meta config help

We are attempting to setup a configuration that would allow us to bind/search 2 different back-ends with 2 completely different suffixes. Below is our configuration and the error we get back. We are able to connect to both back-ends provided the other is commented out in the slapd.conf file so we are sure the suffix change works for both targets. [slapd.conf] database meta suffix "dc=virtual" lastmod off #rebind-as-user uri "ldap://foo.wuaddev.wustl.edu/dc=virtual" suffixmassage "dc=virtual" "ou=Users,ou=Persons,dc=wuaddev,dc=wustl,dc=edu" #uri "ldap://bar.wustl.edu/dc=virtual" #suffixmassage "dc=virtual" "OU=users,OU=ais" [search command] -bash-3.00# ldapsearch -h localhost -v -b 'dc=virtual' -s sub -D 'cn=ssbinduser,dc=virtual' -w 'foobar' 'cn=ssbinduser' ldapsearch: started Tue Jun 17 13:28:59 2008 ldap_init( localhost, 389 ) ldap_simple_bind: Operations error [Debug output of /usr/local/libexec/slapd] Ldap Err: DSID-0C0906 2B, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, vece.

Just a note: this project has not been abandoned. In fact the "set" functionality of OpenLDAP now supersedes AACLs: http://www.openldap.org/faq/data/cache/1133.html Regards, Raphaël Ouazana.

Openldap fine grained / advanced ACLs
by Faraz R. Khan 17 Jun '08

17 Jun '08

Is it possible to have fine grained ACLs in OpenLDAP? My problem is that the 'write' access is too broad. I wish to be able to control ADD, modify and delete separately. I tried looking at aacls.sourceforge.net but it involves the setup of a separate server and looks abandoned. Any pointers would be appreciated- maybe the denyop module? I was trying to find some docs but all I could find was a FAQ entry. Any pointers would be welcome. Thank you. -- Faraz R Khan Chief Architect Emergen Consulting Pvt Ltd +92.21.529.0381 x200 www.emergen.biz

Ya i had tried through schema, in internet. It was mentioned tat we can create our own schema for eg: test.schema and we can add the list off attributes that are required for us. I have tried that also but it was not working. I will tell the objective of mine. we have mailserver in RHEL 5 and ldap server is separate. we have all the user information in ldap server including mail id mail box location and other things related to mail and organization. so when a user sends mail the information must want to fetched from ldap server and work accordingly. somehow please help with this issue.Since i need some help from you guys. And thanks in advance.

openldap
by Aravind Arjunan 17 Jun '08

Hi, I had configured openldap 2.3.27-5 in RHEL 5 operating systems. my ldap is acting as a master slave. I have no problem with that, the changes what i make in master is getting replicated to slave. What i need to know is, I had to certain attributes to my openldap server. for eg: when i add an attribute called ' mail ' for specifying mail address and in the ldif file and if i add that ldif file using 'ldapadd' command am getting, ldap_add: Object class violation (65) additional info: attribute 'mail' not allowed What i need to do for adding this attribute. tell me the correct objectclass for this attribute.

syncrepl in OpenLDAP 2.3.x and updating on a replica
by Filipe Brandenburger 17 Jun '08

17 Jun '08

Hi, I have a setup with two CentOS 5 machines running OpenLDAP 2.3.x, right now the primary uses slurpd to send the updates to the second server, and the second server is using "updatedn" to allow updates (from what I understand! I'm no OpenLDAP guru here.) Clients are using pam_ldap and nss_ldap to get the users and authenticate them in LDAP. Right now hosts query only the primary LDAP server, that is the address set on the "host" variable of /etc/ldap.conf. Changing password with "passwd" works fine, and the password is correctly replicated to the secondary server. Now, first thing, I wanted to load balance between the two servers. The way I did it was to register a Round-Robin DNS record, with one A entry for each server IP, and I used that entry in the "host" variable of /etc/ldap.conf. Everything worked. Queries going each time to a different server. I was expecting to have problems changing passwords, but amazingly it worked. Apparently when a password change request goes to the second server, that server will do a query on the first server to do the password change, and then (through slurpd) the change gets replicated on the second one. Everything great. (Is there a better configuration for pam_ldap and nss_ldap on /etc/ldap.conf for load balancing other than round-robin DNS?) Now, I was reading that syncrepl is superior to slurpd, and that syncrepl is the preferred method of replication. I actually saw that it's true when I saw that it actually replicated the master without having to stop it and copy the dbs (which is necessary with slurpd.) I even saw that in OpenLDAP 2.4.x slurpd is deprecated/discontinued and only syncrepl is supported. So I'm trying to migrate from slurpd to syncrepl. And so far everything is working fine in my test environments. This is what I have configured on the master: overlay syncprov syncprov-checkpoint 1 10 syncprov-sessionlog 100 And on the slave: syncrepl rid=1 provider=ldap://ldap1.mydomain.com type=refreshAndPersist searchbase="dc=mydomain,dc=com" schemachecking=off bindmethod=simple binddn="cn=Manager,dc=mydomain,dc=com" credentials=xxxxxxxxxxx updateref ldap://ldap1.mydomain.com/ It works with queries, and when I do an update on the master, it replicates fine to the slave. But when I try to do some change on the slave, that's what I get: $ ldapdelete -H ldap://ldap2.mydomain.com/ -D cn=Manager,dc=mydomain,dc=com \ -w XXXXXXX -x uid=usertodelete,ou=Users,dc=mydomain,dc=com ldap_delete: Referral (10) referrals: ldap://ldap1.mydomain.com/uid=usertodelete,ou=Users,dc=mydomain,dc=com I would like to have something closer to what happens when using slurpd, which seems to be more transparent to clients. I tried to set "updatedn" but slapd complained that it is supported when using slurpd. I also tried to start configuring overlay on the slave and syncrepl on the master, but when I do that I can't run updates on either side, both of them end up being read-only. I read that on OpenLDAP 2.4.x Administration Guide, on the section about multi-master replication, but I then saw that multi-master replication is supposed to work only on 2.4.x, and not on 2.3.x, so that's apparently not an option. So I ask: is there a way to configure OpenLDAP so that the slave (running syncrepl) can send updates to the master when receives from a client? Or (not as good but still an option): If I use "updateref" to send Referral, how can I make sure the tools (ldapdelete, ldapmodify, ldapadd, ...) actually *follow* the referral (I looked for that in man pages and didn't find any obvious options for that)? And more important, will pam_ldap and nss_ldap follow those referrals when changing the password? Do I have to set something on /etc/ldap.conf for that? Upgrade to 2.4.x is something I would like to avoid, since I would rather stick with what is supported by CentOS 5. Sorry for the long e-mail! Any help and advices will be appreciated. Thanks a lot!
