Re: (ITS#6900) dnattr acl statement: users can produce dangling entries
by daniel＠pluta.biz 24 Apr '11

Hopefully nobody else than me has wasted his/her time reviewing my previously submitted patches related to this ITS. They are completely wrong! Here you'll find a rewritten version from scratch which should work as expected or at least can be taken as a basis for further reviewing: ftp://ftp.openldap.org/incoming/Daniel-Pluta-110424-2.patch

Maybe it was always a problem. Because I've started the thread above before installing 2.4.25: http://www.openldap.org/lists/openldap-technical/201103/msg00032.html I had 2.4.24 or 2.4.23 installed back then. > This may be related to ITS#6766. Seems similar and the group modification is the same like in cases where I observed the behaviour described in my postings. Ciao, Michael.

(ITS#6915) memberof+accesslog duplicate reqStart
by ebackes＠symas.com 23 Apr '11

23 Apr '11

Full_Name: Emily Backes Version: 2.4.25 OS: any URL: Submission from: (NULL) (76.88.107.46) In recent OpenLDAPs (2.4.25 at least, but I haven't found exactly where it started), memberof interacts badly with accesslog. In a simple test case with a groupOfNames and two people, if you add a person to the group, memberOf should set their memberOf opeational attribute to point to the group. That works! But currently the accesslog db will only show the change for the memberof update and not the original group change. Digging deeper, I found: ==> hdb_add: reqStart=20110422103943.000001Z,cn=log oc_check_required entry (reqStart=20110422103943.000001Z,cn=log), objectClass "auditModify" oc_check_allowed type "objectClass" oc_check_allowed type "structuralObjectClass" oc_check_allowed type "reqStart" oc_check_allowed type "reqEnd" oc_check_allowed type "reqType" oc_check_allowed type "reqSession" oc_check_allowed type "reqAuthzID" oc_check_allowed type "reqDN" oc_check_allowed type "reqResult" oc_check_allowed type "reqMod" bdb_dn2entry("reqStart=20110422103943.000001Z,cn=log") send_ldap_result: conn=1000 op=1 p=3 send_ldap_result: err=68 matched="" text="" The changes are reaching accesslog, but don't make it into the logdb because their generated DNs based on reqStart match. reqStart is generated with a generalizedTime stamp where the microseconds are an incrementing count based on o_tincr, but this does not seem to be incremented, or incremented enough. It's not entirely clear why this is a problem now and not earlier. This may be related to ITS#6766.

(ITS#6914) Feature Request: slapd.conf "include" extension
by marco.pizzoli＠gmail.com 23 Apr '11

23 Apr '11

Full_Name: Marco Pizzoli Version: 2.4.x OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (217.133.1.151) Hi, this is a feature request. I would like to extend "include" directive of slapd.conf by having defined a default path in witch beginning to search for the filename specified by "include" directive(s). In short I would like to mimic the behaviour of "modulepath" and "moduleload" directives. "includepath" could be a suggestion of the name of this new directive. Thanks Marco

Re: (ITS#6900) dnattr acl statement: users can produce dangling entries
by daniel＠pluta.biz 21 Apr '11

Once again an update of this patch: One more step further dnattr's documented behaviour: Now the DN in dnattr is additionally allowed to remove the whole entry. The update can be found here: ftp://ftp.openldap.org/incoming/Daniel-Pluta-110422.patch I'm not quite satisfied with my code and its internal processing. It's more some kind of a prototype. Probably you guys do have the knowlege to "convert" it into a better and slapd-like design... Thanks a lot!

I tried to find the magic flag where to put SLAP_AT_MANAGEABLE but failed. It must be something emotional with C code on my side... ;-) Ciao, Michael.
