a problem with centralized authentication using openLDAP
by Tamer Al-Khouli 20 Mar '08

20 Mar '08

Hi everyone, I am trying to set up and openLDAP server for centralized authentication. I used self-signed certificate and put the generated server.pem file in the slapd.conf, then i checked it using the following command: $openssl s_client -connect localhost:636 -showcerts and i got : Verify return code: 18 (self signed certificate) which, as i read, indicates that things fine with the server. Next, i tired: $ldapsearch -x "uid=user1" and i got : ============ # extended LDIF # # LDAPv3 # base <> with scope subtree # filter: uid=user1 # requesting: ALL # # search result search: 2 result: 0 Success # numResponses: 1 ============= Even though there's an entry with that uid, so i ran slapd in the debug mode 9 using this command: $/usr/sbin/slapd -d9 -h "ldap:/// ldaps:///" 1>/var/log/ldaplog 2>&1 and i did the ldapsearch again and got this from the log: ========================== TLS trace:SSL_accept:error in SSLv3 read client certificate A .... commection_read(14): unable to get TLS client DN, error=49 id=6 .... connection_read(14): input error=-2 id=6, closing. ========================== I thought the error seen in the log could be related to the fact that i didn't do anything on the client side to give it a certificate, so i assigned the same server.pem file to the client in the /etc/openldap/ldap.conf file as follows: .... TLS_CACERT /etc/openldap/server.pem TLS_REQCERT allow .... and issued the ldapsearch command again, and i got this: ldap_bind: Can't contact LDAP server (-1) additional info: TLS: hostname does not match CN in peer certificate. I am stuck here and don't know what to do, can any one help, please ?!

Problems creating a Samba4 LDAP Backend
by Andrew Bartlett 20 Mar '08

20 Mar '08

Over the past few weeks, I have been testing OpenLDAP as a backend for Samba4. I've been working with the OpenLDAP team on my requirements, and there has been some really good outcomes - the memberOf module has been improved, as has the refint module. However, I seem to have hit a brick wall, in the form of (internal) transaction support. I need an LDAP backend to support internal transactions - that is, when for example a 'member' modification is made, all the memberOf attributes must be updated before the call returns. Similarly, if a user or group moves, all the member/memberOf attributes that link the user to their groups must also move, before the modrdn returns. The Samba4 test ldap.js tests this behaviour extensively, because I want to be sure it works. As understand the discussion I've had with the OpenLDAP team, OpenLDAP does not support this, and will not support it for perhaps some time. Similarly, from discussions with the Fedora DS team at the CIFS developer days, I understand that it is similarly very unlikely that Fedora DS will support internal transactions. (It also does not support subtree renames, which we also need). The fact that LDAP does not expose a transaction API was always going to be a difficult part of having Samba4 use an LDAP backend, but I always assumed that if we pushed the really hard bit - updating linked attributes - into the LDAP server that we could at least always have a consistent DB. (It turns out this is one of the primary uses of transactions anyway.) But without that consistency, and without knowing as a caller if all the updates succeed, I'm worried about how we can safely move forward. This is especially disappointing because I was hoping that these free, replicating LDAP servers might solve the backed replication problem for me, without needing to use AD replication. Does anybody have any ideas or suggestions on how I could get around this? Should we drop the LDAP backend as a nice idea, but not going to work, and focus on DRS or some other form of replication? Can someone imagine a sane way to reconstruct the DN links, including subtree renames, without the help of the LDAP backend? Could we ban subtree renames (as Fedora DS does), and try to handle this ourselves (with pre/post checks and a good deal of prayer)?

Loading the refint module globally?
by Andrew Bartlett 17 Mar '08

17 Mar '08

I've been wondering why I couldn't get the wonders of refint and memberOf to play together, and even went to the extent of writing a testsuite to prove that they could work (indeed, they do). However, I eventually found my problem - while memberOf works very nicely as a global overlay, the refint module does not (yet :-). With it loaded per-backend (for now), it seems to work. Any chance someone could knock me up a patch for that, much like was done so well for memberOf?

proxycache examples
by Andy Cobaugh 15 Mar '08

15 Mar '08

I'm working in an environment where the server I wish to use for user and group lookups (through nss_ldap on RHEL) limits the number of queries per IP per day to 200. I want to cache as much as I can locally, for as long as I can. This data hardly ever changes, so the longer I can cache, the better. I'm thinking of caching everything for at least a day, if not longer. Does the pcache overlay currently support such long ttl's? Does anyone have any working pcache configs that can be used to cache the kind of searches performed by nss_ldap ? -- Andy Cobaugh

Changing attribute values on the consumer
by Kyriakos Stefanidis 14 Mar '08

14 Mar '08

Hello all, Is it possible to change the attribute values on the consumer (of the replication scheme) or add new attributes and preserve them during replication? Im using external scripts that refresh the values/attributes regulary but I was wondering if there is another more "elegant" way Best Regards Kyriakos
