ppolicy in openldap
by Allgood, John 19 Jan '09

19 Jan '09

Hello All I am fairly new to openldap and have some questions about password policys. We are running ldap on RHEL5 and using openldap 2.3.27. The ppolicy overlay gives me a lot of what I need but RHEL5 does not seem to have it installed. How can I get this installed? Also the best that I can tell is that ppolicy does not have any dictionary checks either. Is this true or did I just miss something? What I would like to setup is what we currently have in place using cracklib. Minlen=8 at least 1 Uppercase, 1 Lowercase, 1 Number, 1 special char.

openldap group filter and websphere
by hai wu 17 Jan '09

17 Jan '09

Hi, We have one openldap server, and for dev environment, groups are put under 'ou=devgroup,dc=example,dc=com', and for production environment, groups are put under 'ou=group,dc=example,dc=com'. When integrating websphere to openldap, we can only specify one search base, which is set to 'dc=example,dc=com', and for the group filter, it is set to '(&cn=%v)(objectclass=posixGroup))'. But in this case, it is pulling all groups from both dev and production environment. Is there a way to set the group filter so that for our dev environment, it would only pull dev groups, and for production environment, it would only pull production groups? I tried ldapsearch by applying the group filter, modified it a little bit, but still could not get it to work in our case. Thanks, Hai

Does anyone could provide some guide on how to configure the openldap TLS connection with step by step, so can reduce our pain ? Here I expose the step and try to get help from the senior ldap engineer. 1. installed openldap with-tls=openssl I add the openssl specially to avoid use gnutls, sometimes, openldap will goto find gnutls if c header is there install and start slapd succesfully. 2. using ldapsearch -v -h 10.192.183.73 -b "dc=example,dc=com" -s base "objectclass=*" I can get the listed information from openldap server, that is ok 3. now go for certificate genearation with numerous guide in google , but not fit to pass for me 3.1 cd /var/myca /usr/local/ssl/misc/CA.sh -newCA then will generate demoCA, and cacert.pem is there, that is ok 3.2 /usr/local/ssl/misc/CA.sh -newreq newkey.pem newreq.pem notes : I am using 10.192.183.73 as the common name, is there any issue here? 3.3 /usr/local/ssl/misc/CA.sh -sign then you got newcert.pem now copy into /var/ldap and try to insert into slapd and restart TLSCipherSuite MEDIUM:+TLSv1+SSL3+SSL2 TLSCertificateFile /var/ldap/newcert.pem TLSCertificateKeyFile /var/ldap/newkey.pem ( some guide said should be newreq.pem) TLSCACertificateFile /var/ldap/cacert.pem 4. ftp cacert.pem into client and copy into /var/myca using s-client to test at first penssl s_client -connect 10.192.183.73:389 -showcerts -state -CAfile /var/myca/cacert.pem -tls1 you will got the error always CONNECTED(00000003) SSL_connect:before/connect initialization SSL_connect:SSLv3 write client hello A SSL_connect:failed in SSLv3 read server hello A 14719:error:1409E0E5:SSL routines:SSL3_WRITE_BYTES:ssl handshake failure:s3_pkt.c:530: could any kind man to give some help to save me? -- Hunter

Build it how you like, it's best to build from source to start with to get a feel for everything. Then depending on how you company works you can move to a commercially supported version. I would never recommend the RHEL version, but please visit the list archives for why. Thanks. -- Kind Regards, Gavin Henry. Managing Director.

Re: Re: N-Way Multi-Master replication - delete problem
by Adrien Futschik 15 Jan '09

15 Jan '09

It seems like I am not the only one facing this problem. Is this officially reported as a bug ? I found out that when deleting an entry on the master I added it to, it is removed only on this master and deleting is not replicated until I make some other operation on the other master. Seems like the delete is "queued". When deleting an entry on the "other" master (not the one I added the entry to), the delete works fine and is correctly replicated. Anyone to help me with N-Way Multi-Master replication ?

Hey All I am working on setting up sync replication for ldap. I have it working but I am not sure exactly what I can do with it. How do I failover to it?

OpenLDAP centralized authentication with Active Directory
by Duong Pham Tung (FIM HN) 13 Jan '09

13 Jan '09

Hello, My company network have some different domains such as abc.net, abc.com and xyz.com (I don't use real domain name because of our company's security policy). Each domain is managed by a dedicated Active Directory server. Now, I want to use one OpenLDAP server to authenticate all users from these domains because we want manage services they use focusly (such as Mail, Portal). But now, I have'nt any solutions to solve this problem. Because the number of users is very large (approximately 10.000 users) so I can't build database by hand. Can anyone suggest me the solution to solve this problem. Thanks and Best regards, Duong Pham.
