smbk5pwd - slapd stops responding
by Eduardo Sachs 15 Mar '09

15 Mar '09

Hi People, I use the overlay smbk5pwd for sync password of Samba with the of Heimdal Kerberos. In Debian Etch using Samba 3.0.24-6etch10, OpenLDAP 2.3.30-5+etch2 and Heimdal Kerberos 0.7.2.dfsg.1-10, I don't have problems. But, in Debian Lenny using Samba 2:3.2.5-4, OpenLDAP 2.4.11-1, and Heimdal Kerberos 1.2.dfsg.1-2.1, I have problems. When I invoke smbpasswd or ldappaswd and trying change the password, slapd stops responding. With kpasswd I do not have problems, change the password of Samba and Kerberos correctly, and userPassword fixed with {K5KEY}, slapd not stops responding (working correctly), but, I need change the password with smbpasswd for Windows clients. Below follows a more detailed debug, has something else that I can show? This is a bug? slapd.conf configuration: moduleload smbk5pwd overlay smbk5pwd smbk5pwd-enable krb5 smbk5pwd-enable samba smbk5pwd-must-change 2592000 password-hash {K5KEY} - OpenLDAP have permission to read/write the file /var/lib/heimdal-kdc/m-key. - I configure OpenLDAP to run with user root and group root, for tests. smb.conf configuration about password: ldap passwd sync = Only unix password sync = no Look this example: 1 - LDAP OK: root# ps aux|grep slapd root 3841 3.0 0.8 21920 4512 ?

Hostname does not match common name problem
by Sascha 14 Mar '09

14 Mar '09

Hi there! I have a problem with an LDAP server that I need to connect to. I have the required certificate stored on the client but I am getting the following error message: "TLS: hostname (A.xyz123.com) does not match common name in certificate (*.xyz123.com)" Is there any way to work around this problem? As far as I understand it, RFC4514 section 3.1.3 allows wildcards thus the connection should work, shouldn't it? What is confusing me is that "openssl s_client -connect A.xyz123.com:636 -CAfile /etc/ssl/certs/rootca.cer" results in: Verify return code: 0 (ok) If I am not mistaken, openssl accepts the server based on the certificate but openldap does not. Any help is much appreciated. I am really stuck with this. Thanks. Regards, Sascha -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger01

CPU IOWAIT
by Sergio Cioban Filho 14 Mar '09

14 Mar '09

Hi all, I have 2 openldap servers running on CentOS 5.2 (openldap-2.4.11 RPM: http://staff.osuosl.org/~jeff/openldap/el5/i386/<http://staff.osuosl.org/%7Ejeff/openldap/el5/i386/>), the single-master replication works fine, but when I have activated mirrormode, any ldap interaction is so slowly and CPU IOWAT is 100% (in ldapsearch or ldapadd...). I have tried the same configuration with openldap-2.4.15 + db-4.7.25, but this problem still occurred. Have any idea about this problem? ** Sorry for my poor english... :) Thanks, Regards, --- Sergio Cioban Filho

newbie question: No anonymous authentication = problems
by Andreas Brudin 13 Mar '09

13 Mar '09

Hi, I hope I am on the right list for questions like this. I manage a OpenLDAP server installation on Ubuntu 8.10, and when I upgraded from 8.04 the configuration changed quite a bit. I am trying to turn off anonymous access, but I get problems connecting to the ldap database even when not using anonymous bind. I managed to find the configuration options I was looking for (at least i think so) with phpldapadmin. I found an object with dn olcDatabase={1}bdb,cn=config, in which I found an attribute called olcAccess, which I think is what I need to change. From the beginning it said: {0}to attrs=userPassword,shadowLastChange by dn.base="cn=manager,dc=mydomain,dc=com" write by anonymous auth by self write by * none {1}to dn.base="" by * read {2}to * by dn.base="cn=manager,dc=mydomain,dc=com" write by * read (of course with my dc values). I tried to change the last entry to by * none, as I do not right now need my users to be able to read their or other users' values. It worked as expected, from an LDAP point of view, I still could log in anonymously, but I could not browse the database, however, logged in as manager it worked as it should. The problem came in postfix, because I use my LDAP database (among other things) as an alias table. So I configured postfix not to bind anonymously, but to use server_host = localhost server_port = 389 search_base = dc=mydomain, dc=com bind = yes bind_dn = cn=manager, dc=mydomain, dc=com bind_pw = mysecret result_attribute = mail query_filter = (|(uid=%s)(mailAlias=%s)) But I got dict_ldap_lookup: Search error 50: Insufficient access from the mail.log When I changed back, it worked again. I have tried to change various things (such as put in by anonymous auth before by * read, and changing dc.base="..." to dc="..." both in the first and in the last attribute value above, but it does not seem to change. What am I doing wrong? Any help would be much appreciated. Best regards, Andreas

