Admin server console and TLS
by Mitja Mihelič 04 Aug '10

04 Aug '10

Hi! I am using the Centos directory server and I have run into a problem with the Admin console. I restored the /etc/dirsrv/admin-serv files form from backup and now I get the following error in my error log file for the Admin server: Wed Aug 04 13:50:15 2010] [notice] [client 127.0.0.1] admserv_host_ip_check: ap_get_remote_host could not resolve 127.0.0.1 [Wed Aug 04 13:50:15 2010] [crit] buildUGInfo(): unable to initialize TLS connection to LDAP host cds.example.com port 2389: 4 [Wed Aug 04 13:50:15 2010] [notice] [client 127.0.0.1] admserv_check_authz(): passing [/admin-serv/authenticate] to the userauth handler [Wed Aug 04 13:50:15 2010] [crit] buildUGInfo(): unable to initialize TLS connection to LDAP host cds.example.com port 2389: 4 There is a server running on the 2389 port, I can connect to it. This is the adm.conf : AdminDomain: example.com sysuser: cds isie: cn=CentOs Administration Server, cn=Server Group, cn=cds.example.com, ou=example.com, o=NetscapeRoot SuiteSpotGroup: cds sysgroup: cds userdn: uid=admin, ou=Administrators, ou=TopologyManagement, o=NetscapeRoot ldapStart: /usr/lib/dirsrv/slapd-cds-config/start-slapd ldapurl: ldap://cds.example.com:2389/o=NetscapeRoot SuiteSpotUserID: cds sie: cn=admin-serv-cds, cn=CentOs Administration Server, cn=Server Group, cn=cds.example.com, ou=example.com, o=NetscapeRoot How can I turn OFF TLS for the Admin console ? I know there must be switch in a config file, but where... I have compared the config files with the ones on the sister machine (replica), and they seem alike to me. (Posted host names and domain names are not actual names.) Rerards, Mitja

Set of Attributes Uniqueness
by A Robinson 04 Aug '10

04 Aug '10

Hello, I'm trying to check that values contained in one than one attribute is unique. A solution exists for other directory servers, but I wondered if it was achievable in 389? Is there an equivalent to the NSUniqueAttrSet plugin -- which appears similar to NSUniqueAttr, but for across multiple attributes? http://docs.sun.com/app/docs/doc/819-4438/gcfeh?l=en&n=1&a=view nsslapd-pluginInitfunc: NSUniqueAttrSet_Init nsslapd-pluginType: preoperation nsslapd-pluginEnabled: on nsslapd-pluginarg0: attributeset=mail,mailalternateaddress,mailequivalentaddress nsslapd-pluginarg1: ugldapbasedn Thanks, A Robinson

Problems with chaining (was: RE: Sanity check for install approach)
by Jonathan Boulle 04 Aug '10

