14 Jun '12

Full_Name: SATOH Fumiyasu Version: master, 2.4.31 OS: URL: https://gist.github.com/2931574 Submission from: (NULL) (114.48.132.80) In contrib/slapd-modules, some modules have no Makefile to build and install itself. I've created a patch to add Makefile and update README for that.

You are making assumptions regarding how junk is actually defined. The = server should not make any assumptions. Also, even if junk was defined in the client's schema: ( 1.1.1.1 NAME ( 'junk' 'crap' ) AUXILIARY MUST objectClass ) and the server could easily have in its schema: ( 1.1.1.1 NAME 'crap' AUXILIARY MUST objectClass ) in its schema and lots of entries belonging to this class. The server cannot possibly return any of these entries when the filter = is (objectClass=3Djunk) and shouldn't return any entries when the filter = is (!(objectClass=3Djunk)), because doing so is, per the specs, wrong. The specs say that such filters should evaluate to Undefined. That's = what slapd(8) does. >=20 > --Quanah >=20 >=20 > -- >=20 > Quanah Gibson-Mount > Sr. Member of Technical Staff > Zimbra, Inc > A Division of VMware, Inc. > -------------------- > Zimbra :: the leader in open source messaging and collaboration >=20 >=20 --Apple-Mail=_9109C66A-11FD-46D5-B12C-CDB17F336920 Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=us-ascii <html><head></head><body style=3D"word-wrap: break-word; = -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; = "><br><div><div>On Jun 14, 2012, at 3:31 PM, <a = href=3D"mailto:quanah@zimbra.com">quanah(a)zimbra.com</a> wrote:</div><br = class=3D"Apple-interchange-newline"><blockquote type=3D"cite"><div>--On = Thursday, June 14, 2012 3:09 PM -0700 Kurt Zeilenga <br><<a = href=3D"mailto:Kurt@OpenLDAP.org">Kurt(a)OpenLDAP.org</a>> = wrote:<br><br><blockquote type=3D"cite"><br></blockquote><blockquote = type=3D"cite">On Jun 14, 2012, at 2:10 PM, <a = href=3D"mailto:quanah@openldap.org">quanah(a)openldap.org</a> = wrote:<br></blockquote><blockquote = type=3D"cite"><br></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite">Full_Name: Quanah = Gibson-Mount<br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote type=3D"cite">Version: = 2.4.31<br></blockquote></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite">OS: Linux 2.6<br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote type=3D"cite">URL: <a = href=3D"ftp://ftp.openldap.org/incoming/">ftp://ftp.openldap.org/incoming/= </a><br></blockquote></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite">Submission from: (NULL) = (75.108.184.39)<br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote = type=3D"cite"><br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote = type=3D"cite"><br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote type=3D"cite">Handling "!" with objectClasses = appears to be broken.  For example, if = I<br></blockquote></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite">perform the following ldap = query:<br></blockquote></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite"><br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote type=3D"cite">zimbra@zre-ldap002:~$ ldapsearch = -LLL -x -H <a href=3D"ldapi:///">ldapi:///</a> -D cn=3Dconfig = -w<br></blockquote></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite">zimbra -b "" = '(!(objectclass=3Djunk))'<br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote = type=3D"cite">zimbra@zre-ldap002:~$<br></blockquote></blockquote><blockquo= te type=3D"cite"><blockquote = type=3D"cite"><br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote type=3D"cite">This result appears incorrect to = me.  I would expect it to return = all<br></blockquote></blockquote><blockquote type=3D"cite"><blockquote = type=3D"cite">entries without that objectClass (which in this case, = would be every<br></blockquote></blockquote><blockquote = type=3D"cite"><blockquote = type=3D"cite">entry).<br></blockquote></blockquote><blockquote = type=3D"cite"><br></blockquote><blockquote type=3D"cite">which object = class (by OID)?

Well, I would note that AD at least behaves the way in which I expect. Just because the objectClass doesn't exist in the schema, I don't think it should fail to evaluate. Clearly, if none of the objects match the filter, it should return them. --Quanah -- Quanah Gibson-Mount Sr. Member of Technical Staff Zimbra, Inc A Division of VMware, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration

Full_Name: Quanah Gibson-Mount Version: 2.4.31 OS: Linux 2.6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.108.184.39) Handling "!" with objectClasses appears to be broken. For example, if I perform the following ldap query: zimbra@zre-ldap002:~$ ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra -b "" '(!(objectclass=junk))' zimbra@zre-ldap002:~$ This result appears incorrect to me. I would expect it to return all entries without that objectClass (which in this case, would be every entry). Doing the same sort of search on a different attribute, the behavior is as expected: ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra -b "" '(!(mail=junk))' [snip] # search result search: 2 result: 0 Success # numResponses: 82 # numEntries: 81

Given the fact that there's no standard with appropriate security considerations clearly saying e.g. what should be done in case of StartTLS and hostname check I would also leave it up to the application to do the DNS lookup itself. I think people asking for including that feature into libldap should first try to implement it themselves taking into account all security implications when relying on DNS. Several existing approaches are IMO flawed. Ciao, Michael.