ldap delete and modifying by delete problems
by Catalin 12 Mar '09

12 Mar '09

Hello! I'm trying to write a php script in order to manage my LDAP Directory easier. Everything works fine when I'm adding new entries and when I'm modifying an attribute. When it comes to delete an entry from my directory or to remove an attribute, I get error no. 8 which means "PHP Warning: ldap_delete() [<a href='function.ldap-delete'>function.ldap-delete</a>]: Delete: Strong(er) authentication required in /var/www/html/admin.mydomain.tld/responsabil/sterge.php on line 34, referer: http://admin.mydomain.tld/responsabil/index.php?nav=del [Tue Mar 10 07:15:03 2009] [error] [client 172.17.26.57] PHP Warning: ldap_mod_del() [<a href='function.ldap-mod-del'>function.ldap-mod-del</a>]: Modify: Strong(er) authentication required in /var/www/html/admin. mydomain.tld /responsabil/sterge.php on line 37, referer: http://admin. mydomain.tld /responsabil/index.php?nav=del" Here is how I'm trying to do these: <?php $ldap = ldap_connect("localhost"); ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3); $r = @ldap_bind($ldap, "root","password"); $arrayCN=array("cn=",$login,",ou=people,dc=mydomain,dc=tld"); $CN=implode($arrayCN); $arraygroup=array("cn=",$row_verifica[5],",ou=departments,dc=mydomain,dc=tld "); $group=implode($arraygroup); $entry["member"]=$CN; $stergere=ldap_delete($ldap,$CN); $modificare=ldap_mod_del($ldap,$group,$entry); $closing=ldap_close($ldap); ?> I think it has something to do with LDAP settings. I'm using default settings for LDAP , I've only included a supplemental schema to fit it for my needs. I've generated a {SSHA} password for root. If needed, I can send all these files. Can anyone help? Any suggestion would be greatly appreciated. Thanks in advance! Best regards! Catalin

new ldap installation -LDAP newbie question
by Swenson, Chris 12 Mar '09

12 Mar '09

This is a bit difficult to articulate. Is there a way to move only the passwords from a passwd file into ldap? I have built out an ldap server and a client box and can successful authenticate from one to the other. I am using this to replace an old RHEL that has depended on the passwd file with nearly 10,000 users. To add the users to the new server I have parsed and imported a good deal of the data in the passwd file into on Oracle Db that has all the HR stuff and then scripted an output ldif to add the users into the new ldap server. Good so far, this works. My concern is thus. Ldap is on a new box. There is a lot of junk in the old box I want to leave behind, hence the rewrite via oracle. I want to extract only the passwords from the passwd file and write them to the new ldap server. If I run migrate_passwd.pl and pull the passwords out, they are hashed in some way and I cannot write them to the ldap nor script setting the password from the old one. Even if I run the passwd file through pwunconv they seem to be unusable. I dread the thought of having to communicate with 9000 students and nearly 1000 faculty and staff with new passwords. Regards Chris S.

Dear friends,looking to where we could specify config file path to be read by  ldapsearch.c  to /openldap/ldap.conf  will be trying to pass the query to ldapclient and obtain the result. should we write program starting from ldap_open , ldap_init, ldap_bind , ldap_search  or its suffice only by modifying ldapsearch.c.RegardsSantosh
