This is a multi-part message in MIME format. --------------020600000809090503050207 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Riight - I see what you mean now. I mis-read the debugging messages as meaning it had reconnected without TLS. Retesting with a sniffer shows otherwise. So "-Z" works as I had hoped - excellent Thanks!

Actually, ldapsearch(1) does not fall back into cleartext in this case.  The OpenLDAP library, and most servers, wisely don't support stop TLS.

No, it's not.  If you continued to use TLS, there is no server authentication.  Use of cleartext mechanism to an unauthenticated server is quite insecure.

(ITS#7045) "ldapsearch -Z" should continue using TLS one cert mis-match
by Jason_Haar＠trimble.com 18 Sep '11

18 Sep '11

Full_Name: Jason Haar Version: 2.4.21 OS: Fedora URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (222.154.246.214) As you know, LDAP passwords are sent in cleartext unless TLS or SASL are used. However, "ldapsearch -Z" will fall-back onto cleartext if any form of TLS error occurs, even the non-fatal "TLS: hostname does not match CN in peer certificate" error. i.e. TLS is attempted, the hostname doesn't match, so ldapsearch tries again not using TLS! This seems wasteful to me. It is still *more secure* to continue the encrypted TLS session than to fallback onto cleartext. Web browsers are a good example of this: if you connect to a self-signed https site, you can choose to continue - as untrusted https is still secured against other attackers. If a user wants to guarantee the trustworthiness of their ldapsearch session, they can use "-ZZ" to achieve that - but I can't see any reason to stop people using "-Z" if they want to? (I'm using ldapsearch to dump Active Directory LDAP data via the DNS round-robin entry for the domain name: as such the LDAP host *never* matches the hostname DNS round-robin gives back - and I don't care - I just don't want the network group sniffing my password ;-)

(ITS#7044) objectIdentifier not usable for reference in objectClass' MUST or MAY clause
by carsten.klein＠axn-software.de 15 Sep '11

15 Sep '11

Full_Name: Carsten Klein Version: 2.4.23 OS: Kubuntu 11.01 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (91.54.26.231) I tried to get rid of the global namespace restrictions regarding attributeType names by declaring objectIdentifierS for each of the attributeTypeS forefront and then use these both for declaring the attributeTypeS and also using them for reference in a MAY or MUST clause in the declared objectClassES While the attributeType declaration works just fine, the objectClassES will not be parsed, resulting in an error stating that the OID cannot be resolved. How to reproduce: objectIdentifier fooOID 1.3.6.1.4.1.123456789 objectIdentifier fooAttrOID fooOID:1 objectIdentifier fooClassOID fooOID:2 attributeType ( fooAttrOID NAME 'fooAttr' SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) objectClass ( fooClassOID NAME 'fooClass' SUP top STRUCTURAL MAY ( fooAttrOID ) ) will not work as expected. However, replacing fooAttrOID in the above objectClass declaration by either fooAttr or 1.3.6.1.4.1.38570.1 will produce a valid ldif when run through slaptest. I believe that the expected behaviour should be that the declared objectIdentifier fooAttrOID should also be recognized when parsing the MAY or MUST clause of the objectClass declaration. Or is there a way to force slaptest to recognize it?

Re: (ITS#7041) Slapcat exporting bad data?
by Pierangelo Masarati 12 Sep '11

The value you see loginEmail:: IGpvY2tleTc1QGhvdG1haWwuY29t is $ echo -n 'IGpvY2tleTc1QGhvdG1haWwuY29t' | base64 -d && echo "" jockey75(a)hotmail.com (note the leading space). I suspect garbage in-garbage out, where LDAP browser is probably hiding garbage by trimming the leading space. You should check with ldapsearch(1) instead. Looks like incorrect data rather than a bug in slapcat(8). p.
