Floating point numbers in ldap
by Lorenzo Pastrana 16 Dec '08

16 Dec '08

I can't find any mentions of floating point/real data types in ldap attributes syntax, I've been reading the laconic 'Numeric Sting' specifications : 6.23. Numeric String ( 1.3.6.1.4.1.1466.115.121.1.36 DESC 'Numeric String' ) The encoding of a string in this syntax is the string value itself. Example: 1997 Would this work ok (matching & ordering) with a 1.997 value ? If not, how do I get ldap to match and order floating point scalars ? Thanks. Lo.

slapd won't run as service
by Eddie Grenier 16 Dec '08

16 Dec '08

I've installed, configured and run OpenLDAP on my server. However, if I try to run it as a service using "service ldap start" it doesn't run. Also, the configuration file step returns "OK" as does the starting slapd step. I've narrowed it down to the fact that if slapd is run as user root things work just fine. I've already done "chown -R ldap:ldap /var/lib/ldap" but that doesn't seem to help. Here is the output I see when trying to run as user ldap: slapd startup: initiated. bdb_db_open: dc=edwaa,dc=com bdb_db_open: dbenv_open(/var/lib/ldap) bdb(dc=edwaa,dc=com): Invalid log file: log.0000000001: No such file or directory bdb(dc=edwaa,dc=com): PANIC: No such file or directory bdb(dc=edwaa,dc=com): PANIC: DB_RUNRECOVERY: Fatal error, run database recovery bdb_db_open: dbenv_open failed: DB_RUNRECOVERY: Fatal error, run database recovery (-30978) backend_startup: bi_db_open(0) failed!

Any ideas would be much appreciated!

ACL for DIT structure rules
by Mansour Al Akeel 15 Dec '08

15 Dec '08

Hello all, In a previous email, I was told that we can implement *DIT* *structure* rules with openldap using ACL (http://www.openldap.org/lists/openldap-technical/200811/msg00152.html). Did any one have any success implementing these rules with ACL. I have searched the net for an example, but out of luck. Possibly a simple example will help a lot, just to give me an idea about the syntax for a DIT structure rule using ACL. Thank you.

Re: OpenLDAP replication

Gavin, Thanks for your help. That appears to be working. In a failure situation where rid=1 goes down, and writes began occuring to rid=2, when I bring back up the server which was set to rid=1, what is the proper way to get them back in sync? Would it be just to change the rids and reload openldap? - Justin Lintz On Mon, Dec 15, 2008 at 2:57 PM, Gavin Henry <ghenry(a)openldap.org> wrote: > > ----- "Justin Lintz" <jlintz(a)gmail.com> wrote: > >> Quanah, >> >> Looking at >> http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master >> it appears the example is with using cn=config to store the >> configuration.

Querying Attribute Type Definitions Problem
by Kevin Hardiman 15 Dec '08

15 Dec '08

I am trying to query the definition of an attribute type using one of the attribute type's aliases. For example, given: attributetype ( 2.5.4.3 NAME ( 'cn' 'commonName' ) DESC 'RFC2256: common name(s) for which the entity is known by' SUP name ) I am using Java's naming API to query the definition, and getting an exception saying the attribute type doesn't exist. Example: DirContext cnSchema = (DirContext)schema.lookup("AttributeDefinition/commonName"); I appreciate that this is not a Java list - I am trying to determine if what I am seeing is consistent with one of the many LDAP RFC's (i.e. I must use the actual attribute type's name to get the definition). If not I'll peddle my query elsewhere :) Thanks, Kevin Hardiman

schemacheck && valid objects check - just to note slapd behaviour
by Piotr Wadas 15 Dec '08

15 Dec '08

Hello, Using openldap 2.4.10 (x86), bdb backend. I had custom objectClass. I made it to be structuralObjectClass , and then created some object of this class in DIT. Everything works fine. Then (actually weeks later), I edited my objectClass definitionas, and made my custom objectClass to be an auxiliary class, and restarted slapd - everything was still working fine. Schema syntax is still valid, no schemacheck warnings. Then I did a slapcat dump - I realized what happened when came up, that I cannot load dump back with slapadd, because it contains objects, which, actually should generate errors. slapcat backups I did in the meantime was actually useless and I didn't note it. Now, I don't expect slapd to remove or ignore such objects, anyway while SERVING (returning), or indexing existing object of such kind, I'd expect some warning, that existing object does not conform existing schema. Or some tool to verify existing directory objects to find out about such situation - imagine if I hadn't been trying to retrieve from it for months, I wouldn't have learned it became useless :) May I please for some comments on such issue ? Regards, Piotr Wadas

Quanah, Looking at http://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master it appears the example is with using cn=config to store the configuration. Is there an example somewhere with just using slapd.conf? - Justin Lintz On Thu, Dec 11, 2008 at 6:13 PM, Quanah Gibson-Mount <quanah(a)zimbra.com> wrote: > --On Thursday, December 11, 2008 4:30 PM -0500 Justin Lintz > <jlintz(a)gmail.com> wrote: > >> Quanah, >> >> I'm still seeing the issue after making the change.

Quanah, Thanks for your quick reply. I've made the change. I thought I had taken it from the openldap documents but clearly did not after reviewing them, I must have gotten mixed up with all the tabs I had open. Looks like its best to stick to the official documents (and this mailing list) rather than the how-tos out there - Justin Lintz On Tue, Dec 9, 2008 at 9:21 PM, Quanah Gibson-Mount <quanah(a)zimbra.com> wrote: > --On Tuesday, December 09, 2008 6:05 PM -0800 Quanah Gibson-Mount > <quanah(a)zimbra.com> wrote: > >> --On Tuesday, December 09, 2008 4:45 PM -0500 Justin Lintz >> <jlintz(a)gmail.com> wrote: >> >>> Hi, >>> >>> I am currently working on trying to configure replication between 2 >>> ldap servers.
