How to let users change their passwords?
by Steven Truong 27 Jul '10

27 Jul '10

Dear, all. I have been searching low and high for a tool that can let users to change their passwords in 389 DS or OpenLDAP? I think there is a real need for such a tool and I hope that people already wrote such a tool... Please share your ways of how you allow your users to change their passwords or other setup/architecture that allow this function. Beside that, I also recommend Apache Studio as a great tool to work with LDAP servers..... Thank you in advance.

slappasswd2.4 output issue
by Stuart Cherrington 27 Jul '10

27 Jul '10

Hi, I'm writing a script to help my fellow admins automatically creates user accounts in OpenLDAP 2.4. Can provide copy of script if you would like it. The issue I have is encrypting the plain text word into passwd format, I found the very helpful slappasswd2.4 which seems to work so I put it into my script: echo $NEWPASS > /tmp/newpass chmod 400 /tmp/newpass slappasswd2.4 -h {crypt} -T /tmp/newpass > /tmp/passenc chmod 400 /tmp/passenc EPASS=`cat /tmp/passenc` It creates an entry in the passenc file which looks like this: {crypt}mHUqpeNah1BOQ But when i use this as a variable to the 'userpassword:' attribute then try to compare passwds within phpLDAPadmin it fails. Any hints would be appreciated. Thanks, Stuart. _________________________________________________________________ http://clk.atdmt.com/UKM/go/195013117/direct/01/ We want to hear all your funny, exciting and crazy Hotmail stories.

Hi, An error comes while searching in ldap compiled with NDB support. To reproduce the issue: 1) Import the below sample.ldif file to the database by issuing the following command: /usr/local/sbin/slapadd -l sample.ldif sample.ldif: dn: dc=dimdim,dc=com dc: dimdim description: My wonderful company as much text as you want to place in this line up to 32K continuation data for the line above must have <CR> or <CR><LF> i.e. ENTER works on both Windows and *nix system - new line MUST begin with ONE SPACE objectClass: dcObject objectClass: organization o: Example, Inc. dn: ou=people, dc=dimdim,dc=com ou: people description: All people in organisation objectclass: organizationalunit dn: cn=Robert Smith,ou=people,dc=dimdim,dc=com objectclass: inetOrgPerson cn: Robert Smith cn: Robert Pagal cn: Howard Chu sn: smith uid: rjsmith userpassword: rJsmitH carlicense: HISCAR 123 homephone: 555-111-2222 mail: r.smith(a)dimdim.com mail: sampel1(a)yahoo.com mail: sample2(a)gmail.com description: swell guy ou: Human Resources 2) Start the ldap server and issue the command to search: ldapsearch -H ldap://192.168.3.47 -x -D "dc=dimdim,dc=com" -b "dc=dimdim,dc=com" -w dimdim "(uid=rjsmith)" 3) It will return multiple results and that is the issue we are facing.

how to add a new database with slapd.d?
by Zhang Weiwu 27 Jul '10

27 Jul '10

With Ubuntu 10.04, slapd is shipped by default using slapd.d configuration instead of slapd.conf. Referring to the document [1] I believe adding a new database should be as simple as adding a new file in slapd.d/cn=config/ But it doesn't work for me. Behavior explained below: I created this new database definition by copying example [2]: # cat "/etc/ldap/slapd.d/cn=config/olcDatabase={1}hdb" # BDB definition for example.com dn: olcDatabase={1}hdb,cn=config objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: {1}hdb olcSuffix: "dc=test,dc=com" olcDbDirectory: /var/lib/ldap olcRootDN: "cn=Manager,dc=test,dc=com" olcRootPW: secret olcDbIndex: uid pres,eq olcDbIndex: cn,sn,uid pres,eq,approx,sub olcDbIndex: objectClass eq olcAccess: to attrs=userPassword by self write by anonymous auth by dn.base="cn=Admin,dc=test,dc=com" write by * none olcAccess: to * by self write by dn.base="cn=Admin,dc=test,dc=com" write by * read According to my experience of using slapd.conf in the last five years, if I restart slapd, I should see DB_CONFIG and a few other files created in DB directory. But this is not happening this time. root@orphalese:~# ls -dlh /var/lib/ldap drwxr-x--- 2 openldap openldap 4.0K Jun 12 10:36 /var/lib/ldap root@orphalese:~# ls -lh /var/lib/ldap total 0 Quesiton: 1) did I do anything wrong? 2) What would you future suggest me to check? List of what I have checked: 1. Adding entry to the newly created database also doesn't work: # slapadd -b dc=test,dc=com < /tmp/first.ldif slapadd: slap_init no backend for "dc=test,dc=com" 2. I checked syslog with LogLevel set to 255, end up with a lot of details in syslog but none mentioning keyword 'hdb'. 3. The above experiment is re-done with hdb replaced with bdb without luck neither. 4. Authentication also fails: $ ldapsearch -x -D cn=Manager,dc=test,dc=com -w secret ldap_bind: Invalid credentials (49) 5. I also checked to make sure slapd.conf doesn't exist. 6. I also checked there is only one slapd.d directory and slapd is using the same slapd.d that I am editing, by the fact I changed LogLevel in cn=config.ldif and it has vivid effect on syslog. [1] http://www.openldap.org/doc/admin24/slapdconf2.html [2] The 'example' is "/etc/ldap/slapd.d/cn=config/olcDatabase=bdb" shipped with Ubuntu: # cat "/etc/ldap/slapd.d/cn=config/olcDatabase=bdb" # BDB definition for example.com dn: olcDatabase=bdb,cn=config objectClass: olcDatabaseConfig objectClass: olcBdbConfig olcDatabase: bdb olcSuffix: "dc=example,dc=com" olcDbDirectory: /usr/local/var/openldap-data olcRootDN: "cn=Manager,dc=example,dc=com" olcRootPW: secret olcDbIndex: uid pres,eq olcDbIndex: cn,sn,uid pres,eq,approx,sub olcDbIndex: objectClass eq olcAccess: to attrs=userPassword by self write by anonymous auth by dn.base="cn=Admin,dc=example,dc=com" write by * none olcAccess: to * by self write by dn.base="cn=Admin,dc=example,dc=com" write by * read

