slappasswd question
by Greg Martin 01 Jan '07

01 Jan '07

I have slapd configured with password-hash {SSHA}. I'm uusing slappasswd to generate passwords and notice that if I run it twice with the same secret that I get different results. I guess I don't understand this, but how does slapd verify a password if each time I generate it I get something different? Confused! \\Greg $OpenLDAP: slapd 2.3.27 (Oct 13 2006 09:16:43)

Question about DB_CONFIG (set_lg_bsize)
by TechnoSophos 29 Dec '06

29 Dec '06

If my directory routinely stores large chunks of data (like images) that are over two megs in size, should I raise the value for set_lg_bsize to reflect the max size of these files? Matt

Setting dbnosync: do I need to set a checkpoint?
by TechnoSophos 29 Dec '06

29 Dec '06

Using an HDB backend, if I set the dbnosync parameter in slapd.conf, how often will modifications be flushed to the underlying database? I did not find the Berkeley DB documentation to be terribly helpful in this case. It mentions that more frequent checkpointing can help: (http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/env_set…) Should I be using the checkpoint parameter in slapd.conf? I was under the impression (based on threads I have seen in other mailing lists) that checkpoint didn't actually do anything anymore. (And I have not had much luck with using txn_checkpoint in the DB_CONFIG file -- it produces errors). I'm not asking for troubleshooting help on fixing checkpointing. I just want to know how risky it is to use dbnosync, and if checkpointing can help minimize risks. Matt

cetificate issue with ldaps
by jerrrry＠voila.fr 29 Dec '06

29 Dec '06

Hi, i'm using openldap as a ldap proxy to an an other ldap server. I'd like to get a ldaps connexion between this 2 servers. so, i configured ldap.conf like this: TLS_CACERT /usr/local/etc/raddb/RTFE/conca.pem TLS_REQCERT demand My issue is that the ssl connexion still works if i comment the line with TLS_CACERT /usr/local/etc/raddb/RTFE/conca.pem. and it should not because without this certificate authority my openldap proxy should not be able to check the certificate sent by the backend ldap. the only difference that i see without this line is in debug mode (slapd -d 1): TLS certificate verification: Error, self signed certificate in certificate chain but it works with this error. so, do you have an idea to force the ssl connexion to fail if the certificate sent by the other ldap server is not signed by my certificate authority ? Thanks, Thomas

Slapd fails to terminate
by Lesley Walker 28 Dec '06

28 Dec '06

Running 2.3.31, I'm seeing the behaviour described in ITS4790, in which Pierangelo Masarati wrote: >> Apparently, one thread is unable to terminate correctly... >> but then slapd hangs forever in ldap_pvt_thread_pool_destroy(). and Howard responded: > This is a bad patch to connections_shutdown in RE23, there is a > "continue" after checking for a client session that shouldn't be > there. This line is not present in HEAD and the bug doesn't exist > in HEAD. Strange that it got there since we just recently sync'd > RE23 with HEAD's connection.c. Ok, so the problem line is in connection.c, right? I know just about enough C to be able to comment out the line. How do I identify it? I need to fix this pronto, as I have already rolled out the bad code to about half of our ~80 replicas.
