remote credentials for local branch with authz-regexp
by Hugo Monteiro 23 Feb '11

23 Feb '11

Hello list, I'm using translucent in a local server. That same server also has an extra local database, which is a local only branch of the remote database. This database is a subordinate and they glue together well. Now, for the sake of management, i need to be able to identify to the local database (rootdn) but using credentials from the remote database. Assuming one has translucent to remote - dc=example,dc=com with remote admin user cn=admin,dc=example,dc=com local - ou=localbranch,dc=example,dc=com with rootdn admin user cn=admin,ou=localbranch,dc=example,dc=com I tried the follwing on the local server database hdb suffix "ou=localbranch,dc=example,dc=com" rootdn "cn=admin,ou=localbranch,dc=example,dc=com" rootpw "secret" directory "/var/lib/ldap/ou=localbranch,dc=example,dc=com" index objectClass,sambaSID eq lastmod on authz-regexp "cn=admin,dc=example,dc=com" "cn=admin,ou=localbranch,dc=example,dc=com" access to dn.base="ou=localbranch,dc=example,dc=com" by * read access to * by dn="cn=admin,ou=localbranch,dc=example,dc=com" write by dn="cn=admin,dc=example,dc=com" write by * read subordinate The credentials used to connect to the remote server have full read only access to the remote database. So the problem is that when i try to authenticate using cn=admin,dc=example,dc=com, to the local database branch, i can see the bind request being transluced to the remote server without using the authz-regexp map. Any advice is appreciated, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _

How can I check ldap is working well?
by Olivier PAVILLA 23 Feb '11

23 Feb '11

After upgrading my server (Lenny to Squeeze). Something happened. /var/lib/ldap was empty. Thanku very debian installer :) I made a new /var/lib/ldap/DB_CONFIG I restarted ldap with something like this /etc/init.d/slapd start I looked my syslog tail -f /var/log/syslog and it contents that : Feb 23 13:46:13 unverre slapd[4660]: slap_client_connect: URI=ldaps://coruscan2.dumpsize.fr:636 DN="cn=replicapalpatine,ou=useraccess,dc=dumpsize,dc=fr" ldap_sasl_bind_s failed (-1) Feb 23 13:46:13 unverre slapd[4660]: do_syncrepl: rid=008 rc -1 retrying Feb 23 13:56:13 unverre slapd[4660]: syncrepl_message_to_entry: rid=008 mods check (objectClass: value #4 invalid per syntax) Feb 23 13:56:13 unverre slapd[4660]: do_syncrepl: rid=008 rc 21 retrying Feb 23 14:06:13 unverre slapd[4660]: syncrepl_message_to_entry: rid=008 mods check (objectClass: value #4 invalid per syntax) Feb 23 14:06:14 unverre slapd[4660]: do_syncrepl: rid=008 rc 21 retrying Anyone can translate this to me?

authzTo now X-ORDERED?
by Michael Ströder 23 Feb '11

23 Feb '11

HI! I'm trying to configure proxy authz with 2.4.24 without luck testing with ldapwhoami -X. Now I wonder if attribute 'authzTo' is now handled as X-ORDERED [1]. Unfortunately the subschema subentry does not contain a attribute type description for 'authzTo'. The server adds prefix "{0}" to my authzTo attribute value. Ciao, Michael.

Re: openldap problems authenticating

Hey guys I took Quanah's advice and put the clear text password into /etc/lapd.conf on the client. I also noticed that the user account it was looking for was of a posixAccount class. And I was missing the nis.shema. So I added nis.schema to slapd.conf and restarted slapd and I was seeing the same pattern. ldapsearches on the client were working just as they were before and getents on the client were not. But I was seeing a new error in the logs at this point: Feb 23 01:16:45 LBSD2 slapd[52517]: conn=1471 op=1 SRCH base="ou=staff,dc=summitnjhome,dc=com" scope=2 deref=0 filter="(objectClass=posixAccount)" Feb 23 01:16:45 LBSD2 slapd[52517]: conn=1471 op=1 SRCH attr=uid userPassword uidNumber gidNumber cn homeDirectory loginShell gecos description objectClass Feb 23 01:16:45 LBSD2 slapd[52517]: conn=1471 op=1 SEARCH RESULT tag=101 err=32 nentries=0 text= Feb 23 01:16:45 LBSD2 slapd[52517]: daemon: activity on 1 descriptor Feb 23 01:16:45 LBSD2 slapd[52517]: daemon: activity on: Feb 23 01:16:45 LBSD2 slapd[52517]: 12r Feb 23 01:16:45 LBSD2 slapd[52517]: Feb 23 01:16:45 LBSD2 slapd[52517]: daemon: read activity on 12 Feb 23 01:16:45 LBSD2 slapd[52517]: daemon: select: listen=6 active_threads=0 tvp=NULL Feb 23 01:16:45 LBSD2 slapd[52517]: daemon: select: listen=7 active_threads=0 tvp=NULL Feb 23 01:16:45 LBSD2 slapd[52517]: connection_read(12): input error=-2 id=1471, closing.

openldap problems authenticating

I've broken my installation
by Stuart Bailey 22 Feb '11

22 Feb '11

Hello, I had a working openldap installation that I was developing some PHP to manage. I'm using the ldap_bind PHP call without username & password, so it is an anonymous bond. I decided to have a clean install to verify everything was ok, so copied my ldap config files, and reinstall on a clean system. the problem is that now the anonymous bind will not work. I turned on all debugging, and found the entry: ... do_bind: v3 anonymous bind in the log. I'm guessing this means that anonymous bind is enabled, but still my PHP code will not bind. I'm not sure where to start to look for the problem. Could someone please point me in the right direction. I can supply logs and configs once I know where to look and what to send.

merging local and remote attributes
by Hugo Monteiro 22 Feb '11

22 Feb '11

Hello list, I have been trying to use translucent overlay to merge attributes between a remote and a local server (both 2.4.23). From the slapo-translucent man page i read: "Attributes may be specified as both local and remote if desired." and "In any case, both the local and remote entries corresponding to a search result will be merged before being returned to the client." The thing is that if i specify an attribute (objectclass) to be both local and remote, i can only get/search for the local entries. Choosing either separately will work as advertised though. Again, i ask if this is a bug, a subtlety i have missed or this is not supposed to work with objectClass attribute? Please advise, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _

Ipad/iPhone ldap setup

I am having trouble accessing my openldap server over SSL using an iPhone/iPad/iPod Touch using ios 4.2.1. If I check the SSL box in the client setup on the iPhone/iPad/iPod Touch I get an error in the slapd log -- TLS negotiation Failure. With logging level 9 I get TLS accept failure error=-1 id=1. Other clients work fine over SSL/StartTLS. Outlook, addressbook in osX 10.6, jxplorer. I am using openldap 2.4.19-15 on RHEL6 with a comodo wildcard SSL cert. Chris Jackson