04 Aug '10

I've done a colossal amount of reading and experimentation to remedy the ignorance demonstrated in my last email, so let's start again: I have, in a simple two-node (one supplier, one consumer) setup: - Consumer set up with one local database (replicated from the supplier), + one database link back to the supplier - Suffix dc=example using both of these databases, + replication plugin (with repl_chain_on_update) enabled, + suffix request processing set to "use the databases" (i.e. no referrals) - Database link on the consumer using cn=replication manager,cn=config; an ACI on the supplier of (targetattr = "*")(version 3.0; acl "proxy acl"; allow(proxy) userdn="ldap:///cn=replication manager,cn=config";) So, on a client which is pointed towards the consumer, let's try modify something: [bloggsj@client02 ~]$ ldapmodify -x -ZZ -D uid=bloggsj,ou=people,dc=example -w example dn: uid=bloggsj,ou=People,dc=example changetype: modify replace: title title: Sir modifying entry "uid=bloggsj,ou=People,dc=example" --- On the supplier I see the relevant bind requests (as replication user *and* as the bloggsj user, i.e. successfully proxied), and also that the change succeeds (I turned on some ACL logging): <snip> [30/Jul/2010:17:10:03 +0100] NSACLPlugin - proxied authorization dn is (uid=bloggsj,ou=people,dc=example) [30/Jul/2010:17:10:03 +0100] NSACLPlugin - #### conn=26 op=2 binddn="cn=replication manager,cn=config" [30/Jul/2010:17:10:03 +0100] NSACLPlugin - #### conn=26 op=2 binddn="cn=replication manager,cn=config" <snip> [30/Jul/2010:16:56:27 +0100] NSACLPlugin - conn=20 op=2 (main): Allow write on entry(uid=bloggsj,ou=people,dc=example).attr(title) to proxy (uid=bloggsj,ou=people,dc=example): allowed by aci(51): aciname= "Enable self write for common attributes", acidn="dc=example <snip> Great. Works fine, as expected. But if I try to change the userPassword, for some reason the database link does _not proxy the authorisation_, but instead uses the replication user to try make the change: [bloggsj@client02 ~]$ ldapmodify -x -ZZ -D uid=bloggsj,ou=people,dc=example -w example dn: uid=bloggsj,ou=People,dc=example changetype: modify replace: userPassword userPassword: abc123!@# modifying entry "uid=bloggsj,ou=People,dc=example" ldapmodify: Insufficient access (50) additional info: Insufficient 'write' privilege to the 'userPassword' attribute of entry 'uid=bloggsj,ou=people,dc=example'. --- On the supplier: <snip> [30/Jul/2010:17:08:13 +0100] NSACLPlugin - #### conn=24 op=2 binddn="cn=replication manager,cn=config" <snip> [30/Jul/2010:16:57:09 +0100] NSACLPlugin - conn=21 op=2 (main): Deny write on entry(uid=bloggsj,ou=people,dc=example).attr(userPassword) to cn=replication manager,cn=config: no aci matched the subject by aci(53): aciname= "self", acidn="dc=example" <snip> Why do userPassword changes not proxy? I have tried - enabling/disabling "ACL Plugin" component to chain - enabling/disabling "password policy" component to chain - enabling/disabling various LDAP controls to chain - other attributes (homephone, surname, etc), all of which proxy fine to no avail. Rich (or anyone else :-), do you have any ideas? This really looks like a bug to me - I haven't started poking around in the source yet though. -----Original Message----- From: 389-users-bounces(a)lists.fedoraproject.org [mailto:389-users-bounces@lists.fedoraproject.org] On Behalf Of Jonathan Boulle Sent: 29 July 2010 14:54 To: 'General discussion list for the 389 Directory server project.' Subject: Re: [389-users] Sanity check for install approach On closer examination of the doc, it appears that chaining updates is only possible when using database links. However, as I infer, using database links removes the possibility of replication, because the link would pass any modification back to the remote database. Thus, if you had a consumer configured with a database link back to a supplier, and then set up a replication agreement from the supplier to the consumer, it would be replicating to its own database! Am I understanding this correctly? Is there a way to achieve our desired scenario: where no clients can directly access a read-write supplier (i.e. referrals are disabled, because network access is blocked); but they're still able to change their passwords, because the read-only consumer chains the update request back to a supplier?

Tuning 389 DS
by Juan Asensio Sánchez 04 Aug '10

04 Aug '10

Hi I am trying to tune the performance of the Directory Server. We have increased the memory for the database cache and for each database entry cache. These are the new values: cn=config, cn=ldbm database, cn=plugins, cn=config nsslapd-dbcachesize: 838860800 (~800MB) cn=*,cn=ldbm database, cn=plugins, cn=config nsslapd-cachememsize: 125829120 (~120MB) We have 27 databases, and the servers have 16 GB of RAM, so the server should be able to handle all that memory (800 + 120*27 = 4040MB). But when I go to the monitoring section of the management console, the database cache says the hit ratio is 99% (this is OK according to the documentation, near 100%), but the entry cache is 0%, that is very far for 100% that the documentation recomends (see screenshots attached). Am I confused or the configuration is not correct?

Replication without password
by Prashanth Sundaram 03 Aug '10

03 Aug '10

Hi, Is it possible to have different password store on two ldap servers and also setup replication in M-M or M-S(slave) fashion? In other words can I exclude the userPassword¹ field from being replicated between two servers? We need to have different password for two ldap server but they both will have same user/group data? Thanks, Prashanth

Synching with multiple Windows ADs
by John A. Sullivan III 02 Aug '10

02 Aug '10

Hello, all. I know one can only have one sync agreement with an AD. However, is it possible to have a sync agreement with multiple ADs. We would like to synchronize the top of our tree with our main, multi-tenant AD and then synchronize lower levels of the domains with separate domains controlled by our clients. Thus, the same users and groups are synchronized to two different AD trees. As much as we dearly want this to work, I think it is asking for trouble as the GUID from AD is passed back to LDAP as part of the synchronization. Since these GUIDs will be different for the same user from different AD trees, is this a problem? I know that sounds a bit convoluted so let me give an example. I have a user Joe in LDAP. I synchronize him to MyAD so he is MyAD\Joe. I also synchronize him to TheirAD so he is also TheirAD\Joe. The GUID for MyAD \Joe is different from the GUID for TheirAD\Joe even though it is the same LDAP Joe. Is that a problem? Thanks - John
