(ITS#6844) AIX 6.1 | 7.1 not supported in "configure"
by joshua.taylor＠ubs.com 25 Feb '11

25 Feb '11

Full_Name: Joshua Taylor Version: 2.4.24 OS: AIX 6.1 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (193.134.254.26) the configure script has no support for aix6* or aix7*, resulting in assuming no shared libraries are supported. Simply going in after each reference to "aix5*" and adding, " | aix6* | aix7* " enables shared library support. Also, support for IA64 on aix is no more. I'm not even sure there was ever a version that *actually* ran on IA64 cpus.

Dear We have an problem using $OpenLDAP: slapd 2.4.23 (Nov 22 2010 23:39:34) $#012#011@biber:/build/buildd-openldap_2.4.23-7-i386-mi96UQ/openldap-2.4.23/debian/build/servers/slapd The same issue has been be replicated on 2.4.24 When we analyze the debug logs, the crash is performed each time we see this line : is_entry_objectclass("", "2.16.840.1.113730.3.2.6") no objectClass attribute How can we prevent this crash or fix it ? here it is a piece of logs that detect the crash.

(ITS#6843) Can't slapadd cn=config LDIF with global chaining overlay
by rhafer＠suse.de 24 Feb '11

24 Feb '11

Full_Name: Ralf Haferkamp Version: HEAD OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (89.166.251.8) slapadd-ing the following LDIF (a stripped down slapcat output) fails: ------------------------- dn: cn=config objectClass: olcGlobal cn: config dn: olcDatabase={-1}frontend,cn=config objectClass: olcDatabaseConfig objectClass: olcFrontendConfig olcDatabase: {-1}frontend dn: olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config objectClass: olcOverlayConfig objectClass: olcChainConfig olcOverlay: {0}chain dn: olcDatabase={0}ldap,olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config objectClass: olcChainDatabase objectClass: olcLDAPConfig olcDatabase: {0}ldap dn: olcDatabase={0}config,cn=config objectClass: olcDatabaseConfig olcDatabase: {0}config --------------------------------------- The error message is: slapadd: could not add entry dn="olcDatabase={0}config,cn=config" (line=20): Already exists The problem is the olcChainDatabase Entry. As it appears before the config-database entry config_tool_entry_put() will autocreate an olcDatabase={0}config,cn=config and after that choke up when trying to add the olcDatabase={0}config,cn=config that appears later in the LDIF file. I have a fix for this mostly ready. (Just skipping autocreation of the config-Database if child-entries of the frontendDatabase are added)

But what does the filter *mean* in > a modify op? filter on the target entry before it was modified, or after? Hmm - I was thinking of matching on the *modified attributes* (just their presence, not taking account of value). However, I can see that pre- and post-conditions might matter so: logrecord <operations> prefilter|changefilter|postfilter <LDAP URL> logignore <operations> prefilter|changefilter|postfilter <LDAP URL> ... > a search op? match the search request's filter, or filter on the search base? Both if present. Again, I might restrict the filter to matching on the presence of attributes in the filter rather than their actual value. > a compare op? Whatever works for search should be very close.

(Currently it > does this already, if the server is a single-master replica.) There are all sorts of problems to do with ppolicy and replication... Bypassing accesslog is an interesting idea, but I can see that people who use n-failure-lockout might want the lockout events to be auditable. I wonder if there might be some benefit to giving such control on a per-operation basis. Then ppolicy might be configurable to have some automatic ops logged and others not. It could also be the start of a way to make ppolicy actions rather more global across a replication group (e.g. by putting in the ability to queue some ops for replication back to a master server). > So far you're talking about two different enhancements - the > original poster is trying to exclude a set of searches, and you're > talking about excluding modify ops.

Rather than logbase <operations> <baseDN> how about logfilter <operations> <LDAP URL> where the whole clause may be repeated as many times as needed? The LDAP URL can then specify a search base, a filter, and a list of attributes of interest. Extending this to support both inclusion and exclusion clauses might be harder, as you would then need some way to give them an order of precedence. The case I mentioned before would need a rule of the form 'dont log this op if the only change concerns the atttribute pwdFailureTime'. Perhaps a simple list of rules: logrecord <operations> <LDAP URL> logignore <operations> <LDAP URL> ... and if anything is left at the end of the list then it gets logged. The filters would determine whether a log entry would be made at all, and the attribute lists would determine the content.

Re: (ITS#6833) LDAP hangs on Solaris
by tombolala＠gmx.de 23 Feb '11

23 Feb '11

Hi! Thanx for your reply. We have been able to reproduce the problem on a test system and found out that setting "idletimeout" seems to fix this issue for us. Note that we enabled gentlehup! We have now the new configuration on our production environment and everything seems stable. We are not able to change solaris versions. If there are still problems we will upgrade the openldap version. On another system we have the same ldap configuration (gentlehup and no idletimeout set) and do not experience any problem.

Yes... But what does the filter *mean* in a modify op? filter on the target entry before it was modified, or after? a search op? match the search request's filter, or filter on the search base? a compare op? -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

A URI-based restriction specification could include/exclude based on suffix, filter and listed attributes with a unified syntax. p.

Perhaps in that case, it would be simpler just to set ppolicy's mods to be internal-only and bypass the accesslog overlay. (Currently it does this already, if the server is a single-master replica.) So far you're talking about two different enhancements - the original poster is trying to exclude a set of searches, and you're talking about excluding modify ops.