"objectClass: olcBdbConfig" causes "ldap_add: Invalid syntax" error
by Zhang Weiwu 27 Jul '10

27 Jul '10

Hello. This is again the problem of adding a new database with cn=config structure. Since I asked last question I now have much more knowledge to ask again with more understandable description of the problem, thus new post here. In short the problem is "objectClass: olcBdbConfig" causes "ldap_add: Invalid syntax" error. Step 1: fresh new Ubuntu 10.04 installation with slapd package. (Production server is Debian, but home PC is Ubuntu, try at home first, there hardly can be difference on server packages like slapd between Ubutnu and Debian) Step 2: Not being able to find default credential to access cn=config I added my own, adding these two lines to /etc/ldap/slapd.d/cn=config/olcDatabase={0}config.ldif olcRootDN: cn=Manager,cn=config olcRootPW: secret And test the new credential works. (how do I test? [1]) Step 3: Adding a new database definition from ldif file. Error: # ldapadd -x -D cn=Manager,cn=config -w secret < /tmp/ldif adding new entry "olcDatabase=bdb,cn=config" ldap_add: Invalid syntax (21) additional info: objectClass: value #1 invalid per syntax The file that caused the error is attached below, I could not see anything wrong in it and it is mostly copied from document[2] example. # BDB definition for example.com dn: olcDatabase=bdb,cn=config objectClass: olcDatabaseConfig objectClass: olcBdbConfig olcDatabase: bdb olcSuffix: dc=example,dc=com olcDbDirectory: /var/lib/ldap olcRootDN: cn=Manager,dc=example,dc=com olcRootPW: secret olcDbIndex: uid pres,eq olcDbIndex: cn,sn,uid pres,eq,approx,sub olcDbIndex: objectClass eq olcAccess: to attrs=userPassword by self write by anonymous auth by dn.base="cn=Admin,dc=example,dc=com" write by * none olcAccess: to * by self write by dn.base="cn=Admin,dc=example,dc=com" write by * read [1] To verify the credential I added to cn=config is usable I did this: # ldapsearch -x -D cn=Manager,cn=config -w secret -b cn=config | tail ,cn=auth manage by * break olcRootDN: cn=Manager,cn=config olcRootPW: secret # search result search: 2 result: 0 Success # numResponses: 6 # numEntries: 5 [2] ending page of this document: http://www.openldap.org/doc/admin24/slapdconf2.html

openLDAP and SSL client/server certs
by Bryan Boone 27 Jul '10

27 Jul '10

Hi everyone. I am trying to develop an ldap client that uses SSL. I read in the documentation on the openldap website this... You must also install a copy of the CA certificate on all of your client machines. Configuration is done in /usr/local/etc/openldap/ldap.conf: TLS_CACERT /usr/local/etc/openldap/cacert.pem Does this mean that the function ldap_start_tls_s()performs mutual SSL authentication??? If I want to achieve server side authentication, does that mean I will have to use the openSSL libraries to get the server cert prior to using the ldap_start_tls_s() function???
