Are we any further forward to getting this rolled into contrib? Is there more we need to do to make it fit better? The tarball has been sitting there a while, it would seem.

"error in SSLv3 flush data" when connecting from network again!
by Lifeng Wang 26 Feb '09

26 Feb '09

Hi All, After many googling, I find one thread in openldap mailing list year 2007, Feb to March about this issue, but no solution, and now it happened to me again. So I'm write to this mailing list to report this bug. I'm running openldap 2.3.27 on CentOS 5.2 x86_64. I configured TLS on the server, and localhost successfully connected to 389 port with start_tls. However when I try to connect to this ldap server with start_tls from a Fedora 10 x86_64 client, it hangs. As previous reported, if I launch slapd with -d2, remote client can connect to the server with TLS. by using -d1 on both server and client, server hangs at some where: TLS trace: SSL_accept:error in SSLv3 write certificate request B and client hangs at TLS trace: SSL_accept:SSLv3 read certificate A So, I rung -d2 on client, and find: tls_read: want=179, got=179 ... tls_read: want=5, got=5 ... tls_read: want=14771, got=9952 ... So, the last seconds shows client expecting 14771 bytes of data, but server only send 9952 bytes, so client thinking server will send more, but server get error? if I run same ldapsearch command from server (localhost), that line read as: tls_read: want=14771, got=14771 Does this ring the bell? Thanks Noodle

(ITS#5978) Addition to syncrepl Documentation in Administrater's Guide

Full_Name: Matthew Roy Version: 2.4.9 OS: Ubuntu URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (209.94.128.99) In the Administrater's Guide, Section 18.3.1.3 (http://www.openldap.org/doc/admin24/replication.html) there is no mention of needing to explicitly load the "syncprov" module with a loadmodule directive. It is mentioned when talking about Delta-syncrepl in 18.3.2, but is not previously in 18.3.1 when setting up "plain" syncrepl between servers. Simply adding it to the example server configuration so new users realize that this module may need to be loaded would be sufficient. Otherwise, we try the sample code and the testing server won't start and needs to be debugged. Sure it's not a big deal, but first experiences should be as positive as possible.

OK, I was working on a fix that always eliminated duplicates, but yours is saving the effort when not strictly needed. p. Ing.

After value normalization, slapd-ldap I think should also check for duplicates (possibly leaving this as an option), and discard them. In fact, it is the proxy backend that injects broken data into the loop. Of course, the best solution in your case would probably be to fix your data... :) p. Ing.

(ITS#5977) pcache and broken Active Directory equality matching rules

Full_Name: Matthew Hardin Version: 2.4.14 OS: RHEL4 x86 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (74.44.226.116) Given an Active Directory group object containing the following two members: member: cn=Frank Y. Ewe,ou=Important Accounts,ou=User Accounts,ou=Common,dc=ad,dc=foobar,dc=com and member: cn=Frank Y. Ewe,ou=Important Accounts,ou=User Accounts,ou=Common,dc=ad,dc=foobar,dc=com (note the extra space between "Frank" and "Y" in the second member) Active Directory sees these as different entries and allows them to both be members of the same group. Back-LDAP and back-meta happily return both of these values. When 'sortvals member' is turned on, the pcache overlay will cache this value but will not return it on subsequent searches because it sees these two values as duplicates. According to Howard Chu, this is because the equality matching rule for the 'member' attribute collapses multiple spaces into one before doing the comparison and so reports these two values as duplicates. Howard asked me to file this ITS as a means to solicit guidance from others as to the best way/place to fix this. Comments? -Matt

Re: (ITS#5975) minor issue with slapd.conf manpage

But the existence of the pidfile also means one need not save the pid after running slapd &. So I think it's best to keep the existing behavior, in case someone depends on the pidfile. -- Hallvard
