hello all, we are trying to setup a ldap server which uses the mysql as back-end instead of bdb backend.we have installed slapd and ldap-utils in debian-etch .we also have installed mylibodbc, mysql-client-5,mysql-server-5. we have established the mysql-ODBC connectivity and tested the connectivity using isql.we have configured the slapd.conf file to connect mysql and when we tried to add entries using ldapadd , we get the following err ldap_add: Server is unwilling to perform (53) additional info: operation not permitted within namingContext this is the slapd.conf file # This is the main slapd configuration file.

LDAP Writes are not propagated to mirror nodes.

Hello All, I am trying to setup Mirror Mode of replication. Using the configuration files listed below for 2 node setup. The database comes up and after every 2 or 3 writes, the data is not pushed onto the other mirror node. This is happening on both the mirror nodes. I am getting the following error: slap_client_connect: URI=ldap://135.254.229.102:389 DN="uid=<UID>,o=csosso_arc" ldap_sasl_bind_s failed (-1) slap_client_connect: URI=ldap://135.254.229.102:389 DN="uid=<UID>,o=csosso" ldap_sasl_bind_s failed (-1) This is happening after 2 or 3 write operations to the database.

ldap group name resolving problem
by Christian Weihrauch 03 Mar '08

03 Mar '08

Hi, I have problems with debian etch Linux clients resolving group names served by our LDAP server. user and passwd work because I can login properly. "getent group" properly shows the group served by the LDAP server. eg: #getent group mygroup:x:1000:chris However "id username" only shows LDAP served groupIDs but not their names. eg: #id chris uid=1002(chris) gid=1000 groups=1000,20(dialout) This means that I can't do things like chgrp eg: "chgroup mygroup directoryname" gives: "chgrp: invalid group `mygroup'" I am using nscd and nsswitch.conf says: passwd: files ldap group: files ldap shadow: files ldap Any ideas? Thanks! -- Christian Weihrauch, The University of Reading

Help with SASL/GSSAPI to remote Kerberos server
by Wes Modes 01 Mar '08

01 Mar '08

I am using *SASL/GSSAPI* to authenticate to* Kerberos* from *OpenLDAP*. I haven't gotten that to work yet. To separate and modularize some of these services, we have three servers: A file server running Samba; A directory server running OpenLDAP to provide personal and group identities; and an authentication server running Kerberos (administered by another group). Samba connects to OpenLDAP through smbldap-tools. And OpenLDAP connects to the Kerberos server via SASL/GSSAPI. When someone requests a Samba logon, Samba requests an LDAP bind, which in turn should use SASL to authenticate via Kerberos. The connection between Samba and OpenLDAP is working swell. It is the Kerberos connection that has me flummoxed. *Simply put, OpenLDAP with SASL2 and GSSAPI support will be running on one server, while the Kerberos KDC will be running on another server.* I haven't found any documents that address this not-so-wacky design. Almost all of the docs I found presume that I am setting up the KDC on the same server at OpenLDAP. In my case, the KDC is administered by another group who is willing to grant me access to Kerberos. However, none of the docs I've found offer help in setting up SASL/GSSAPI here and the Kerberos server elsewhere. So when a document says, run /kadmin.local/, to generate a principle, that is not available to me. If I can ask specifically for what I want, I might be able to convince the kerberos administrators to do it for me, but I have to be pretty specific about what I want. The docs I'm referring to are Cyrus SASL for System Administrators http://www.sendmail.org/~ca/email/cyrus/sysadmin.html <http://www.sendmail.org/%7Eca/email/cyrus/sysadmin.html> OpenLDAP 2.2 Administrator's Guide - Using SASL http://www.openldap.org/doc/admin22/guide.html#Using%20SASL In several documents, it was suggested that before you try connecting OpenLDAP to Kerberos that you test to make sure your Kerberos configuration is working. That makes a lot of sense to me. So I want to perform a series of checks, but I don't know what those tests might be. Here's what I would like to test: * Can I connect to the Kerberos server directly? (kinit) * Is direct authentication to the Kerberos server working? * Am I getting returned a proper ticket? (klist) * Is the keytab file on my OpenLDAP server being recognized and accepted by the Kerberos server? * Is my machine being authenticated as a principle? Does it need to be? * How do I test SASL2 before getting OpenLDAP involved? * After making changes to my OpenLDAP config, how do I test the Kerberos connection through OpenLDAP? Do you have any pointers here? This project has been delayed weeks and weeks while I climb and climb up Samba, OpenLDAP, and Kerberos' very steep learning curve. So your prompt response will be hugely helpful. Thanks in advance, Wes Specifics of my configuration: * OS: Red Hat Enterprise 4 v2.6.9 * OpenLDAP v2.2.13 * Local MIT Kerberos5 v1.3.4 * KDC: MIT Kerberos5 v? * Cyrus SASL v2.1.19 -- Wes Modes Server Administrator & Programmer Analyst McHenry Library Computing & Network Services Information and Technology Services 459-5208

Missing Syntax
by Nik Svoboda 29 Feb '08

29 Feb '08

I have noticed that in the openldap system I am using, the schema has a missing syntax. This syntax is "1.3.6.1.4.1.1466.115.121.1.58" ; "Substring Assertion". This is referenced in matching types using partial matching of strings (exactsubstringsmatch, numericStringSubstringsMatch, ...). I am fairly new to these subjects and do not understand fully how they operate. Is there a way to correct this? Are the syntaxes and matching types specified in a way that can be modified dynamically? -Nikkos

RWM overlay bind operation
by Rui Ramos 28 Feb '08

28 Feb '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello *, I'm having some troubles with the rwm overlay maybe someone can give some ligths on the subject. We have a non standard schema which in turn has an atribute pass1 that we want to use for the LDAP BIND operation. From what i've seen the BIND operation is hardcoded to use userPAssword attribute (please correct me if i'm wrong). So what we did was the following: we have server A with pass2 filled running on port 7001. and server B with the following config ... database ldap suffix "dc=example,dc=org" uri "ldap://localhost:7001" overlay rwm rwm-map attribute userPassword pass2 ... With this configuration the attribute userPassword gets filled with the content of pass2. But if we try to make Bind search in server B with that user password it fails because it tries to make the bind in ldap://localhost:7001. Is there a way to make the bind operation the the changed data ?

ldapsearch returns Could not create LDAP session handle (3): Time limit exceeded
by Brooks Campbell 28 Feb '08

28 Feb '08

We upgraded some client servers from RedHat ES3U4 to Redhat ES4U2 and now the ldapsearch string we used in our monitoring software to check if the customers openldap server is working is returning errors. We were using: ldapsearch -x -H ladps://host.domain.com:636 Which worked find with the open ldap-client on redhat 3 (I do not no the version number) but in redhat 4 openldap-clients 2.2.13-3 we get the error "Could not create LDAP session handle (3): Time limit exceeded" immediately. Ldap is working our application authenticates users it is just the ldapsearch we are using to monitor the service which seems to not be working. Does anyone see anything wrong with the line above or is there something else we can use in a automated script to check if the ldap server is running?

OpenLDAP question
by Keith Conger 28 Feb '08

28 Feb '08

Hi, I was wondering if the following is possible with OpenLDAP: I'd like to have an OpenLDAP Server or two(load balanced) with an extended custom schema that will proxy certain attributes back to a non-openldap ldap server. Reading through the list archives it seems like it may be possible but does anyone know for sure from experience?
