Extend slapd -c option to accept only sid=XXX?
by Rein Tollevik 09 Mar '09

09 Mar '09

There are (at least as far as I know) no other way than slapcat/slapadd to get rid of any incorrect contextCSN values, at least on servers where syncprov is enabled. I have been down that road some times already, each time being equally annoyed by the fact that there are no easier way to fix it.. Removing a contextCSN value is required in order to remove a server from a multi-master configuration, or to get rid of the values with SID=0 that is far to easy to slip in if slapd or slapadd is started without the proper serverID setting. The slapd -c option requires a rid=XXX to be specified, but also allows sid=XXX (which I haven't quite understood the usefulness of..). I suggest that the -c option is extended to also allow only sid=XXX without any rid. With only sid=XXX,csn=XXX specified both syncrepl and syncprov should replace the contextCSN value with that sid (as read from the database upon startup) with the specified csn. Obviously, only a single csn value can be accepted, and an absent or zero csn value should mean to delete the contextCSN value with that sid. Well, deleting a contextCSN value is really all I need, so I would be I more than happy to leave the replace possibility out... Adding an easy way to get rid of invalid contextCSN values should make a transition to enforcing serverID 0 for single-master only configs much more acceptable for those that have used serverID 0 in multi-master setups. Comments? Rein

multiple free in ldapsearch

Hello NetBSD's libc reports a multiple free each time I run 2.4.15's ldapsearch using x509 certificate authentication (That is, SASL EXTERNAL): Running with export MALLOC_OPTIONS=A, it is kind enough to abort, so I have a backtrace: (gdb) bt #0 0xbb94223f in kill () from /usr/lib/libc.so.12 #1 0xbb9dea64 in abort () from /usr/lib/libc.so.12 #2 0xbb9dd300 in tcgetattr () from /usr/lib/libc.so.12 #3 0xbb9dd331 in tcgetattr () from /usr/lib/libc.so.12 #4 0xbb9de661 in free () from /usr/lib/libc.so.12 #5 0xbbaff5c7 in CRYPTO_free () from /usr/lib/libcrypto.so.3 #6 0xbbad0871 in X509_asn1_meth () from /usr/lib/libcrypto.so.3 #7 0xbbaec6d7 in ASN1_primitive_free () from /usr/lib/libcrypto.so.3 #8 0xbbaec8f3 in ASN1_item_free () from /usr/lib/libcrypto.so.3 #9 0xbbad09dd in X509_free () from /usr/lib/libcrypto.so.3 #10 0xbbb6fe31 in ssl_cert_free () from /usr/lib/libssl.so.4 #11 0xbbb6d981 in SSL_CTX_free () from /usr/lib/libssl.so.4 #12 0xbbbe008f in tlso_ctx_free () from /usr/pkg/lib/libldap-2.4.so.2 #13 0xbbbdce5b in ldap_pvt_tls_ctx_free () from /usr/pkg/lib/libldap-2.4.so.2 #14 0xbbbdcf78 in ldap_int_tls_destroy () from /usr/pkg/lib/libldap-2.4.so.2 #15 0xbbbdd06e in ldap_pvt_tls_destroy () from /usr/pkg/lib/libldap-2.4.so.2 #16 0x08050e88 in ??

See ITS#5454 and the commit logs for this history behind this one, it's gone back and forth several times. The recent change to add a 4th server to test050 caused a config/pause deadlock to occur again. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

N-Way docs

Hi All, I know they suck, they were just meant to have something there. What we would we like to see using the slapd-config format? A simple example that can just be used with ldapadd/slapadd in one go? Thanks. -- Kind Regards, Gavin Henry. Managing Director.

It's not right or finished. Can someone check if I'm on the right path though? I know each master must be pointed to itself and the other masters, but I didn't want to make it really cluttered. What's the standard and best way to represent what we can do with our N-Way? Star topology first? This is going in my presentation, so I though it would be a good time to do it for our docs too: http://www.ukuug.org/events/spring2009/programme/openldap-replication.shtml Thanks. P.S. If you'd like a copy for the "Other Publications": http://www.openldap.org/pub/ I would be happy to provide any format, but not sure if only core team members are allowed to list their presentations there.
