Any success story using syncRepl with postgresql backend?
by Tommy Ho 12 May '08

12 May '08

I was wondering if anyone had success with using multi-master replication (syncrepl with mirrormode enabled) using postgresql as the backend? I had this working using BDB but when I switched over to use postgres as the backend, the synchronization becomes very erratic and inconsistent, deleted data from one master never gets propagated and newly added data will sometimes get sync'd and sometimes it doesn't. Thanks for any input, \Tommy

DHCP breaks LDAP?
by John Oliver 12 May '08

12 May '08

On two RHEL4u5 lab machines, LDAP authentication stopped working. The only thing that was done was DHCP was enabled on a previously-unconfigured interface. That messed up ntpd.conf, so I know that weird stuff was going on. Anyway, all attempts to log in with an LDAP user result in ldap_simple_bind: Can't contact LDAP server However, the machines can ping the LDAP server, and nmap shows 389 and 636 as open. /etc/ldap.conf has not changed. /etc/nsswitch.conf has not changed. I ran "authconfig" and the server line was empty, so I filled it in. No dice. I am completely stumped. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Mystery - Authentication Would Fail If Not Binding With Server By Using cn=Manager
by Luke Lee 10 May '08

10 May '08

I am running OpenLDAP 2.3.39 on RedHat. My login authentication on a client system will fail if I don't configure the optional binddn and bindpw by using cn=Manager. Can anyone please enlighten me what could cause the strange problem? Thanks!

migration question
by Gordon 10 May '08

10 May '08

Our users have Thunderbird configured to search for email addressed in ldap our old ldap has a base DN of dc=sbg,dc=com our new ldap has a base DN of ou=people,dc=sbg,dc=com Is there a way to provide a view or alias of the new system so clients do not have to be updated to the new base DN?

AD + Openldap integration
by Rich West 08 May '08

08 May '08

I am not entirely sure where to ask this particular question, and I apologize in advance if this is not the correct forum... We have an AD infrastructure and we'd like to get all of our unix boxes to authenticate against the AD servers. I'm able to query against our AD servers by hand using: ldapsearch -x -LLL -E pr=200/noprompt -h ouradhost -D "CN=Administrator,OU=IT Department,OU=Users,OU=My Business,DC=ourdomain,DC=dotcom" -W -b "dc=ourdomain, dc=dotcom" -s sub "(cn=*)" And that gives me the entire tree, but I haven't made much progress from there. Honestly, I am unsure what 'right' resulting architecture would be: have each unix (linux, CentOS) system, using nss_ldap, authenticate against AD directly, or build an openldap replica of the AD contents (just user accounts) and have the unix boxes authenticate against that. Because of the AD layout, I'm not sure nss_ldap is even configurable enough to map users from the mess of groups within AD to one layer of users. The AD layout is messy.. the users are broken up in to different groups ("IT Department", "Executives", etc., etc) within AD, and it isn't straightforward on how to do a query just to get all users (regardless of the group). (unfortunately, I have no ability at this time to re-work the AD architecture, nor do I take responsibility for its current layout) Thanks! -Rich
