I don't have #5 (sleepycat#14657) nor the unofficial http://www.stanford.edu/services/directory/openldap/configuration/patches/d… patch. As for the official one, I'm not sure about its relevance to the actual SEGV due to the "recovery...fail" comment. In other words, though it may be impacting the ability of alock/db_recover to do its thing, that's just a side effect of the unclean shutdown which is the real bug here to my view. The region size patch is interesting, but I will tell you that the database in question has set_cachesize 0 200000000 0 and it (to a glance) looks like that only impacts the gig column, which I have as zero anyway. I can tell you that stop/starts weren't an issue with 2.3.32 and the same Sleepycat binaries...not that I stop/start often as a rule of thumb. (I am lately; we're implementing ando's {RADIUS} module.) But two identical traces on two different boxes caught my eye.

This seems to be a known limitation, see the FIXME in slapd/compare.c, near SLAP_COMPARE_IN_FRONTEND. At least, that explains the problem for back-ldif, which does not provide its own compare entry point. As for back-ldbm, there is a missing referral_rewrite call in back-ldbm/referral.c. I don't consider it worthwhile to fix back-ldbm, but you're welcome to fix it if you wish. Just have a look at back-bdb/referral.c for the correct code. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Another scenario is with some tool providing a config file for slapd. It wouldn't have to guess the host arch whether it's i386 or x86_64 and set the correct module_path (/usr/lib/openldap vs /usr/lib64/openldap).

(ITS#4936) default modulepath
by abartlet＠samba.org 23 Apr '07

23 Apr '07

Full_Name: Andrew Bartlett Version: devel OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (66.70.73.150) It would be very useful if OpenLDAP would provide a default value for modulepath. This would ensure that on systems with multiple openldap installs (such as test rigs) that we do not need to specify the *correct* modulepath, when starting the config with different slapd binaries. Similarly, it would avoid the need to guess which modulepath is correct for a given system, such as when we find slapd in the path (as Samba4's test mode does), but needs to automatically enable modules.

(ITS#4935) SASL_MAX_BUFF_SIZE is too small
by lukeh＠novell.com 23 Apr '07

23 Apr '07

Full_Name: Luke Howard Version: 2.3.32 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (125.16.129.17) SASL_MAX_BUFF_SIZE is too small for SASL mechanisms, such as GSS-SPNEGO, that use a buffer size unconstrained by the 64K limit defined for some mechanisms in RFC 2222. A more reasonable default would 0xFFFFFF (2^24), used as the maximum buffer size by many of the mechanisms shipped with Cyrus itself.

(ITS#4934) Port change

Full_Name: Babu Version: 2.3 OS: RedHAT3 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (198.181.8.254) My openldap was running on default port 389 and imported all schema & data. Now I would like to change the port to different..would be 4000/5000. OpenLDAP process started successfully with non default port but I am getting "error 32 no such object" when try to browse the data using soferra. is it possible to change the port anytime? thank you
