cn=config and mdb questions
by Da Rock 08 Dec '14

08 Dec '14

Aside from other issues (which haven't really been solved... just possibly worked around :/), I've been doing some tinkering and have raised some questions which I'm hoping will have answers to. 1. cn=config and friends: Looking at the schema and methods used to implement this config type, I got to considering that I could (in theory) name my databases such as olcDatabase=MyLDAPDatabase (or the like), rather than bdb/hdb/mdb. I then found that I couldn't and then looked it up to see why - I found that it had a naming restriction, but not why. Aside from possible limits within the programming as it stands now, is there some semantical issue why this is the case? Wouldn't possibly be easier to determine which database is which if the administrator was able to name them as they wish? 2. mdb: I know this is the way we're expected to go with ldap now, but what is the point of a db that can't grow as needed? It seems rather limiting (and old school - remember early unix programming on the old IBM mainframes and DOS for the PC's later with the 640k limit), so why the push in this direction? Or is it expected that this will be resolved in the future? Cheers

Re: Outlook LDAP Addressbook Browsing - Add ORDERING caseIgnoreOrderingMatch on CN or NAME core attributes without source code modification and re-compilition

Also it seems possible to modify the LDAP core schema attributes without recompiling... Please note that the following: - has not been tested and may not be fully accurate - is not recommended as you loose RFC compliance - does not apply directly to CN attribute as required for Outlook addressbook ( http://www.openldap.org/cgi-bin/wilma_hiliter/openldap-technical/201001/msg…) but process would be very similar... - may require an openldap version that allow core schema modification (2.4 or upper) === *Method1* (update core schema attribute via ldapmodify) Something like...

Of course that would need to be adapted to the openldap process and schema definition, as per version in use... === *Method2 *(edit core schema file core.ldif) - Obviously it is not recommended to directly edit core schema ldif files. Source: https://freeswitch.org/confluence/display/FREESWITCH/Polycom+Corporate+Dire… "...

A deep bow. You have helped me to conclude that I am having a ssl certs problem, rather than a ldap conf problem.keys I do openssl s_ client fr the master to the slave and vice versa. neither works. Do you mind telling me roughly or pointing me resources that explain what to do after i get an ok with openssl verify on the master? What to do to get the master to let the slave to connect and perform the syncrepl task. I have read some guides which tell me to concatenate the ca cert of the master to that of the slave. some others tell me to use the the ca cert of the master for the slave. so what to do? do the certs and keys have to be shared in some way like setting up ssh?

Hi, thanks again for offering further help. Is what you suggesting, c_rehash, equivalent to updating the certificate database, just like what the update-ca-certificate script would do in debian- based distro? I did not do this rehash thing. In the master, I am using an old set of certs which I suppose to be working. In the slave, I put all the certs in the directory they were first gen.erated, as given in the conf file. Will rehash work properly with the certs in those paths (i.e. /etc/pki/CA/)?I So what to do with the output of openssl x509 -noout -text -in <your_certificate>? I cannot try it now. I have tried sth similar a couple of hours ago that output the content of a cert in text. For the master, the issuer is an external orgaization which we bought the cert from. For the slave, the issuer is my orgaization since I generate it myself. I follow the guide in the link to paste the master ca cert after the orig slave ca cert. Does that strange instruction screw things up?I Thanks again in advance. ------------------------------ On Mon, Dec 1, 2014 11:05 AM GMT Ulrich Windl wrote: >>> wailok tam <wailoktam(a)yahoo.com> schrieb am 01.12.2014 um 11:40 in Nachricht ><1171333883.1885274.1417430400586.JavaMail.yahoo(a)jws100208.mail.ne1.yahoo.com>: >> Hi, thanks for your help.

Re: adding a custom attribute

Hello Quanah, Thank you for your reply. Do I create a new schema file for my new attribute as in ${new_attribute}.schema and another for the new object using this new attribute?

Obtaining the hashed password using ldapsearch, from aWwindows 2012 server.
by Mark London 02 Dec '14

02 Dec '14

Hi =- We upgraded the OS of our Active Directory server to Windows 2012. On a linux computer running Redhat 5, we use a script to obtain an account's hashed password, using the ldapsearch command. We request the msSFU30Password attribute. The script works fine for any account that was created before the new server was installed. For new accounts, no password is returned. Does anyone know how to make this possible again? One suggestion by someone, was to install the "Services for Unix <https://en.wikipedia.org/wiki/Windows_Services_for_UNIX>" package, which is now deprecated (I can't find what replaces it!). I installed it, but it didn't seem to help. Any other suggestions? Thanks. Mark London MIT PSFC

Have problem searching against ldap server after asyn sasl bind
by Qian Li 02 Dec '14

02 Dec '14

Hi All, Recently, I tried to write a ldap client to do ldap search asynchronously, but failed to perform search operation after a successful async sasl (digest-md5) bind. I’ve tried some code, but only succeeded in searching in synchronized sasl bind. I compared the captured sync and async packets: In sync bind, the search packets were encrypted. In async bind, after sasl (digest-md5) binding to ldap server asynchronously (by calling ldap_sasl_interactive_bind() twice), ldap_search_ext() was called. But the search packet was in plain text. Then the ldap server reset the connection or just didn’t response (in the case of MSAD). Did I use the ldap API incorrectly? Or async sasl bind doesn’t support search operation? Any suggestion will be appreciated and sorry for my poor English.
