Re: OpenLDAP 2.3 to 2.4 Migration Question
by Razi Ahmad 20 Aug '19

20 Aug '19

Thanks, Quanah. I did that and see that memberof was populated. However, I also noticed that the number of groups returned when I query for the memberOf attribute on one account doesn't match the number of groups returned when I search for all groups that this particular user is a member of. Do you have any ideas what could be the cause of this mismatch or where I should look when troubleshooting? I checked a few other accounts and the numbers match.

OpenLDAP 2.3 to 2.4 Migration Question
by Razi Ahmad 20 Aug '19

20 Aug '19

Hi, I'm working on migrating from OpenLDAP 2.3 to 2.4. I've got my 2.4 provider set up and customized and have a copy of production data to load. I'd like to know if there's any way to have the memberof attribute populated during the process of loading the data. I used slapadd but when I searched for a user, I didn't see the memberOf attribute. Prior to running the slapadd command, I replaced the groupOfUniqueNames objectClass with groupOfNames and the uniqueMember attribute with member inside my LDIF file.

mdb index reporting available?
by Marc Roos 19 Aug '19

19 Aug '19

I used to have some help with what and how I should add indexes, but it looks like the new mdb backend is not telling me anymore. Is this correct? Anyway to get a warning when some index needs to be set? bdb_equality_candidates: (xxxx) not indexed bdb_inequality_candidates: (createTimestamp) not indexed etc https://mishikal.wordpress.com/2013/05/16/openldap-a-comparison-of-back-mdb…

PPolicy: Multiple pwdGraceUseTime attributes
by Ulrich Windl 19 Aug '19

19 Aug '19

Hi! I noticed that one user has multiple pwdGraceUseTime attributes like this: pwdGraceUseTime: 20190409095627Z pwdGraceUseTime: 20190605063107Z pwdGraceUseTime: 20190614121258Z pwdGraceUseTime: 20190723062401Z I don't understand: Doesn't the pwdGraceUseTime record how long/often the user may login despite of an expired password? For the example given, I assume the user has changed the password a few time since the inital grace login. So aren't the older pwdGraceUseTime attributes removed after the password was changed? Or can this happen if some admin chnages the password using some plain replace operation? Regards, Ulrich

Re: Multi-master replication : read_config: no serverID / URL match found. Check slapd -h arguments.

Hi, It is not as easy as you state it. I have a 2nd set up olcServerID: 1 ldap://abc1prdp01.abcgroup.com:1600 olcServerID: 2 ldap://abc2prdp01.abcgroup.com:1600 and SLAPD_URLS="ldapi:/// ldap://:1600/" This works too.

Fresh install changing the hdb to mdb

This is the default file that rhel/centos have in their slapd.d dir for the database. I thought I would just remove this one and place the one for mdb, seems to work, don't know about this entryUUID?

Initial syncreplication details
by Marc Roos 17 Aug '19

17 Aug '19

Am I correct to understand from this page[0] that the consumer gets its 'new' contextCSN from the slapcat import. (I saw it in the file). And will get all data since that date at startup? The replication id is of no influence. So if I would stop slapd import again the same old slapcat file. It would again receive all new data since that contextCSN? Regardless of the same rid being used with the provider. The idea behind this is that if you create a container with a default imported slapcat/slapadd file. Every time the task is stopped and started. It will go back to it initial container state. (unless you make it statefull of course) I am not adding that much data so I could make a new default image every week or so, this would be used every time a container is launched. (which only happens in a failover situation) [0] https://www.openldap.org/doc/admin24/replication.html

Environment variable in slapd config
by Marc Roos 16 Aug '19

16 Aug '19

Is it possible to reference an environment variable in olcSyncrepl: {0}rid= ? --On Saturday, August 10, 2019 6:54 PM +0200 Michael Ströder <michael(a)stroeder.com> wrote: > Are you talking about the serverID? > > serverID is not needed on a read-only consumer. Just leave it out. He's talking about replication ID (rid), and it's clearly out of bounds in his post. The slapd.conf/slapd-config man pages clearly document the allowed range that can be used for a RID. rid identifies the current syncrepl directive within the replication consumer site. It is a non-negative integer not greater than 999 (limited to three decimal digits --Quanah --
