(ITS#6605) Webmin LDAP User Module Don't Work
by andrea.minardi＠port.ravenna.it 27 Jul '10

27 Jul '10

Full_Name: Andrea Minardi Version: 2.3.27 OS: RedHat 5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (88.40.179.242) Webmin's LDAP Users and Groups module stopped working after upgrading from Webmin 1.400 to webmin 1.510 I have been using Webmin's LDAP Users and Groups module on my company's server to administer users. It was working fine on Webmin 1.400, but after upgrading I get the error: "Webmin has connected to the LDAP server, but failed to fetch the schema. Make sure that access has not been denied in the LDAP Server module."

(ITS#6603) EAGAIN, EWOULDBLOCK occasionally used without checking #ifdef
by masarati＠aero.polimi.it 27 Jul '10

27 Jul '10

Full_Name: Pierangelo Masarati Version: irrelevant OS: irrelevant URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (129.72.165.243) Submitted by: ando At least in libldap and liblber EAGAIN and EWOULDBLOCK are occasionally used without checking whether they are defined or not. Either the checks should be removed, counting on the fact that these error codes are always defined, or they should be used consistently.

Yours looks like a good catch; however, your patch looks a bit like an overkill, since the an_desc field of the attribute list that is passed to get_attr_set() should already be set if the attribute was recognized by slapd, so you don't need to go through slap_bv2ad() once more. p.

Which is nice, but doesn't help with older debian versions. I don't see what's wrong with changing our #elif to #elif defined like you originally suggested, though I remember there was some confused #elif discussion earlier. -- Hallvard

(ITS#6600) pcache overlay should ignore invalid attributes in search requests
by jonathan＠phillipoux.net 23 Jul '10

23 Jul '10

Full_Name: Jonathan CLARKE Version: RE24 OS: URL: ftp://ftp.openldap.org/incoming/jonathan-clarke-pcache-100723.patch Submission from: (NULL) (80.13.86.63) While checking it's configuration, the pcache overlay verifies each configured attribute set (pcacheAttrset), to ensure that all attributes in the set are defined, via slap_str2ad. Given an attribute set with a non-existant attribute, an error is logged and slapd refuses to start (as expected): line 117 (pcacheAttrset 0 nonexistantAttr) /etc/ldap/slapd.conf: line 117: attribute type undefined. However, when a search request comes in, the requested attributes list is not checked by the pcache overlay to ensure that attributes are properly defined. In effect, slapd just ignores the non-existant attributes, and returns other attributes (or behaves as if 1.1 was requested if all requested attributes are invalid). This causes pcache's attribute set matching to fail for some requests, since it counts invalid attributes. If it were to ignore them, configured attribute sets might match, and successfully cache the search. The patch above implements this behaviour. Would you consider it for inclusion in OpenLDAP? I realize this may be considered "repairing bad requests", but sometimes one can't (easily) control what clients are requesting. Furthermore, it seems to make sense to have matching behavior all over (since slapd ignores invalid requested attributes, pcache should too, IMHO).

(ITS#6599) slapd not responding
by binoy＠cordys.com 23 Jul '10

23 Jul '10

Full_Name: Binoy Joseph Version: 2.4.21 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (210.210.79.19) I run OpenLDAP 2.4.21 configured to bdb on Windows and Linux. We run some applications on top of our application framework which in turn is connected to OpenLDAP via JLDAP. We list children of 'cn=soap nodes' (search LDAP) very often as shown in the DIT below. I wrote a test case to create soapnode, soapproc, connectionpoint and then delete them one after the other, ie I create set1, delete set1, create set2, delete set2... Note that list children of 'cn=soap nodes' happen in parallel as mentioned above. Randomly but very consistently, suddenly we face an LDAP not responding issue. When I connect via an LDAP Explorer, I am able to see and expand most of the LDAP entries, except the 'cn=soap nodes' as shown in the DIT below, which says LDAP query did not return indefinitely. CPU: slapd shoots to 50% in Windows and 100% in Linux. Then I have to kill slapd and start again. This does not happen in OpenLDAP 2.4.16. After upgrading to 2.4.21 this started happening. When I switched to hdb, this does not occur in Linux, but continues to happen in Windows. This also looks very similar to http://www.openldap.org/its/index.cgi?findid=6322, Subject: slapd suddenly stops working, and starts using 100% CPU. o=org1 | +-cn=soap nodes | +-cn=soapnode1 | | | +cn=soapproc1 | | | +cn=connectionpoint1 | +-cn=soapnode2 . . Thanks and regards, Binoy Joseph
