very slow queries sometimes with alias deref always and scope sub
by COMBES Julien - CETE Lyon/DI/ET/PAMELA 22 Dec '07

22 Dec '07

Hello, I have a strange problem on all of my openldap servers (master and slaves). In general, requests with alias always dereferenced and scope sub on an attribute indexed are working correctly and answers come in a few milliseconds. But sometimes , during some hours, on all my openldap servers, the same queries are taking a few seconds to be returned (between 10 to 45s). During this time all queries with alias never dereferenced are working correctly. For the openldap master, which is only used to write entries and for slurpd replication, the load average is between 0.2 and 0.5 during the problem. For others servers that have more requests, the load average is growing up. I don't find the reasons which cause the problem. All is coming back to normal performance after the night. I use debian etch openldap package wich provide openldap 2.3.30. My directory has around 150000 entries. I use bdb database. I have somes tuning on DB_CONFIG that I could give, if you think that it could have an interest. For exemple : -> During problem : - with alias deref *never* $ time ldapsearch -x -LLL -H ldap://master.my.domain -b "dc=my,dc=domain" -s sub -a never uid=jean.talus.i <ldap answer> real 0m0.007s user 0m0.004s sys 0m0.000s - with alias deref *always* $ time ldapsearch -x -LLL -H ldap://master.my.domain -b "dc=my,dc=domain" -s sub -a always uid=jean.talus.i <ldap answer> real 0m47.225s user 0m0.004s sys 0m0.000s $ time ldapsearch -x -LLL -H ldap://slave1.my.domain -b "dc=my,dc=domain" -s sub -a always uid=jean.talus.i Time limit exceeded (3) real 0m16.148s user 0m0.000s sys 0m0.004s and so on on all my openldap slaves servers. -> after the night, when it's working correctly again : $ time ldapsearch -x -LLL -H ldap://master.my.domain -b "dc=my,dc=domain" -s sub -a always uid=jean.talus.i <ldap answer> real 0m0.016s user 0m0.000s sys 0m0.004s $ time ldapsearch -x -LLL -H ldap://slave1.my.domain -b "dc=my,dc=domain" -s sub -a always uid=jean.talus.i <ldap answer> real 0m0.020s user 0m0.000s sys 0m0.004s I don't find anything that help me on internet. Do you know how can I correct this or what can it be the cause ? Is there some docs that could help me to tune my openldap servers to correct this ? Regards, Julien

Problems when following referrals with ldapsearch
by Antonio Alonso 22 Dec '07

22 Dec '07

Hi ! I have configured an slapd/back-meta (slapd_1) which redirects all LDAP messages to an slapd/back-bdb instance (slapd_2). This last slapd instance manages also some other referrals to other slapd/back-bdb instance (slapd_3) I have configured back-meta to follow the referrals. When sending an LDAPsearch to slapd_1 with a base that I have configured as a referral in slapd_2 (the acual data is stored in slapd_3) I see the "Referral (10)" result code in slapd_1 (I am tracing it) but the back-meta is NOT following that referral. I tried directly sending the LDAPsearch to slapd_2 using through the ldapsearch commnand (setting the ldap.conf option REFERRAL parameter to "yes") but I see exactely the same (the "10" resul code, the right "ref" parameter -pointing to the right entry in slapd_3) but the command is NOT following the referral. I tested it with the java LDAPBrowser tool (setting the "follow referrals" option) and it works properly (so now I am sure it is not a problem in the data stored in the backends involved). Do you know what I am missing? I do not know if I forgot some "configuration" option when compiling/creating the openldap libclient library (when installing openLDAP 2.4) as it is used in both ldapsearch and back-meta (so I am starting to think the problem is in that "common" component) ... NOTE: I have tried with referrals followng the "ldap://127.0.0.1: ...." and "ldap://localhost:..." patterns (as all slapd instances are running in the same machine) but I got the same error ....

ldap.conf between /etc/openldap or /etc/openldap2.3?
by R.B. 21 Dec '07

21 Dec '07

Hi; I've finally completed my server setup and now I'm focusing on the client configurations (with TLS). I'm using the Buchan RPMs (openldap 2.3.39) for RHEL4 and it creates an /etc/openldap2.3 directory. I also have the base openldap (2.2.x) rpms installed (originally) and it creates the base /etc/openldap directory. After doing an strace, I see that /etc/openldap/ldap.conf is used.... but I want use /etc/openldap2.3/ldap.conf file, how do I switch my ldap client to look here? Thanks, Rafael

Re: Overlay chain formatting

I agree. The man pages offer content that is not in the admin guide and are generally well written.

Test047 fails if "rwm" not configured
by Dave Horsfall 20 Dec '07

20 Dec '07

Just been playing with 2.4.7, and test047 was failing. It seems that it assumes that "rwm" is present; should I file an ITS? -- Dave Horsfall DTM VK2KFU Ph: +61 2 9552-5509 (direct) +61 2 9552-5500 (switch) Corinthian Eng'ng P/L, Ste 54 Jones Bay Whf, 26-32 Pirrama Rd, Pyrmont 2009, AU

If you've used any presence indexing or equality indexing of integer attributes, you'll need to run slapindex to get the new format. slapindex -q -t should do the trick. Obviously there've been a lot of other changes. There are still one or two new features in CVS that will show up in the next 2.4 release.
