov '10

05 Nov '10

Hi, I have two reasonably identical Ubuntu Server 10.04 boxes running OpenLdap 2.4.21. ( I say reasonable identical because one is a master and the other pulls via syncrepl ). The master box is sending copious amount of query log info to syslog -- it looks like it's logging every search and connection. The other box looks like it's only logging syncrepl information to the debug facility. What I can't figure out is how this is happening. When I started, neither machine had olcLogLevel entries in cn=config.ldif ; I have since added olcLogLevel: none (no effect) and even olcLogLevel: 0 to the master, restarting slapd each time. I've verified that it's not getting any "-d" switch on startup, both by looking at the SLAPD_OPTIONS in /etc/default/slapd and with ps -ax (which shows /usr/sbin/slapd -h ldaps:/// ldap:/// ldapi:/// -g openldap -u openldap -F /etc/ldap/slapd.d). Here's sample syslog output from the master: Nov 5 07:48:06 nyx slapd[5100]: conn=1008 op=1357 SRCH attr=mailRoutingAddress Nov 5 07:48:06 nyx slapd[5100]: conn=1008 op=1357 SEARCH RESULT tag=101 err=0 nentries=0 text= Nov 5 07:48:06 nyx slapd[5100]: conn=1008 op=1358 SRCH base="dc=clarku,dc=edu" scope=2 deref=0 filter="(|(mail=@clarku.edu)(mailAlternateAddress=@clarku.edu))" Nov 5 07:48:06 nyx slapd[5100]: conn=1008 op=1358 SRCH attr=mailRoutingAddress Nov 5 07:48:06 nyx slapd[5100]: conn=1008 op=1358 SEARCH RESULT tag=101 err=0 nentries=1 text= Nov 5 07:48:06 nyx slapd[5100]: conn=1007 op=10647 SRCH base="dc=clarku,dc=edu" scope=2 deref=0 filter="(|(mail=clarku.edu)(mailAlternateAddress=clarku.edu))" And here's sample from the slave: Nov 5 07:54:21 erebus slapd[7913]: syncrepl_entry: rid=001 be_modify uid=dgoldman,ou=Users,dc=clarku,dc=edu (0) Nov 5 07:54:21 erebus slapd[7913]: slap_queue_csn: queing 0x7f730550e7e0 20101105115421.300608Z#000000#000#000000 Nov 5 07:54:21 erebus slapd[7913]: slap_graduate_commit_csn: removing 0x7f730407f560 20101105115421.300608Z#000000#000#000000 Nov 5 07:54:21 erebus slapd[7913]: do_syncrep2: rid=001 cookie=rid=001,csn=20101105115421.483388Z#000000#000#000000 Nov 5 07:54:21 erebus slapd[7913]: syncrepl_entry: rid=001 LDAP_RES_SEARCH_ENTRY(LDAP_SYNC_MODIFY) Is there some other place that this information could be living?

openldap 2.4.2[13] socket close bug ?
by Arjan Filius 05 Nov '10

Hello openldap ml, while researching more or less regular xen/centos/openldap crash situation, i ran into a situation which i think is a (openldap) bug. Tested with self compiled/packed openldap 2.4.21 and 2.4.23 on centos 5.2 64 bits The most easy way to explain and test (for me) is: 1) Set threads to 2 in slapd.conf 2) Start a ldap search query which takes some time (say longer then a minute or so) ps: local or remote ldapsearch doesn't matter ps: i used ldapsearch and a "slowcat" to simulate 3) start a second ldap search querry as with 2) 4) Try to start a third ldapsearch query, which you may notice would connect (tcp backlog), but not yet handled by slapd. Normally when the first ldapsearch session would stop, the third session will be handled by slapd, which works just fine as expected, no need to test that now. >From now on you have some slightly different situations, which i will number 5a ....) 5a) while those first 2 sessions are still running, and session 3 is waiting, lets kill session 1 or 2, and here it happens: -slapd won't log the killed session, and the third session isn't going to handled. -The third session is going to be handled as soon as the second session finishes in a normal way. 5b) while those first 2 sessions are still running, and session 3 is waiting, kill all ldap search querries (press ^C within your ldapsearch for example) , and here it happens: -slapd won't log died sessions -new ldapsearch sessions are accepted by the backlog buffer, but are never going to be accepted by the slapd process. -when stopping slapd it complains about closing already died sessions/socket. So it looks like killed sessions, are not quite handled correctly within slapd, and i noticed as soon there is one session which finishes in a normal way, it will also clear and free the killed sessions. The other way arond, when killing all sessions, you've a denial of service, and no session will ever be cleared. Please confirm or deny, feedback welcome. Regards, -- Arjan Filius iafilius(a)xs4all.nl
