mailHost
by Aravind Arjunan 25 Jul '08

25 Jul '08

hi, i had configured openldap in RHEL 5.1 operating system as master/slave for replication. It is working fine without any problem I had integrated openldap with my mailserver. mail server is in RHEL 5.1 OS and am using postfix. I have two mail box server in different location and two mail servers. unique users are existing in different mail servers The problem is when mail comes for a particular user it must go the respective mail box server. For that i need to mention in openldap a mailHost attribute. as you all know mailHost attribute is for specifying the location of mailbox. But in openldap misc.schema mailHoat attribute exits. When i add the misc.schema in slapd.conf file and if i add the mailHost attribute am getting error when i was restarting. And i had downloaded the qmail.schema from google and added that in schema directory as well as in slapd.conf Then i added the mailHost attribute. But when i specify the mailHost attribute as IP of my mailbox location, the mail is dropping by creating the IP as name.

Single master/multislave and passwords
by Bryan Payne 23 Jul '08

23 Jul '08

Our master is in dallas. One slave is in ohio. Our ohio users bind to their local server for speed's sake. This is obviously a problem if they change their password. Is there a way to bind locally but when it comes to updating passwords, it inform the master instead?

openLDAP, DCHP and DNS
by openLDAP 23 Jul '08

23 Jul '08

I would like to configure my openLDAP network using DHCP for my client machines. Is it necessary to have DNS names for all my clients, e.g. something.domain.com, for OpenLDAP to work properly or will it work as long as my openldap servers have fully qualified domain names?

password changing problems
by Ron Echeverri 22 Jul '08

22 Jul '08

I've set up OpenLDAP 2.4.10 and have been using phpldapadmin for user management. The machines in our QA environment are set up to allow LDAP users to log in, and they are also able to change their password via the passwd command. However, they are only able to do this once; if they attempt it again, it bounces back with "LDAP Password incorrect: try again". They are able to log out and in regardless, but passwd will not accept their password in order to change it. If the user's password is reset in phpldapadmin, again they are able to change the password once, and no more. There is no password policy configured in slapd; should there be? I have loglevel set to 296, but i'm not sure what to look for. thanks rone

Automatically create home directory uppon Email login
by Stelios A. 22 Jul '08

22 Jul '08

Hello all, I've migrate an old Sun Directory Server to OpenLDAP (version 2.4.9 on Ubuntu 8.04 server) and setup a master/slave with syncrepl for data replication betwwen 2 servers. 1st server hold the master ldap and second the slave along with the email server (Sendmail + Dovecot). Email server requires ofcourse a home directory with a mbox file etc. Is there a way to avoid creating each users home directory and setup then his/her permissions? There are 980 users in the base dc and trying to figure out a way to avoid creating all this directories along with chmod manually. I've already setup pam to auto create home directory uppon user login but problem is that only 5 users will have access via ssh. Any ideas? Thanks a lot

Client connect issues with OpenLDAP 2.3 on RHEL 4
by Martin Benson 22 Jul '08

22 Jul '08

I have a Red Hat Enterprise Linux v4.4 installation that runs OpenLDAP 2.2 using the provided Red Hat rpm's. I want to upgrade this to OpenLDAP 2.3 and have created an LDAP server using the packages from http://staff.telkomsa.net/packages/rhel4/openldap/i386 . The problem I have is that I cannot get a client to attach or query the server. I have installed the openldap2.3-clients and openldap2.3 packages and the server with logging enabled does not even show a connection. I suspect it is a problem with the nss_ldap package that comes bundled with RHEL 4.4. I cannot compile the software on my system as it is a partial install for clients of ours and does not get delivered with compiler software. Does anyone know of an updated rpm for nss_ldap to be compatible with openldap2.3 and RHEL 4? Has anyone done the install and written an install guide? Thanks Martin

memberOf search ACLs
by Andrew Bartlett 21 Jul '08

21 Jul '08

I've recently been trying to lock down Samba4's default ACLs, in it's generated LDAP backend configuration. I have memberOf configured to 'error' on dangling links, which I need for Samba. But I seem to be having some trouble with ACLs. I've attached my full config file, but the key part is: access to dn.base="" by dn=cn=samba-admin,cn=samba manage by anonymous read by * read access to dn.subtree="cn=samba" by anonymous auth access to dn.subtree="${DOMAINDN}" by dn=cn=samba-admin,cn=samba manage by * none If I change the last line to 'by * read', then the error is returned, but otherwise (due apparently to "" being unable to read the entry to validate it's existence). Shouldn't the search operations happen as the rootdn or memberof-dn, or am I missing some other configuration element here? In trying to fix this, I looked at what seemed to by typos in memberof.c, the patch of which I attach, but this didn't help. Any thoughts? Thanks, Andrew Bartlett -- Andrew Bartlett http://samba.org/~abartlet/ Authentication Developer, Samba Team http://samba.org Samba Developer, Red Hat Inc.
