Re: Initialize ldap with mdb
by rammohan ganapavarapu 03 Oct '17

Quanah, Quick question regarding "maxsize" in mdb, slapd-mdb man page says we have to preallocate the db size based on future growth of your data, that means will it create a data.mdb of maxsize? what i read from docs is, mdb loads whole database into memory, is it right? if my db size is grater then my RAM how does mdb handles? do we have any configuration options to set RAM allocation for mdb as i may have other applications sharing the same RAM?

Are you positive the servers are in sync at this point? I.e., did you freshly reload from whatever you consider your golden master them after applying the patch? --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Quanah, My slapd.d dir is empty and my initialization script only create config if slapd.d dir is empty, i tried with slapd.conf every thing looks good except i don't find a way to connect to cn=config db as i don't see roodDN in "cn\=config/olcDatabase\=\{0\}config.ldif" Thanks, Ram On Mon, Oct 2, 2017 at 1:35 PM, Quanah Gibson-Mount <quanah(a)symas.com> wrote: > --On Monday, October 02, 2017 2:19 PM -0700 rammohan ganapavarapu < > rammohanganap(a)gmail.com> wrote: > > >> >> Hi, >> >> >> >> I am trying to follow this thread ( >> http://blog.roeften.com/2015/03/openldap-24-on-centos-7-using-mdb.html ) >> to initialize the ldap config in non-default directory but i am getting >> this error. >> >> >> cat example.ldif | slapadd -v -F /opt/data/slapd.d -n 0 -d -1 >> >> >> >> >> 59d29ce6 >>> dnPrettyNormal: <cn=config> >> 59d29ce6 <<< dnPrettyNormal: <cn=config>, <cn=config> >> 59d29ce6 str2entry: entry -1 has multiple DNs "cn=config" and >> "cn=module,cn=config" >> slapadd: could not parse entry (line=1) >> >> >> If i add one by one (one dn at a time) it seems to be working. >> >> >> Any idea? >> > > Well, if you already have your own cn=config database, then you're just > making a real mess out of it.

Well, if you already have your own cn=config database, then you're just making a real mess out of it. That would be my guess. I'm not sure why you're following some random "how to" guide. If you already had a working slapd.conf, then all you needed to do was convert it to cn=config using "slaptest". --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Oh, I thought you had said you only had two masters. This could well be ITS#8444 (ignore the ITS title, it has nothing to do with memberOf), where there are out of sync problems with 3+ MMR nodes and delta-syncrepl when syncprov checkpoints. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Initialize ldap with mdb

Hi, I am trying to follow this thread ( http://blog.roeften.com/2015/03/openldap-24-on-centos-7-using-mdb.html ) to initialize the ldap config in non-default directory but i am getting this error. cat example.ldif | slapadd -v -F /opt/data/slapd.d -n 0 -d -1 59d29ce6 >>> dnPrettyNormal: <cn=config> 59d29ce6 <<< dnPrettyNormal: <cn=config>, <cn=config> 59d29ce6 str2entry: entry -1 has multiple DNs "cn=config" and "cn=module,cn=config" slapadd: could not parse entry (line=1) If i add one by one (one dn at a time) it seems to be working. Any idea? Thanks
